摘要:

水泥基材料在适宜的环境中养护成熟后其内部多余的自由水分会不断的挥发到空气中,材料也从饱和状态过渡到非饱和状态,其力学性质也相应的发生改变.首先通过物理实验研究水泥基材料在干燥过程中其主要力学性能的发展,然后建立损伤-弹塑性-干燥耦合模型来描述水泥基材料在不同的饱和度下的力学表现.模型计算的结果同实验数据的比较表明:所建立的模型能够很好的反映水泥基材料的力学性能在干燥过程中的变化.

Abstract:

After the cement-based material is cured and matured in a suitable environment, the excess free moisture inside it will continue to volatilize into the air, and the material will transition from a saturated state to an unsaturated state, and its mechanical properties will change accordingly. Firstly, the development of the main mechanical properties of cement-based materials in the drying process is studied through physical experiments, and then the damage-elastoplasticity-drying coupling model is established to describe the mechanical behavior of cement-based materials at different saturations. The comparison of the model calculation results with the experimental data shows that the established model can well reflect the changes of the mechanical properties of cement-based materials during the drying process.
