Abstract
Fly ash and waste polystyrene foam are two major killers of the environment. By turning waste into treasure, we use it rationally. This is a new way to develop new materials. The lime fly ash and gypsum were used as the activator of fly ash, and the modified polystyrene foam was added to develop a good insulation properties and durability of fly ash polystyrene insulation mortar and block. This is a new type of environmental protection and energy-saving insulation materials. It can be well adapted to the hot summer and cold winter climatic conditions, so as to meet the requirements of building energy efficiency. In this paper, the composition of raw materials, experimental ideas, technical means, hydration, hardening and other properties of the thermal insulation mortar block have been studied comprehensively and systematically.
