Study on the Influence of Limestone Dust on Performance of Cement Mortar

Abstract:

This paper uses dust, with particle size less than 0.08mm, produced by crushing limestone to replace the same amount of cement in different proportions and studies the performance of cement mortar. The result shows that limestone dust has water reducing effect and does not reduce strength of the mortar when its dosage is less than 12%, meanwhile, it can improve the shrinkage property and the durability resisting sulfate, which explains that limestone dust is not the inert material, but has a certain activity,.
