发泡聚苯乙烯增强泡沫混凝土的稳定性和力学性能研究
Study on Stability and Mechanical Properties of Foam Concrete Reinforced by Expanded Polystyrene
将不同颗粒的发泡聚苯乙烯(EPS)加入泡沫混凝土,研究EPS填充型泡沫混凝土复合材料的性能。结果表明:相较大颗粒EPS,掺入小颗粒EPS,泡沫混凝土的表观密度和吸水率降低幅度更大,气孔孔隙率增加幅度更高,且抗折强度和抗压强度降低幅度较小,导热系数降低更多,延缓泡沫混凝土的干燥收缩。在小颗粒EPS质量分数量为3%时,表观密度为463 kg/m3,孔隙率为63%,较空白组增加43.18%,抗折强度和抗压强度高达2.43 MPa和7.1 MPa,导热系数为0.108 1 W/(m·K),表明适量掺入小颗粒EPS有效提升了泡沫混凝土的稳定性和力学性能。
The properties of foam concrete composites filled with different particle size expanded polystyrene (EPS) were studied. The results show that compared with large particles of EPS, the addition of small particles of EPS results in a greater reduction in the apparent density and water absorption of foam concrete, a greater increase in the porosity of pores, a smaller reduction in the flexural strength and compressive strength, and a greater reduction in the thermal conductivity. The drying shrinkage of foam concrete is delayed. When the mass fraction of small particles EPS is 3%, the apparent density is 463 kg/m3, the porosity is 63%, which is 43.18% more than the blank group. The flexural strength and compressive strength are up to 2.43 MPa and 7.1 MPa, and the thermal conductivity is 0.108 1 W/(m·K), indicating that the proper amount of small particles EPS can effectively improve the stability and mechanical properties of foam concrete.
