摘要
为考察碱矿渣陶粒混凝土砌块砌体的受压本构关系及基本力学性能,完成了126个用碱矿渣陶砂砂浆和碱矿渣陶粒混凝土砌块砌筑的砌体试件的轴心抗压试验。研究结果表明:当砌块抗压强度和砌筑砂浆抗压强度相同时,由于碱矿渣陶砂砂浆收缩大,该类砌体的峰值压应变、极限压应变均低于普通混凝土砌块砌体。建立了以砌体抗压强度、砌块抗压强度和砌筑砂浆抗压强度为自变量的这类新型砌体峰值压应变、极限压应变以及弹性模量计算公式。
In order to investigate the compressive constitutive relation and basic mechanical properties of alkali slag ceramsite concrete block masonry,the axial center resistance tests of 126 alkali slag ceramsite concrete block masonry specimens built with alkali slag pottery mortar were conducted.The results show that when the compressive strength of the block and the compressive strength of the mortar are the same,the peak compressive strain and ultimate compressive strain of the masonry are lower than those of the ordinary concrete block masonry because the shrinkage of alkali slag pottery mortar is large.Based on experimental results,the calculation formulas of peak compressive strain,ultimate compressive strain and elastic modulus of masonry are established with masonry compressive strength,block compressive strength and mortar compressive strength as independent variables.
