混凝土质量控制是混凝土质量管理的一个程序。按照现代的生产管理方法,混凝土质量管理包括以下三个内容: 1.初步控制 指在施工前的原材料(包括砂石级配、含水率)检验;混凝土(包括水灰比、配合比、坍落度、含气量)试验;计量工具校核和施工机具检查等。 2.混凝土质量控制 指在施工过程中的控制,使混凝土具有稳定的质量。一般用抽样方式进行检查,并绘制施工质量控制图(管理图)进行管理,合理调整施工配制强度。
Concrete quality control is a procedure for quality management of concrete. In accordance with modern production management methods, concrete quality management includes the following three aspects: 1. Preliminary control refers to the inspection of raw materials (including gravel gradation and moisture content) before construction; concrete (including water-cement ratio, mix ratio, and fall) Degree, gas content) test; measurement tool verification and construction equipment inspection. 2. Concrete quality control Refers to the control during the construction process, so that the concrete has a stable quality. Sampling methods are generally used for inspection, and construction quality control plans (management maps) are prepared for management, and the construction preparation intensity is reasonably adjusted.
