C70水泥混凝土弹性模量试验研究

Experimental Study of Elastic Modulus of C70 Cement Concrete

结合工程实例对C70混凝土弹性模量进行了试验研究,分析了混凝土配合比设计阶段、工字梁预制阶段的弹性模量的变化规律,探讨了同条件养护试件弹性模量和工字梁实体弹性模量的关系、工字梁放张时的弹性模量与同条件养护试件抗压强度的关系。

Based on the engineering practice, the elastic modulus of C70 concrete was experimentally studied. The change rule of elastic modulus at the stages of concrete proportioning design and I-beam precast was analyzed. The relationship of the elastic modulus between the curing specimen under the same condition and the solid I-beam, and the relationship between the elastic modulus of I-beam and the compressive strength of curing specimen under the same condition were discussed.
