摘要： Rapid curing, high strength cementitious binder mixtures are provided containing fly ash and an alkali silicate binder that has a weight ratio of SiO2:M2O of about 0.20:1 to about 0.75:1 wherein M is selected from the group consisting of Li, Na, K, Ca and Mg. The cementitious binder mixtures can be mixed with aggregates to provide mortar and concrete mixtures. Any of the binder, mortar and concrete mixtures can be cured under elevated temperatures to yield high strenght products.
