Experimental Study on Effect of Paste-Aggregate Ratio on Properties of Expansive Concrete with Fly Ash

ZHANG Jianbo;DU Yingji;Guiyang Engineering Corporation Limited,Power China;College of Water Resources and Architectural Engineering,Northwest Agricultural and Forestry University;  
The overall calculation method was applied to calculate the mix design of expansive concrete with fly ash and studied the paste-aggregate ratio for the influence of expansion properties,strength properties and the development coordination of both. The main conclusion is as follows: no matter how expansive ash,when fly ash is low( 10%),paste- aggregate ratio is relatively larger( 37. 5 /62. 5),the more favorable to the coordinated development of the system expansion and strength; when compared with fly ash is high( 30%),paste- aggregate ratio decreases,the more favorable to the coordinated development of the system expansion and strength. So not in the all types of concrete optimal paste- aggregate ratio are determined as 35 /65,this experience is in a certain range for different types of concrete.
