混凝土搅拌车是用来集中搅拌混凝土的联合装置,又称混凝土预制场。由于它的机械化、自动化程度较高,所以生产率也很高,并能保证混凝土的质量和节省水泥,常用于混凝土工程量大、工期长、工地集中的大、中型水利、电力、桥梁等工程。随着市政建设的发展,采用集中搅拌、提供商品混凝土的搅拌车具有很大的良好性,因而获得迅速发展,并为推广混凝土泵送施工,实现搅拌、输送、浇筑机械联合作业创造条件。
Concrete mixer truck is a combined device used for centralized mixing of concrete, also known as concrete prefabrication yard. Because of its high degree of mechanization and automation, it has high productivity, and can ensure the quality of concrete and save cement. It is often used in large and medium-sized water conservancy, electric power, bridge and other projects with large amount of concrete, long construction period and concentrated construction site. With the development of municipal construction, the mixer truck with centralized mixing and commercial concrete supply has great advantages, so it has developed rapidly, and creates conditions for promoting concrete pumping construction and realizing the joint operation of mixing, conveying and pouring machinery.

混凝土搅拌车主要是适用于各级的公路的基层的以及底层的,水泥的稳定中粒土和粗粒土用作基层时其水泥的计量不要超过百分之六。对于土的要求就是要比较易于破碎,要满足一定的级配,以便于碾压成型。
The concrete mixer truck is mainly suitable for the base course and bottom course of highways at all levels. When the cement stabilized medium grained soil and coarse grained soil are used as the base course, the cement measurement shall not exceed 6%. The requirement for soil is that it should be easy to be broken and meet certain gradation, so as to facilitate rolling forming.
细粒土要求:颗粒的的直径要小于9.5毫米,同时小于2.36mm的颗粒含量不小于百分之九十。
Requirements for fine-grained soil: the diameter of particles shall be less than 9.5mm, and the content of particles less than 2.36mm shall not be less than 90%.
中粒土要求:颗粒的的直径要小于26.3毫米,同时其中还要小于18.6毫米的颗粒含量不小于百分之九十。
Requirements for medium grained soil: the diameter of particles shall be less than 26.3mm, and the content of particles less than 18.6mm shall not be less than 90%.
粗粒土要求:颗粒的粒径小于37.5mm,且其中小于31.5mm的颗粒含量不小于百分之九十。
Coarse grained soil requirements: the particle size is less than 37.5mm, and the content of particles less than 31.5mm is not less than 90%.
