再生硫铝酸盐水泥

Recycled Calcium Sulfoaluminate Cement

A low-carbon cementitious material produced by calcining concrete waste with CaSO4 and Al2O3 to form ye'elimite, which hydrates to form ettringite and C─S─H for high strength. / 一种通过将混凝土废料与CaSO4和Al2O3煅烧形成硫铝酸钙（ye'elimite），其水化生成钙矾石和C─S─H以实现高强度的低碳胶凝材料。
