Influence of Fly Ash Content and Desert Sand Replacement Ratio on the Static Elastic Modulus of Desert Sand High Strength Concrete

摘要

In order to study the influence of fly ash content and desert sand replacement ratio on the static elastic deformation of desert sand high strength concrete, experiments on 28d static compression modulus of desert sand high strength concrete with different fly ash content and desert sand replacement ratio were carried out. The regulation on the influence of fly ash content and desert sand replacement ratio on 28d static compression modulus of desert sand high strength concrete was analyzed. Experimental results showed that with the increase of desert sand replacement ratio, 28d static elastic modulus of desert sand high strength concrete increased firstly, then declined. With the enhancement of fly ash content, 28d static elastic modulus of desert sand high strength concrete declined.
