Replacing fly ash with limestone dust in hybrid cements

Hi! Last week I posted my question about fly ash market. Most engineers can predict that fly ash supply will reduce eventually. This time, I wonder limestone powder can be a substitute (supplementary cementitious materials) for fly ash. This means calcined lime is ...

The effect of limestone powder and fly ash on magnesium sulfate resistance of mortar was studied by testing on the strength, expansion and hydration products of the specimens stored in MgSO4 solution at certain periods. The experimental results show that the strength of mortar stored in MgSO4 solution increases a little before 28 d, but decreases fast subsequently. The more the contents of ...
