摘要
混凝土是一种脆性非均质的工程材料,其干缩机理比较复杂,其中毛细孔张力理论得到了学术界的普遍认可,本文以这一理论为基础,采用ANSYS有限元软件建立了混凝土毛细孔计算模型,对混凝土的干缩变形进行了模拟计算。从而近似地找出了混凝土干缩应变与毛细孔内液体表面张力、凹液面主曲率半径之间的关系。
Concrete is a brittle heterogeneity project material, the shrinkage mechanism of is complicated, in which the pores tension theory has been widely recognized among academic circles. This article, based on this theory and ANSYS finite dement software, concrete pores computation module is set up, and simulation calculation of concrete shrinkage deformation is made in order to find approximately the relation among the surface tension of concrete shrinkage, liquid in the pores and the principle radius curvature.
