Study on the Promoting Effect of Limestone Powder on RPC Hydration
In order to promote the wider application of limestone powder in the construction field,the effects of different fineness and dosage of limestone powder on the workability and chemical binding water content of RPC mixtures were experimentally studied.The research results indicate that limestone powder can accelerate the RPC hydration reaction,and the hydration reaction accelerates with the increase of limestone powder fineness and dosage.After comprehensive analysis,11 μm(1250 mesh)limestone powder should be preferred,and the optimal dosage is 20%.
