摘　　要：本实验对一种以高水速凝材料为基的低灰、低弹模混凝土的力学性能进行了研究。实验研究得出了不同配比下双低材料的抗压、抗弯强度和弹性模量 ,并与常规水泥混凝土、高水速凝材料进行了比较。In this paper,the mechanical performance of a new kind of concrete with low cement content and low elastic modulus is studied by experiments.Elastic modulus,compressive strength and bending strength are found.Comparing this material with 425# concrete,Its elastic modulus is lower 2 order than 425# concrete,bending strenght has the same order,and compressive strenght is lower 1 order only.The compressive strenght and bending strength of the material is 50～90% higher than high water fast hardening material.
