Optimum Mix Ratio of Alkali-activated Cementitious Materials in Road Engineering
In order to study the best mix ratio,alkali-activated cementitious material was tested at different ratios.The higher the ratio of metakaolin and fly ash,the better the flexural property of alkali-activated cementitious material.But too much fly ash will reduce the compressive strength of the material,so the amount of fly ash should not be too much;When the amount of meta kaolin,fly ash and alkali activator is fixed,reducing the amount of cement,increasing the amount of lime,gypsum and water glass will reduce the compres-sive strength of alkali-activated cementitious material,finally,the optimal mix ratio of alkali-activated cementitious materials was ob-tained.
