Development and evaluation of environment-friendly lightweight self consolidating concrete: from material characterisation and durability assessment to structural performance

Construction, one of Canada's leading industries, significantly contributes to the emission of greenhouse gases and the depletion of natural resources. Construction activities consume more raw materials by weight than any other industrial sector. As much as 50% of all materials extracted from the earth's crust are transformed into construction materials and products. In addition, the built environment accounts for the largest share of greenhouse gas emissions (about 40%) in terms of energy end usage. Development of new environment-friendly building materials can lead to lower greenhouse gas emission, greater consumption of waste, durable construction, optimal sustainable use of renewable resources, enhancement of material recyclability, and overall sustainable development.
