摘要
弹性模量是混凝土重要的力学性能之一,是计算混凝土结构的应力、变形和大体积混凝土的温度应力所必需的参数之一。在试验分析的基础上,研究粉煤灰掺合料、龄期及强度对混凝土弹性模量的影响,并拟合出公式。
Elastic modulus is one of the important mechanical properties of concrete.It is essential to structural calculation of stress,deformation and mass concrete temperature stress.Based on the experimental research,the paper studies the influence of fly ash admixture,age and concrete strenght to the elastic modulus,and fits out the formula.
