掺用聚丙烯纤维,即便是泵送或喷射混凝土,也不需要改变混凝土的配合比设计,且不需要特殊的设备或改变坍落度,只要确定两件事,即加多少纤维和使用纤维的长度。 1.搅拌纤维聚丙烯纤维系加工成小捆,使各捆都形成原纤维,这表明它们是由很多小纤维制成的。在搅拌作业中,骨料的移动使这 Blended with polypropylene fibers, even when pumping or spraying concrete, there is no need to change the mix design of the concrete, and no special equipment or slump changes are needed, as long as two things are determined, namely how much fiber is added and fiber is used length. 1. Stir Fiber Polypropylene fiber was processed into small bundles to form fibrils in each bundle, indicating that they were made from many small fibers. In the mixing operation, the movement of the aggregate makes this
