免烧高掺量粉煤灰砖砌体受剪性能的试验研究

摘要

Based on the shear tests of 30 brick masonry made by non-steam high percentage fly-ash,the paper discusses the developing feature of shear bearing capacity and provides equation of shearing strength of fly-ash brick masonry. The result show shearing strength of fly-ash brick masonry is higher than normal brick masonry, suggested equation isf, = 0. 37f, n, which can provide reference for compile and revise the standard of wall materials in China.%通过对30个免烧非蒸压高掺量粉煤灰砖砌体的抗剪试验,分析了粉煤灰砖砌体的受剪承载力特点及其变化规律,给出了粉煤灰砌体抗剪强度的建议公式.计算结果表明,免烧结粉煤灰砖砌体的抗剪强度高于普通粘土砖设计值,设计值的建议公式为fv=0.37fv,m.本试验的研究,可为我国墙体材料标准的编制和修订提供依据.
