大掺量磨细粉煤灰混凝土单轴受压应力应变全曲线的试验研究

普通混凝土和高强混凝土的应力应变曲线,国内外已开展了大量的研究。但有关掺磨细粉煤灰混凝土应力应变全曲线资料却不多见,本文配合粉煤灰混凝土的推广应用,对其单轴受压性能及应力应变关系进行试验研究,同时给出了适用于不同强度等级掺磨细粉煤灰混凝土受压应力应变全曲线的统一数学表达式,与试验曲线吻合较好,可供进一步研究参考。

Experimental Study on Uniaxial Compressive Stress-Strain Curve of Large Dosage Pulverized Fuel Ash Concrete

The research on stress-strain curve of ordinary concrete and high strength concrete have done at home and abroad.But,it is few about the data of stress-strain curve of pulverized fuel ash concrete.This paper combined with the popularization and application of fly ash concrete,made experimental study on its uniaxial compressive properties and stress-strain relation,at the same time,this paper gave unified mathematical expression which applies to compressive stress-strain curves of different strength grade mixed fly ash concrete,and it is identical with the experimental curve,which is available for reference and further research.
