以改性胶粉聚苯颗粒为浇筑料，整体现浇，对拉螺栓紧固挤压成型的墙体，其质轻保温、隔声耐火，可有效降低劳动强度，提高施工效率。设计了抗压、抗折、抗拉、拉拔和弹性模量的试验。研究结果表明：气干状态下，材料的抗压强度随干密度降低呈指数衰减，与含水率并无规律可寻；材料的折压比、劈压比和弹性模量远大于同类型材料，材料韧性好，抵抗变形能力强；获得材料的极限拉拔力和拉拔强度指标，并对膨胀螺栓的选用及安装工艺作出说明；材料可做非承重内墙，结构节能一体化保温材料，复合到剪力墙、梁柱等热桥处，对工程材料应用具有一定的参考价值。

With modified powder polystyrene particles being used as integral cast in-situ pouring material ,the pulling fastening extru-sion bolted wall has the following advantages:light in weight,heat preservation,sound insulation,fire-proof,combined with effectively re-duce the labor intensity and enhance construction efficiency.However its material mechanical properties is unclear. Aim to provide neces-sary parameters and mechanical properties for its popularization and application ,the authors designed series experiments concerning the compressive strength,bending,tensile,pulling and elasticity modulus tests. Results showed that under the state of gas-dry ,the compressive strength of materials decrease exponentially with the the attenuation of dry density and were irrelevant to the moisture content. Material folding ratio,split ratio and elastic modulus were far greater than that of other materials. The material was characterized by good flexibili-ty,good unti-deformation performance.Limit drawing force and limit drawing strength index of the materials were obtained and then ex-plained the selection and installation process of expansion bolt.This kind of material can be used as interior nonbearing wall ,energy-saving integration of structure heat preservation material,compound to the shear wall,column and beam and other thermal bridge. It has certain value of reference for engineering materials applications.
