摘　　要：为充分利用新疆地区农作物剩余物——棉花秸秆,提出一种墙体新型填充砌块——棉花秸秆砌块,介绍其配置工艺,并研究基本力学性能。通过正交试验设计配置满足填充材料强度要求的纯生态棉花秸秆砌块,进行单轴抗压试验,研究最佳配合比下砌块的基本力学性能,得到砌块的基本物理、力学性能参数,可用两个阶段描述砌块的单轴受压本构关系。此种材料可作为墙体填充材料,应用于工程实际是完全可行的。A new filled block wall-cotton straw block is proposed to take full advantage of the cotton straw in Xinjiang,the configuration process is described,and the basic mechanical prosperity is studied.The pure filler material eco-cotton straw blocks are deployed to meet the strength requirements by orthogonal experimental design,based on the optimum mix proportion,the basic mechanical properties of the blocks are studied by uniaxial compression tests,and the basic physical and mechanical performance parameters are obtained,the uniaxial compression constitutive relationship of the block can be described in two stages.This material,as wall filler material,used in engineering practice is entirely feasible.
