新型烧结页岩自保温砌块砌体受压性能研究

Compressive Behaviors of a New Self-insulation Sintered Shale Block Masonry

烧结页岩墙体材料属于绿色节能墙材,但竖孔类烧结墙体材料砌筑时砂浆易掉落孔洞中,影响建筑节能,而横孔墙体材料可以有效解决此类问题。研究了一种新型9排横孔烧结页岩自保温砌块砌体的抗压性能,通过两组(共12个)砌块砌体的轴心抗压试验研究,分析砌体在整个过程中受力性能和破坏机理,提出了此烧结页岩横孔砌块砌体抗压强度计算的建议公式。根据试验中砌体的应力-应变曲线,分析并拟合得出此砌体的对数模型的应力-应变计算关系式。本文的研究为此类砌块的工程应用和研究提供了理论依据和参考。

Sintered shale wall materials are energy-saving. But the sintered wall materials have vertical holesin masonry, as mortar falls into the holes, it will generate negative building energy saving effects. Wallmaterials with cross holes can effectively solve this problem. This paper deals with the compressive behaviorsof a new type of 9 horizontal-hole sintered shale self-insulation block masonry. Two sets of specimens （6 ineach set ） were tested. A new compressive strength formula was proposed by analyzing the mechanicalbehaviors and failure mechanism of this form of structures. The stress-strain formula for the new block masonrywas proposed by using a logarithmic function model. This study provides a theoretical basis to engineeringapplication of this new type of masonry.
