Discutons d'une éducation ouverte et durable
<p>Le 22 mars 2024 s’est déroulé un café jasette sous le thème de l’éducation ouverte et durable. Cet événement convivial a été organisé à l'Université de Sherbrooke dans le cadre du Mois de l'éducation ouverte et de la Semaine des ODD. Ce fut le moment de rassembler différentes parties prenantes de la communauté universitaire pour échanger et réfléchir à la synergie possible entre les enjeux de réussite étudiante, d'éducation ouverte et du développement durable, au bénéfice des personnes étudiantes. Le but de cette jasette étant d’apporter différentes perspectives à ces enjeux et d'identifier des synergies possibles. Pour alimenter les réflexions, des définitions et des pistes de réflexion étaient mises à disposition.</p> <p>Réalisée en temps réel par la graphiste Mylène Choquette, une illustration graphique témoigne de la richesse et la diversité des interventions. Bien qu’attrayante, l'illustration d’une telle discussion représente les réflexions des personnes présentes et l'état de la discussion et non l’ensemble de la littérature autour de ce sujet. Un plus à cette formule est certainement que dans ce genre de représentation, il y a de l’ouverture pour aller plus loin dans les réflexions et faire émerger de nouvelles relations et perspectives sur les enjeux de départ. </p> <p>Cette activité fut possible grâce à la participation du Service de soutien à la formation de l'Université de Sherbrooke et à la contribution financière de i-mersion CP, fabriqueREL et du Vice-Rectorat aux études de l'Université de Sherbrooke.</p>

Supplementary data for the paper: "Enhancing concrete durability in chloride-rich environments through manual application of healing agents"
<p>Supplementary data for the paper: “Enhancing concrete durability in chloride-rich environments through manual application of healing agents”.<br><br>Open data concerning experimental work. The paperinvestigates the use of three potential healing agents: water-repellent agent (WRA), sodium silicate (SS), and polyurethane (PU). The agents are tested separately under two conditions: exposure to a 3.3% NaCl concentration at 20°C and exposure to cyclic freeze-thaw conditions. The agents are manually injected into the cracks and evaluated for their healing efficiency using the capillary absorption test and microscopy analysis. Additionally, their resistance to freeze-thaw cycles by monitoring mass loss and chloride bulk diffusion is measured using sprayed silver nitrate, titration, and EDX mapping. </p>

I alternate therefore I generalize: how the intrinsic resistance risk of fungicides counterbalances their durability
<p>The evolution of resistance to pesticides is a major burden in agriculture. Resistance management involves maximizing selection pressure heterogeneity, particularly by combining active ingredients with different modes of action. We tested the hypothesis that alternation may delay the build-up of resistance not only by spreading selection pressure over longer periods, but also by decreasing the rate of evolution of resistance to alternated fungicides, by applying an experimental evolution approach to the economically important crop pathogen <i>Zymoseptoria tritici. </i>Our results show that alternation is either neutral or slows the evolution of resistance, relative to continuous fungicide use, but results in higher levels of generalism in evolved lines. We demonstrate that the relative risk of resistance intrinsic to fungicide alternation probably underlies a trade-off between the number of fungicides and the frequency of alternation. This trade-off is also dynamic over the course of resistance evolution. These findings open up new possibilities for tailoring resistance management effectively while optimizing interplay between alternation components.</p>

