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

建筑业是加拿大的主导产业之一，是温室气体排放和自然资源枯竭的重要原因。按重量计算，建筑业消耗的原材料比其他任何工业部门都多。从地壳中提取的所有材料中，多达50%被转化为建筑材料和产品。此外，就能源终端使用量而言，建筑环境在温室气体排放中所占份额最大(约40%)。开发新型环保建筑材料可以减少温室气体排放，增加废物消耗，耐用建筑，优化可持续利用可再生资源，增强材料回收能力，实现整体可持续发展。

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.
