Ce projet est en collaboration avec ISIS Canada. Selon la norme A23.1 de l’Association canadienne de normalisation (CSA), l’occlusion d’air est obligatoire dans le béton exposé aux chlorures, non seulement dans les environnements soumis au gel-dégel, mais également dans les environnements non soumis au gel-dégel. Le béton aéré présente certaines difficultés de finition à la […]

This internship is in partnership with ISIS Canada. The Canadian Standards Association (CSA) Standard A23.1 requires air entrainment in concrete subjected to chlorides, not only for freeze-thaw environments but also for non‐freeze-thaw environments. Air entrainment presents some challenges in finishing of power trowelled surfaces, for example parking decks. Depending on the timing and amount of […]

In the coming months, a new set of energy efficiency targets called “step codes” will be incorporated into the standards used to build houses. The step code is intended to provide builders with a better understanding of what is expected of them when they build energy efficient homes. It will also allow municipalities incorporate energy […]

Slab bands are a common structural system in North America due its general economy. At the slabband/column connection, unbalanced moments are being transferred that could lead to a common failure mechanism termed punching shear failure. This type of failure occurs when the column and a portion of the slab punches through the remaining slab. Thus, […]
