预拌混凝土作为基础建设的一种主要建筑材料,在我们的城市建设中发挥着至关重要的作用,但是预拌混凝土又与钢材、水泥等建材在运输使用上有着本质的不同。预拌混凝土作为一种半成品的建筑材料,影响混凝土强度质量的因素较多,不能单一地看待影响混凝土强度的原因。随着预拌混凝土的生产工艺日益完善,混凝土强度不达标的现象已大大减少;但也时有强度不达标的现象存在。根据笔者多年来的施工经验,主要从材料、生产运输、浇筑养护这几个方面谈 Ready-mixed concrete, as a kind of main building material for infrastructure, plays a crucial role in the construction of our city. However, the ready-mixed concrete is different from the transportation and use of steel, cement and other building materials. As a kind of semi-finished building materials, ready-mixed concrete has a lot of factors that affect the strength and quality of concrete. The reasons that affect the strength of concrete can not be seen in a single view. With the production process of ready-mixed concrete getting better and better, the phenomenon of substandard concrete strength has been greatly reduced; however, the phenomenon of non-compliance of strength sometimes occurs. According to the author’s construction experience over the years, mainly from the material, production and transportation, pouring conservation of these aspects
