Climate change, and carbon dioxide's (CO2) leading role in it, are globally acknowledged problems. Mitigation strategies are being proposed in many fields, and construction industries must follow suit. Canadian concrete use is higher than any other construction material, and considerable CO2 emissions are one by-product of this. Global studies have examined partially replacing singular components of concrete mixes to reduce the environmental footprint - with most focusing on replacing aggregates with waste materials. However, since the use of Portland cement accounts for the majority of concrete's carbon footprint, alternative cementing technologies can have a large potential to greatly impact the sustainability of concrete.

气候变化和二氧化碳（CO2）在其中的主要作用是全球公认的问题。许多领域都提出了缓解策略，建筑行业必须效仿。加拿大混凝土的使用高于任何其他建筑材料，并且相当大的二氧化碳排放量是其中一种副产品。全球研究已经检查了部分替代混凝土混合物的奇异组成部分，以减少环境足迹 - 大多数集中于用废料代替聚集体。但是，由于波特兰水泥的使用占了混凝土占碳足迹的大部分，因此替代水泥技术可能具有很大的潜力来极大地影响混凝土的可持续性。
