台山混凝土道路工程全长671.5m,总面积40m~2,混凝土路面为C_(30),厚20cm,混凝土用量达1495m~3,该工程特点是工期紧、投资紧、质量要求高,而质量的优劣主要取决于混凝土的施工质量。浇捣混凝土,工地上传统的施工方法是一次投料法,是将混凝土拌合物一起投入搅拌机内进行搅拌,水泥颗粒被砂石夹裹着进入搅拌机内,遇水后很快形成水泥团粒,这种水泥颗粒夹在粗骨料中,粗骨料的粒径越大,水泥团粒越不易破坏,特别是当搅拌机搅拌时,处于搅拌机叶片背面的水泥团粒被有效地保护起来,粒径比水泥团粒大得多,成了水泥团粒的屏障,这一部
The Taishan concrete road project has a total length of 671.5m, a total area of 40m~2, a concrete pavement of C_(30), a thickness of 20cm, and concrete usage of 1495m~3. This project is characterized by tight schedule, tight investment, high quality requirements, and high quality. The merit depends mainly on the construction quality of the concrete. Concrete pouring, the traditional construction method on the construction site is one-time feeding method. The concrete mixture is put into the mixer and mixed together. The cement particles are wrapped in the sand and enter the mixer. The cement aggregates are formed soon after encountering water. The cement particles are trapped in the coarse aggregate. The larger the size of the coarse aggregate, the less likely it is that the cement pellets will break. Especially when the mixer is stirring, the cement pellets on the back of the mixer blades are effectively protected and the particle size is smaller than that of the cement pellets. Much bigger, becoming a barrier to cement pellets, this one
