泡沫混凝土的应用及其进展

Application and Development of Foam Concrete

泡沫混凝土是一种以无机胶凝材料为主,通过掺加泡沫形成气孔结构的轻质多孔材料。泡沫混凝土作为保温以及回填材料,可以起到很好的保温隔热作用,同时还可以降低工程成本,并可利用部分工业废料。泡沫混凝土在土木工程和建筑节能领域应用潜力巨大,可以较好地解决我国保温材料防火问题,并取得一定的经济效益。目前,国内外学者已对泡沫混凝土的生产工艺、组成成分改良、性能预测模型等方面进行了较为深入的研究,取得了许多成果。但是,在强度、稳定性、耐久性和性能均衡等方面都还有待进一步研究提升。

Foam concrete is a kind of light porous material,which is mainly composed of inorganic cementitious materials and forms porous structure by adding foam.Foam concrete as thermal insulation and backfilling materials can play a good role in thermal insulation,but also can reduce engineering costs,and can use part of industrial waste.Foam concrete has great potential in the field of civil engineering and building energy saving.It can solve the problem of fire prevention of thermal insulation materials in China and obtain certain economic benefits.At present,scholars at home and abroad have carried out in-depth research on foam concrete production technology,composition improvement,performance prediction model and other aspects,and achieved many results.However,the strength,stability,durability and performance balance need to be further studied and improved.
