摘要
为得到简单配比的水泥净浆单轴受压力学性能,进行了2种配合比的水泥净浆试件试验,给出了试验现象与破坏过程,得到了水泥净浆试件力学性能指标。分析了弹性模量变化规律,给出了以水泥净浆棱柱体抗压强度为基础的弹性模量计算公式。分析了水泥净浆单轴受压应力-应变曲线上升段变化规律,采用混凝土规范公式拟合得到了水泥净浆单抽受压应力-应变曲线上升段计算公式,给出了曲线参数取值。给出了通过强度计算得到水泥净浆弹性模量及应力-应变曲线上升段的计算方法,为工程实践及采用水泥净浆进行分析提供基础素材。
In order to get the mechanical properties of simple cement paste subjected to uniaxial compression,2 mix proportion cement paste were tested.Phenomena in the experiment and destruction process were described,and the mechanical property index of cement paste was given.Law of elasticity modulus was analyzed,and the calculation formula of elasticity modulus of cement paste based on the prism compression strength was obtained.The law of ascending stage in stress-strain curve of cement paste subjected to uniaxial compression was analyzed.The calculation formula of the ascending stage was gotten by curve fitting conforming to the formula in concrete design code.The parameters in the curve were given.The calculation of elasticity modulus of cement paste and the ascending stage of the stress-strain curve were given in this paper,which would provide basis for actual engineering practice and analysis using software.
