混凝土蛋白质发泡剂的改性研究

Study on Modification of Protein Foaming Agent for Concrete

简单介绍了发泡剂的发泡特性及泡沫稳定机理,并介绍了本文采用的基础蛋白质发泡剂的主要性质。在此基础上,选取了改善蛋白质发泡剂泡沫稳定性的几种化学物质。实验结果表明,茶皂素和蔗糖对发泡剂的发泡过程和泡沫稳定性均有不同程度的改善作用。其中茶皂素改善作用较明显,当其在发泡液中掺量为0.3g/L时,100mL发泡液的发泡体积为740mL,泡沫稳定时间在28h以上。

The foamability and mechanism of foam stability for foaming agent were introduced briefly and some additives to protein foaming agent for improving foam stability were selected in tests and discussed. The results show that two addtives can improve the foam stability of the agent to a different extents. Among which the saponin had more effective. When the dosage is in 0.3g/L, the foam volume with 100ml foaming agent is up to 740mL, and the foam retaining duration exceeds 28hrs.
