摘   要：自保温砌块是发展新型保温建筑材料的必然，对国内墙体材料的革新和节能技术的发展具有促进作用。本文所设计的自保温砌块，利用已处理的煤矸石进行制备，并使用热流计法对煤矸石保温砌块进行热工性能测试，测试结果表明：所设计240块型满足项目对传热系数的要求，同时利用软件模拟了砌块在真实使用环境条件下的温度场，砌块在使用时热应力集中区向围护结构的热环境偏移，这对建筑节能材料的设计、施工和检测具有指导意义。

Abstract: Self-thermal insulation block is necessary to develop a new type of thermal insulation building material, which promotes the innovation for domestic wall materials and energy saving technology. The self-thermal insulation block is prepared by handled coal gangue. The thermal performance of self-thermal insulation block with coal gangue is studied by using heat flow mater, the test shows that type 240# can meet the requirements of the heat transfer coefficient for project. Temperature field of self-thermal insulation brick is simulated under real environmental conditions by software, it can be seen concentration area of thermal stress shifts to hot environment of building envelope, which is a guiding significance for the design, construction and detection of building energy-saving materials.
