特细砂混凝土配制的易性和抗压强度试验研究与分析

Experimental Study and Analysis of the Workability and Compressive Strength of Extra Fine Sand Concrete

在神东矿区基础上,遵循就地取材的原则,对合理开发利用地方资源,降低工程建设造价问题,本文提出特细砂混凝土研制中存在的易性,以及不同粉煤灰的比例对特细砂混凝土的抗压强度的影响实验研究,对创新应用特细砂混凝土技术有重要意义。研究得出:①特细砂混凝土的不同配比与易性相关性;②不同粉煤灰比例对特细砂混凝土的坍落度的影响;③不同粉煤灰比例对特细砂混凝土的抗压强度影响机理。

On the basis of Shendong Mining Area,following the principle of obtaining local materials,for the issues of local resources rational development and utilization and the project construction costs reduction,this paper proposes the experimental study on the workability of ultra-fine sand concrete,and the influence of different fly ash ratios on the compressive strength of ultra-fine sand concrete,which is of great significance for the innovative application of fine sand concrete technology.The study shows:①the correlation between the different proportions and workability of ultra-fine sand concrete;②the influence of different fly ash ratios on the slump degree of ultra-fine sand concrete;③the mechanism of influence of different fly ash ratios on the compressive strength of ultra-fine sand concrete.
