Title: Research and application of limestone powder in polycarboxylate superplasticizer concrete
Abstract: The impact of polycarboxylate superplasticizer concrete that added limestone powder was researched.Through the experiment and the result analysis of workability,slump and extended degree and the compressive strength of green concrete which was under different limestone proportion,research the function and effect of limestone powder in concrete,and apply the limestone powder to production.The result of experiment indicated that mixing with limestone powder could decrease the slump loss,and increase the concrete workability;the concrete compressive strength would be decreased by limestone powder increased,the range of C30 concrete compressive strength was obvious,but C40 concrete compressive strength within a narrow range.In the progress of production,adding 30 kg/m3 limestone powder into C30 polycarboxylate superplasticizer concrete is safe and feasible.
