| 摘 要： | 系统测试聚苯乙烯掺量对石渣粉混凝土干表观密度、28 d抗压强度和传热系数的影响程度和规律,以及其砌块和墙体的相关物理、力学和热工性能.试验数据表明,掺加聚苯乙烯在一定程度上降低了石渣粉混凝土干表观密度和传热系数,但28 d抗压强度有较大幅度降低.通过改变成型工艺和调整配合比,与基准砌块相比,掺聚苯乙烯的石渣粉混凝土空心砌块强度可增大,墙体传热系数K≤2.0 W·(m2·K)-1,可满足夏热冬暖地区节能50%的要求.当单掺聚苯乙烯时,可在一定程度上降低混凝土的导热系数,从而提高空心砌块壁肋的热阻,降低砌块墙体的传热系数,但砌块墙体传热系数降低幅度不大,需进一步采取其他配套措施.

| Abstract: | The influence of the polystyrene content on the dry apparent density,compressive strength of 28 d and heat conductivity coefficient,is investigated systematically.The physical,mechanical and thermal properties of hollow block and block wall are also tested.The experimental results demonstrate: incorporating the polystyrene,the apparent density and heat conductivity coefficient of the stone slag powder concrete decrease,the compressive strength of 28 d decreases greatly.The compressive strength of stone slag... |