Development of Novel Ultra-High Performance Engineered Cementitious Composites (UHP-ECC) for Durable and Resilient Transportation Infrastructure
<p>The objective of this study was to develop novel UHP-ECC materials utilizing readily available ingredients in Region 6 for the construction and repair of transportation infrastructure. Phase one of this study focused on the development of ultra-high strength cementitious matrices by evaluating the effects of ingredient selection and mixture proportioning on the materials’ compressive strength. Variables evaluated included the mass ratios of silica fume to fly ash (SF/FA), supplementary cementitious materials to cement (SCMs/C), and ordinary sand to microsilica sand (OS/MS). Phase two of the study focused on the development of UHP-ECC materials. To this end, based on the knowledge gained from phase one, two ultra-high strength cementitious matrices (one with and one without SF) were formulated and their fracture properties were evaluated through fracture toughness test. Furthermore, fiber-bridging properties of ultra-high-molecular-weight (UHMW) polyethylene (PE) fiber in the developed cementitious matrices were evaluated through single crack tensile test (SCTT). Four different composites were produced by reinforcing the selected cementitious matrices with 1.5 and 2 vol.% UHMW PE fiber. Fresh and hardened properties of the developed composites were assessed by means of flowability test, compressive strength test, uniaxial tensile test, and flexural performance test. Results from phase one showed that SF/FA had the most relevant effect on compressive strength, followed by SCMs/C, and OS/MS. Furthermore, increments in SF/FA produced improvements in strength, whereas increments in SCMs/C and OS/MS reduced strength. Experimental results from phase two indicated that the use of SF and the increase in fiber content generally had a negative effect on the fresh and hardened properties of the composites. These observations were credited to a worsening fiber distribution when using silica fume and/or increasing fiber content. Three UHP-ECC materials utilizing readily available ingredients were successfully developed (i.e., mixtures FA25-f1.5, FA25-f2, and FA20SF5-f2). These materials simultaneously exhibited ultra-high compressive strength (>120 MPa) and ECC-like ductility (tensile strain capacity >2%). The average crack width for all mixtures ranged between 61-131 μm. Mixture FA25-f1.5, which displayed the best mechanical properties, exhibited a compressive strength of 133.1 MPa, flexural strength of 21.4 MPa, tensile strength of 10.3 MPa, tensile strain capacity of 4.3%, and an average crack width of 115.3 μm. Importantly, this mixture did not incorporate silica fume or microsilica sand and used low fiber content (i.e., 1.5 vol.%).</p>
Durability of Concrete Produced with Alternative Supplementary Cementitious Material
<p>Historically, Class F fly ash has been chosen as a supplementary cementitious material (SCM) in concrete for its ability to mitigate alkali-silica reaction (ASR). However, future availability of fly ash is uncertain because the energy industry has been investing in renewable energy production and removing coal burning generating stations from operation. Consequently, there is a growing need to find new, cost effective and environmentally friendly alternatives to fly ash. This study investigated a locally available natural pozzolan mined from a pumicite deposit near Espanola, NM for its ability to mediate ASR. Concrete and mortar mixtures included SCM contents ranging from 10 to 40%. Mortar bar tests and concrete tests for compressive and flexural strengths, shrinkage, frost resistance, chloride permeability, and surface resistivity were performed to assess the effectiveness of the pumicite. A minimum pumicite content of 20% was needed to mitigate ASR and that mortar mixtures containing 30% natural pozzolan had approximately 40% less expansion than mixtures containing 30% fly ash, indicating that the pumicite was substantially more effective at mitigating ASR than fly ash. Concrete mixtures containing natural pozzolan had comparable compressive strengths to specimens containing fly ash, while flexural strengths of specimens containing pumicite exceeded those of mixtures containing only fly ash. Concrete shrinkage decreased as pumicite content increased and when fly ash was used in place of pumicite. Fly ash mixtures produced at least 20% less shrinkage than similar 30% pumicite mixtures, indicating that the pumicite produced significantly greater shrinkage than the fly ash. Results also showed that mixtures containing 20 and 30% pumicite had the lowest acceptable durability factor (DF) values, and these DF values were significantly less than the DFs obtained using 30% fly ash. Rapid chloride permeability testing results showed that increasing pumicite content decreased chloride ion penetration. The 28-day surface resistivity results showed that the mixtures most susceptible to chloride ion penetration were the mixtures that contained either 10% natural pozzolan or 30% fly ash. Mixtures containing 30% fly ash provided substantially less chloride ion penetration resistance than mixtures containing 30% natural pozzolan at 28 days, but slightly better chloride resistance at 180 days. These results indicate that pumicite can reliably replace (partially or completely) fly ash for all of the durability issues addressed in this work.</p>

Edmonton Concrete Piles: Ensuring Durability and Longevity in Construction
<p>Among the many construction uses for precast <a href="https://goo.gl/maps/DJzVVHVY4uKxB3Ez6"><strong>Edmonton Concrete Piles</strong></a> are foundations, bridges, and marine structures. Their strength and versatility make them ideal for supporting heavy loads and structures in challenging soil conditions. New construction, as well as renovations and repairs to older structures, frequently make use of precast concrete piles. The ability to insert precast concrete piles into the ground with minimal interference to nearby regions makes them a desirable option for reinforcing and repairing foundations.</p> <p>Buildings designed by engineers can be supported by this type of piling. This is suitable in the majority of cases and applies to all types of businesses. The use of precast concrete piles is justified in situations where dry strata lie over soft sediment. Furthermore, they are effective even on soil that is polluted or otherwise unfriendly.</p> <p>They are adaptable to many different types of soil and can be shaped with the help of a pile cropper. This is especially true when reducing the items to the recommended pile cutoff level. One reason they have been around for so long is because they provide a cost-effective piling solution in this way.</p> <p>Reinforcing and supporting foundations are just two of the many applications that benefit from their robust character and ability to endure tough soil conditions. Due to their little effect on the surrounding areas during construction, precast concrete piles are an eco-friendly option. If builders are aware of the advantages of precast concrete piles, they may choose the finest foundation solution for their projects.</p> <p>The installation of concrete piles does not typically result in significant material waste or degradation, therefore they are highly advantageous. The question is, how can we put these mounds to good use? What keeps them from being anything other than stalwarts in their construction industries? Regardless, what makes them stand out from the crowd?</p> <p>For more information about our Concrete Piles service, contact Shield Foundation Repair now!</p> <h2>Concrete and Ever Staff Precast Piles</h2> <ul> <li>A lot of industries still use precast concrete piles as their go-to. This becomes most apparent when building strong, long-lasting foundations. This is mainly due to its remarkable flexibility and resistance to corrosion.</li> <li>The fact that the piles may be linked to create longer ones makes it a versatile solution as well. One of the primary uses for these heaps is really in this context. The transportation of segmented piles opens up a world of possibilities for building projects of varying lengths.</li> <li>Do you want to know more about the finest cutting tools, pile cropping, or the foundation of concrete piles?

