Description

Fly ash cement prepared from high early strength cement (HPC) and fly ash (FA) was proposed and its ecological evaluation was performed. It has the following characteristics. Compared to ordinary portland cement (OPC), it has a shorter set time and has similar hardening characteristics to those of HPC. Its early strength up to age 7 days is higher. Its adiabatic temperature rise was about the same as that of OPC. Based on the ecological evaluation, the fly ash cement prepared from HPC and FA can reduce CO2 gas emission at its production by 20 mass% compared to OPC.
