Cementitious composition containing glass powder as a pozzolan

摘要

Cementitious compositions, which may make use of waste glass, comprise glass material, calcined kaolin and a cement. Also provided are cementitious binders and solidifiable cementitious compositions (such as mortars and concretes) incorporating the cementitious compositions. The cementitious composition is mixed with water to form the cementitious binder, and aggregate is added to the cementitious binder to form the solidifiable cementitious compositions. Solidifiable cementitious compositions formed from the cementitious compositions have comparable or superior short-term strength and superior long-term strength to solidifiable cementitious compositions formed from conventional cementitious compositions.
