我处承建的某工程,系多层高级民用建筑,装饰工程任务很大,仅抹灰工程一项就有100000平方米以上,工地现场狭窄,无法开挖淋灰池,再加上工期短,任务急,给大量石灰进场堆放、淋洗熟化和供应带来很大困难。为给施工创造条件,解决石灰膏供不应求的问题,同时降低成本和改善砂浆性能,我们在学习外单位有关资料的基础上,从1980年6月起,对以微沫剂代替生石灰拌制 The project I was contracted for was a multi-storey high-grade civil building. The task of decoration is very heavy. Only one plastering project has more than 100,000 square meters. The construction site is narrow and the ashing pool cannot be excavated, and the construction period is short. The urgency of the task made it difficult to put a large amount of lime into the yard for storage, rinsing, ripening, and supply. In order to create conditions for construction, solve the problem of shortage of lime paste, reduce costs and improve the performance of mortar, on the basis of the study of relevant data of foreign organizations, we have adopted the micro-foam agent instead of lime for foundations since June 1980.
