摘要
泡沫的稳定性是决定泡沫混凝土综合性能的关键因素。然而,普通泡沫的泡径不均匀、稳定性较差,易发生聚结、歧化现象,产生大尺寸连通孔,造成泡沫混凝土物理力学、保温隔声性能下降。对近年来泡沫混凝土中泡沫的相关研究进行了全面阐述,主要聚焦于泡沫的制备、泡沫失稳机制、稳泡机理和措施3个方面。
Stability of foam is one of key factors to determine the comprehensive performance of foamed concrete.However,it is easy to cause coalescence and disproportionation of foams due to the uneven bubble diameter and poor stability of ordinary foam.As a result,the presence of large-sized connected holes will reduce the physical mechanics,thermal insulation and sound insulation properties of foamed concrete.In this review,recent studies on foam in foamed concrete were represented,focusing on three aspects,i.e.,foam preparation,foam instability mechanism,bubble stabilization mechanism and measurement.
