盲孔多孔砖及其砌体物理力学性能的试验研究

The experimental research for blind perforated bricks and its brickwork' s physicomechanical properties

本文为陕西省建设厅所列研究课题,于2003年4月通过省级鉴定。研究结果表明,盲孔多孔砖及其墙片的绝热性能优于KP1多孔砖:盲孔多孔砖砌体的抗压强度能够满足规范要求,弹性模量与其他多孔砖砌体相当,高于实心黏土砖的弹性模量;但砌体的通缝抗剪强度略低于规范计算值.为保证结构安全,建议设计时乘以系数0.9。

blind perforated bricks and its brickwork' s physic mechanical properties were mainly researched in this article. Research results showed that blind perforated bricks and its brickwork' s heat insulation property were better than KPI perforated brick; the compression strength of its brickwork can meet the criterion requirement, its elasticity modulus were comparable to other perforated brickwork and higher than solid clay brick, but its brickwork' s shearing strength was lower than criterion calculation value, so the author suggested that shearing strength should multiply 0.9 in design in order to ensure the structure safety.
