摘要:
在复合材料力学理论与流变学开尔文模型基础上建立了一个用以描述水泥浆体水化早期弹性模量成长的模型.该模型从微观角度出发,在假设水泥颗粒与水化产物为圆球状且水泥浆体形成的孔结构为圆孔形的基础上,应用线弹性理论与有孔介质力学理论研究随着时间的增加、水化度不断增大的情况下,硬化水泥浆体的有效弹性模量.将该有效弹性模量与流变学开尔文模型理论结合起来得出初凝后水泥浆体弹性模量时变方程.研究结果表明:该模型可用于描述水泥浆体初凝后的弹性模量变化,且其变化规律与精度和实验数据符合良好
Abstract:
According to the theory of composite material mechanics and the Kelvin model of theology, a model to describe the hydration of cement pastes an earlier stape is established. The premise of this model is that the shape of the Cement particles and hydration products is spherical and the pore structure shaped by the Cement paste is like the shape of hole. According to Linear theory and Elasticity theory, the effective elastic modulus at the time past and the degree of hydration increasing is also studied. Finally, with the rheological Kelvin model theory, the elastic modulus range equation of cement pastes is withdrawn. The results show that the model is applicable to describe elastic modulus variation about the initial setting of cement pastes and the variation and accuracy is in good agreement with the data of the literature
