降低泡沫混凝土吸水率的研究现状及展望

Status and Prospects of Research on Reducing the Water Absorption of Foamed Concrete

泡沫混凝土作为一种新型的无机保温材料,在各个领域得到广泛应用。但较高的吸水率是目前泡沫混凝土普遍存在的缺陷,严重影响了泡沫混凝土的耐久性和使用效果。本文结合近年来国内外在泡沫混凝土吸水率方面的研究情况,介绍了减水剂和防水剂在泡沫混凝土中的应用研究,指出了目前的研究中存在的不足,展望了降低泡沫混凝土吸水率的研究方向。

Foamed concrete is widely applied in various fields as a new type of inorganic heat preservation material. But the foamed concrete has higher bibulous rate, which seriously affect the durability performance of foamed concrete. According to the research of domestic and external, this paper introduced the application performance of waterproofing agent and water reducing agent on foamed concrete, and the insufficient in the current study were pointed out. The paper also proposed the research direction and development proposals to reduce water absorption.
