EPS保温砂浆性能的影响因素分析

【摘要】 EPS保温砂浆是以聚苯乙烯泡沫(EPS)颗粒作为主要轻骨料配制而得 ,它节能利废 ,保温隔热性、抗裂性和耐候性优良 ,施工和易性好 ,可用于建筑外墙保温。其组成材料主要为 :水泥、聚苯乙烯泡沫颗粒、高分子粘结剂、纤维、膨胀珍珠岩及特细砂等。分析了EPS颗粒形貌、EPS粒径和级配、膨胀珍珠岩和特细砂、粘结剂品种和掺量、纤维品种和掺量、养护制度等对EPS保温砂浆性能的影响。更多还原

【Abstract】 EPS thermal insulation mortar is made from expanded polystyrene sheet (EPS) as main light aggregate. This mortar can save energy and utilize wastes with excellent thermal insulation, cracking resistance and weatherability, as well as good construction workability, which can be used for building exterior wall thermal insulation. Its main compositive materials are: cement, EPS, high molecule binder, fiber, expanded pearlite and super-fine sand. The influence of granula morphology, grain size and distribution of EPS, variety and added quantity of expanded pearlite, super fine sand, binder and fiber, curing system on EPS thermal insulation mortar properties are analyzed.更多还原
