The Properties of High-Strength Concrete Containing Super-Fine Fly Ash and Limestone Powder

Abstract:

In this study, a high-strength concrete containing 25% super-fine fly ash and 10% limestone powder was prepared, and its properties were investigated by comparing with those of pure cement concrete. The results show that the concrete containing super-fine fly ash and limestone powder can get a larger initial slump and a smaller slump loss than the pure cement concrete with the same super plasticizer content. In the case of almost the same 28 days' compressive strength, the concrete containing super-fine fly ash and limestone powder exhibits a lower adiabatic temperature rise, a lower early strength, a higher late strength, a lower permeability, and a larger carbonation depth than the pure cement concrete.
