当前,我国建筑工程中60%以上的建筑物仍沿用砖、砌块等墙体材料,长期以来都存在着空鼓、爆花、裂缝、龟裂等通病问题。因此,如何提高和稳定建筑砂浆的质量、改善施工操作条件是建筑施工中亟待研究解决的现实问题。早在上世纪40~50年代至本世纪初,社会有识之士不断研发改进砂浆外加剂,研发的产品五花八门,层出不穷,虽然在一定程度上提高了建筑行业的施工速 At present, more than 60% of the building construction in our country still uses brick, block and other wall materials. There have been common problems such as hollowing, popping, cracks and cracking for a long time. Therefore, how to improve and stabilize the quality of construction mortar and improve the construction operation conditions are the realistic problems to be solved urgently in construction. As early as the last century, 40-50 years to the beginning of this century, people of insight continue to develop and improve the mortar admixture, R & D products varied, after another, although to some extent improve the construction industry construction speed
