Experimental Study of Composite High Strength Self-Compacting Concrete

Abstract:

This test uses polycarboxylate superplasticizer by adding 15% quantitative fly ash, 10%, 15%, 20% of slag, and 5%,7.5%, 10% of silica fume of the total amount of the cementitious material to be an equivalent replacement for cement. Ordinary materials were used to make the C70 high strength self-compacting concrete. The concrete slump, expansion degree, and the axial compressive strength of concrete were studied. Through testing, the mix proportion of each group of concrete slump was determined to be above 250mm. And the expansion degree to be above 550mm. The axial compressive strength satisfied the design strength value. At the same time, the optimal mix ratio was proposed. And the economic performance of each group was analyzed. There are references for a similar experimental design and engineering application.
