摘要
介绍了粗骨料材质对混凝土弹性模量的影响,实验选择三大类四种常用粗骨料,分别测定材质硬度、弹性模量以及骨料的压碎值等参数;制作混凝土弹性模量试件测定其弹性模量;掌握了骨料材质对混凝土弹性模量的影响规律,为实际工程提供参考依据。
This paper introduces the influence of material of coarse aggregates on elastic modulus of concrete.Four kinds of common coarse aggregates in three categories are used to determine the parent rock hardness,elastic modulus,crushing value of aggregates and other basic parameters.Based on confecting concrete of different strength grades to make specimens of elastic modulus,and mastering the influence law of the aggregate material on elastic modulus of concrete,this paper will put forward the necessary reference for practical construction.
