EPS保温砂浆性能试验研究
Experimental studies on the properties of EPS thermal insulating mortar
摘要
Abstract
In order to explain the effects of different components on the performance of expandable polystyrene (EPS) mortar, the influence of EPS volume fraction, glue, air entraining agent and fly ash content on the workability , strength properties, thermal conductivity, water absorption, and the softness coefficient of EPS thermal insulating mortar were experimentally studied. The experimental result indicates that high performance EPS thermal insulating mortar can be made by limiting the EPS volume fraction to 80% ~82% , air content to 20% or so, and fly ash content to 20%. The addition of poly vinyl acetate emulsion can improve the bonding strength and flexural strength of EPS mortar. In addition, some addition of fly ash can improve the drying shrinkage and thermal conductivity of EPS mortar, and therefore increase the comprehensive properties of the EPS thermal insulating mortar.关键词
