Abstract：To step up urbanization construction and to reduce CO2 emissions,waste glass and limestone had been solidified into construction materials with flexural strength more than 25 MPa under hydrothermal conditions by simulating diagenetic mechanism of underground.The experimental temperature was under 200 ℃,so the products can achieve CO2 zero emission.The content of inorganic additives,curing time and temperature will affect the strength of products,and the experimental results show that the development in strength is mainly due to the formation of tobermorite and calcium silicate hydrate(C-S-H).
