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

Abstract:

This paper use dust particles which is produced by crushing limestone to replace the same amount of cement in different proportions, study the performance of cement mortar, and determine the best dosage of limestone dust. Its size is less than 0.08mm. The result shows that limestone dust has water-reduce effect and does not reduce the strength of the mortar when the dosage of limestone dust is less than 12%. Meanwhile the addition of limestone powder can improve the shrinkage property and the durability of sulfate. It explains that limestone dust has a certain activity, not the inert material.
