摘要
工业化生产砌块专用砌筑砂浆 ,有利于原材料质量控制、生产工序机械化和产品检验及质量保证 ,各种强度等级砂浆样品检测结果均符合标准要求。如Mb15砂浆7d强度14.8MPa ,28d强度达20.3MPa,经25次冻融试验 ,重量损失率1.0 % ,强度损失率仅7.1% ,并可减少施工现场浪费和污染环境 。
Mortar particularly designed for mass produced concrete blocks may facilitate raw material quality control, mechanized production, products test and quality securing. Test result shows that every gradation of all kinds of mortar samples met standard requirements. For example, 7 day strength of Mb15 mortar is 14.8 MPa, while 28 day strength is 20.3 MPa. After 25 times freezing-melting experiment it is found that mass and strength loss rate are respectively 1.0% and 7.1%. In addition, on-site waste is reduced, yet avoidance of environment pollution.
