水泥是生产和建设中必需的重要物资,目前国家水泥的产量与需要之间缺口很大。今后随着社会主义现代化建设的发展,水泥的需要量将会越来越多,供应紧张的局面不可能在短期内缓和。为此,必须大力提倡节约水泥,杜绝浪费。混凝土及砂浆标号在施工中的超强,是目前施工工地浪费水泥的一个渊薮。这就要求施工人员严格按照施工技术设计的混凝土及砂浆标号与配合比施工,节约水泥用量。工地
Cement is an important material necessary for production and construction. At present, there is a large gap between national cement output and demand.

This requires construction workers to strictly follow the construction technology designed concrete and mortar markings and mix ratio construction, saving cement consumption. Site
