秸秆混凝土砌块的力学性能试验研究

Mechanical Property Testing of Straw Concrete Block

秸秆混凝土砌块是一种新型的环保节能建筑材料。通过对秸秆掺量为10%和15%的秸秆混凝土砌块进行轴心抗压强度试验,观察砌块的破坏过程和破坏形态,发现其与普通混凝土砌块相似。根据数据分析得出秸秆混凝土砌块的抗压强度和弹性模量,并用拟合公式对试验数据进行了对比,得到秸秆混凝土砌块的本构关系全曲线,以说明秸秆混凝土砌块的力学性能。

The straw concrete block is a new kind of environmental protection and energy saving materials. Through the axial compressive strength test of two straw contents at 10% and 15% of straw concrete block, and observation on the failure process and failure pattern, we found it＇s similar to ordinary concrete. According to the data analysis, the compressive strength and elastic modulus of straw concrete block are concluded; comparing the fitting empirical formulas with the experimental data, the constitutive relation curves of straw concrete block is gained to explain mechanical property of straw concrete block.