Another option is to contact us for additional information regarding our top-notch piling services.</li> </ul> <h2>Grasping the Benefits of Steel Sheet Pile Construction</h2> <p>Steel sheet piles, thanks to their exceptional strength and resistance, are the ideal choice for foundations in soils that are difficult to work with. Their capacity to provide stability and resistance to lateral pressures is a key feature that makes them ideal for use in retaining walls, underground parking lots, and waterfront complexes, among other uses.</p> <p>Steel sheet piles last longer and need less upkeep due to their high corrosion resistance. Their versatility allows for efficient installation and removal, reducing environmental impact. Steel sheet piles have many advantages as a construction material, including durability, longevity, and structural performance.</p> <p>One major benefit of steel sheet piling is its extraordinary strength. Steel can withstand severe weather and heavy loads since it is strong and durable. This makes steel sheet piling an ideal material for retaining walls along roads railroads, or any other project that needs to keep a lot of dirt or water contained.</p> <p>Steel sheet piling has many positive uses in construction and also has environmental benefits. Steel sheet piling may be recycled and repurposed once its useful life is done because <a href="https://www.shieldfoundationrepair.ca/services/underpinning/"><strong>Edmonton Steel Piles</strong></a> is a recyclable material. Because of this, steel sheet piling is a sustainable option for long-term projects like retaining walls.</p> <p>Shield Foundation Repair Inc. has been a leading supplier of steel sheet piles to the building industry on every continent for a long time.</p> <h2>How are piles produced, and what kinds of piles are there?</h2> <ul> <li>For centuries—if not millennia—piling has been and is an essential part of the building industry. Transferring weight from an elevated structure to the ground is the primary function of piles.</li> <li>The definition and background of piling will be covered in the first part of this course. The article continues by explaining the two main kinds of pile foundations, the steps involved in building and installing piles, and the importance of using safe working platforms to support piling rigs.</li> <li>Property subsidence can be secured in an affordable and non-invasive manner with screw piling underpinning. This method stops any additional movement caused by factors such as groundwater loss, trees getting larger over time, or roots absorbing enormous amounts of water from the earth.</li> </ul> <p>Using our screw piling foundation technology as an underpinning solution is a perfect match. The inability to employ a larger machine for excavation due to restricted access is a prime example of this. Then, to be safe, we'll pour concrete or use crushed debris to encircle the screw pile underpin cap and prevent the building from shifting any further. The current state of the ground following excavation will inform our engineer's decision on this matter.</p> <p>If you see any signs of building sinking or cracks, don't hesitate to contact Shield Foundation Repair Inc. Our professionals can remedy it quickly and affordably.</p> <p> </p> <p> </p>
The effect of particle board industry waste tar on the physical and biological durability of wood
<p>This manuscript investigated the effect of waste tar from particle board factories on some physical and biological resistance properties of Scots pine (<em>Pinus sylvestris </em>L.) and beech (<em>Fagus orientalis </em>L.) woods. Solutions were prepared by dissolving waste tar in ethanol:toluene (1v:1v) in concentrations of 5%, 10%, 15% and 20% and treated under vacuum and pressure. In addition, surface coating (SC) was applied by spreading 96% waste tar on the wood surfaces after treatment. Deep-treated and surface-coated (DT+SC) wood samples were exposed to the wood-decay fungi (<em>Corillous versicolor</em> L. and <em>Neolentinus lepideus</em> Fr.) and wood destroying house borer (<em>Hylotrupes bajulus </em>L.) larvaes. Total phenolic content, water uptake, water-repellent efficiency and surface contact angle were tested. The highest mean weight loss (45.23%) was found in the beech wood control samples exposed to <em>C. versicolor</em>. Beech samples deep-treated with a 20% concentration and surface treatment (DT+SC) yielded a mass loss of 14.03%. The <em>H. bajulus</em> larvae mortality rate was found to be 80% in the Scots pine wood samples deep-treated with 20% waste tar. The deep treatment with the waste tar solution significantly increased the surface contact angle values of the Scots pine wood, thereby significantly reducing the wettability of the wood compared to the untreated control samples. </p>
