Abstract
As a new building material, sintered coal gangue self-insulation block can not only make efficient use of industrial waste but also have a stronger heat preservation effect. In this paper, we use sintered coal gangue self-insulation block with staggered rectangle holes and wall as objects which can be seen commonly in the Anhui market. Through studying block type, wall thickness and masonry mortar type's effects on the heat preservation of the wall based on ANSYS numerical modeling, it proves that with special masonry mortar, sintered coal gangue self-insulation block can reach the best energy-saving effect, which meets the need of green building and sustainable building .
Highlights
With the increase of national requirements in energy saving and emission reduction, the development of building insulation material and the study in thermal performance are attached great importance

Gangue is one of the salvaged materials in coal mining in our country, which is regarded as cost-effective material for it can be used as both raw material and fuel in producing building materials and for it can keep active after burning
Summary
With the increase of national requirements in energy saving and emission reduction, the development of building insulation material and the study in thermal performance are attached great importance. By using the gangue as raw material to produce sintered self-insulation hollow block can improve the whole capability of block. Li Ping gained the conclusion that the sintered coal gangue masonry wall meet the national energy conservation requirement of saving 65% resource from the thermal performance testing in sintered coal gangue self-insulation block [1]. Ammar Bouchair established a theoretical model for simulating the thermal performance of the hollow brick, and he carried out the steady-state thermal analysis of the sintered hollow brick wall; The study shows that increase the hole length of the sintered hollow brick, add adiabatic insulation material in the slot, and reduce the radiation rate on the surface of the hole can improve the thermal performance of brick. We discuss the most energy-saving thermal insulation material collocation method through the numerical simulation and comparison of the insulation effect of sintered coal gangue self-insulation block and ordinary clay block as well as walls with different masonry mortar or different thickness
