混凝土搅拌效果良好与否主要由搅拌的方式、搅拌机的形状、搅拌叶片的形状及配置、进料方式、进料程序等而定。如何在最短的时间内生产合乎要求的混凝土,是一个重要的课题,因此,混凝土搅拌必须掌握下列原则: 1.水泥、添加剂、粗细骨料必须同时进入搅拌机中,也必须同时进料完毕。这样可使各种材料在进入搅拌机的每一瞬间保持配合重量的比例,使搅拌简易,提高搅拌效率,减少搅拌时间。2.约有10%的水量必须比其他材料提早及延迟进入搅拌机中。水必须比其他材料提早进入搅拌
The concrete mixing effect is good or not mainly depends on the stirring method, the shape of the mixer, the shape and configuration of the stirring blade, the feeding method, the feeding program, and the like. How to produce the required concrete in the shortest time is an important issue. Therefore, the concrete mixing must master the following principles: 1. The cement, additives, and coarse and fine aggregates must enter the mixer at the same time, and must also be fed at the same time. In this way, various materials can be kept in proportion to the weight of the mixer each time it enters the mixer, which makes it easy to stir, increase the mixing efficiency, and reduce the mixing time. 2. About 10% of the water must be brought into the mixer earlier and later than other materials. Water must enter the stirrer earlier than other materials
