混凝土配制控制,混凝土采用常用山东预制叠合板设计等级混凝土施工配合比


NO.2:严把材料配制关,提高防渗施工质量

混凝土配制控制,混凝土采用常用山东预制叠合板设计等级混凝土施工配合比,但应将水灰比控制在0.38以下,砂率宜控制在45%-48%,通过加入高效减水剂调整用水量。混凝土具体搅拌步骤为:先加入石子、砂,开动搅拌机搅拌45秒;加入适量水泥、高效减水剂,搅拌90秒;缓慢加入水,搅拌120秒。为保障聚丙烯纤维分散均匀,先将聚丙烯纤维加入水中充分搅散,再加入搅拌筒搅拌,应控制搅拌总时间不少于240秒,在山东预制叠合板后浇混凝土配制过程中加入特定掺量的聚丙烯纤维、膨胀剂,各自的抗裂效应能互相补充,使混凝土的抗裂性能够得到较大改善。【具体可参考《预防山东预制叠合板裂纹问题,厂家自有妙招!》的相关内容】
