Experimental Study on Effect of Limestone Powder on Concrete Properties in Mechanism Sand

Abstract

In this paper, the influence of lime powder in mechanism sand on the performance of concrete is studied, and a lot of research is carried out on the properties (workability and compressive strength) of concrete through lime powder (content or quality), in order to obtain reasonable and scientific conclusions and data, to better promote the improvement of the performance of mechanism sand concrete, and finally to provide effective reference and help for the application of mechanism sand concrete.

Keywords:

• Machined sand
• calcareous powder
• quality
• workability
• compressive strength
