【摘要】：为探索以物理发泡法制备兼具承重能力和保温功能的碱激发多孔材料,研究了泡沫掺量对碱激发多孔材料工作性能以及干密度、抗压强度和导热系数等关键性能的影响。结果表明:通过控制泡沫掺量制备的多孔碱激发材料干密度为628~1409 kg/m~3,抗压强度为2.18~22.01 MPa,导热系数为0.138~0.342 W/(m·K)。和物理发泡法制备的传统多孔混凝土相比,该材料强度和保温性能远优于相同干密度传统多孔混凝土,且工作性能优异,可用于自流平保温地面及其它传统泡沫混凝土应用的领域。
[Abstract]:In order to explore the physical foaming method to prepare alkali excited porous materials with both load-bearing capacity and heat preservation function, the working properties and dry density of alkali excited porous materials were studied by the amount of foam. The results show that the dry density of the porous alkali excited material prepared by controlling the content of foam is 62891409 kg/m~3. The compressive strength is 2.18 ~ 22.01 MPa and the thermal conductivity is 0.138 ~ 0.342 W / m 路K ~ (-1). It is compared with the traditional porous concrete prepared by physical foaming method. The strength and thermal insulation performance of this material is much better than that of traditional porous concrete with the same dry density, and its working performance is excellent. It can be used in the field of self-leveling thermal insulation ground and other traditional foam concrete applications.
