砌筑砂浆在土建工程中是一项工程数量相当大的工作,因而砂浆工程中的水泥用量,是不容忽视的。尤其在房建工程中,它的用量(包括白灰)是相当可观的。为此,我们在进行冬季室外冷砂浆试验研究时,本着节约水泥的原则,学习了兄弟单位的先进经验,试制了砂浆微沫剂,并设想把这种微沫剂用在标准养护、冬季低温室外养护及各种复合剂的对比试验中。在试验过程中,采用了正交试验设计,对微沫冷砂浆试验方案做
Masonry mortar is a considerable amount of work in civil engineering. Therefore, the amount of cement used in mortar projects cannot be ignored. Especially in building construction projects, its usage (including white ash) is considerable. To this end, during the winter cold mortar experimental study, we learned the advanced experience of our brothers in the principle of cement-saving cold mortar and trial-produced mortar micro-foaming agent. We envisaged the use of this micro-foam in standard maintenance and winter. Low-temperature outdoor curing and various combinations of agents in the comparative test. In the test process, an orthogonal test design was used to test the micro-foam cold mortar test program.
