利用质量数据和回归分析法对混凝土配合比设计进行质量控制,是全面质量管理的具体工作内容之一,是保证建设工程质量的重要手段。在进行混凝土配合比试验中,混凝土抗压强度R与灰水比C/W之间的关系即R～C/W之间通常被看成直线关系,但在试验资料相当分散的情况下,或一般情况下,将试验点绘在 The use of quality data and regression analysis of concrete mix design quality control, is a comprehensive quality management of the specific content of one of the work is to ensure the quality of construction projects an important means. In the concrete mix test, the compressive strength of concrete R and gray water ratio C / W relationship between R ~ C / W is usually seen as a linear relationship, but the test data is quite decentralized, or Under normal circumstances, the test point painted in
