Experimental Studies on the Impact of Waste Mineral Admixtures on Concrete Properties

Abstract:

As the common waste of the production in daily life,a large number of stone powder, fly ash, coal gangue was abandoned, and it causes large tracts of land was occupyed and the environment was polluted. Therefore it is great singnificance to saving resources and protecting environment by studing the impact of the three kinds of wastes as mineral admixtures on the properties of concretetTest shows that when the replacement rate of the three kinds of admixture is 20%, the replace quanity is considerable and the basic requirements on compressive strength, the anti-permeability performance, frost resistance of the concrete can be satified;when the replace content of the stone powder or fly ash is 30%, the performance of the concrete decreases, it only can be applied in the engineering whose quality requirement is relatively low; the properties of the concrete can't meet the requirement of the engineering application when the the replacement rate of the coal gangue is 30%.
