摘要/Abstract

摘要： 以天然植物组织油茶粕为原料,通过水提法制备绿色发泡剂,并采用物理发泡方式制备泡沫混凝土,研究混泡时间、水胶比和泡沫掺量对泡沫混凝土干密度、抗压强度及孔结构的影响。结果表明:绿色发泡剂泡沫稳定性高,可用于制备低密度泡沫混凝土,是一种优质的新型绿色发泡剂;当泡沫掺量为750 mL、混泡时间为180 s、水胶比为0.45时,所制备的A05密度等级泡沫混凝土的吸水率为45%,抗压强度为1.52 MPa,并且绿色发泡剂制备的泡沫混凝土孔径分布均匀,孔径小(最大气孔孔径d_max＜0.6 mm),气孔形态完整。

Abstract: The green foaming agent was prepared by water extraction method with natural plant tissue camellia meal as raw material, and the foam concrete was prepared by physical foaming method. The effects of mixing time, water-binder ratio and foam content on the dry density, compressive strength and pore structure of foam concrete were investigated. The results show that the green foaming agent has high foam stability and can be used to prepare low-density foam concrete, so it is a high-quality new green foaming agent. When the foam content is 750 mL, the mixing time is 180 s, and the water-binder ratio is 0.45, the water absorption of the prepared A05 density grade foam concrete is 45%, and the compressive strength is 1.52 MPa. The foam concrete prepared by green foaming agent has uniform pore size distribution, small pore size (maximum pore size d_max<0.6 mm), and complete pore morphology.

Key words: camellia meal, green foaming agent, foam concrete, physical foaming, microscopic pore structure, pore size distribution
