CSG材料强度特性及弹性模量的研究

Research on strength characteristics and modulus of elasticity of CSG material

研究了单位水泥量、养护时间对CSG材料强度的影响及相互之间的关系,并通过单轴抗压实验,探究了CSG材料的强度变化特性,实验结果表明,在最大粒径为80 mm、最长养护时间为28 d的条件下,CSG的单轴抗压强度随着养护时间和单位水泥量线型增加,且得出了单位水泥量对CSG材料弹性模量影响的相关关系式。

This work aims at studing the stress-strain-strength behavior of an CSG（ Cemented Sand and Gravel） materials. An analysis of the mechanical behavior of the CSG is performed from the interpretation of results by unconfined compression test in which the influence of both the degree of cementation and age. The experimental results show that the curing time of the maximum diameter is 80 mm,for 28 days,under the condition of uniaxial compressive strength as the curing time of CSG and linear increase unit cement amount,and unit cement quantity to the influence of the elastic modulus of CSG material related relation.
