由于组成材料、试验条件和施工水平的差异,混凝土质量(以抗压强度为代表)常产生一定的波动。加强对混凝土的质量管理是施工部门极其重要的工作内容。采用微机进行质量管理,不仅节省大量人力,而且显著提高管理水平。混凝土的质量管理包括丰富的内容,本文仅介绍混凝土强度可疑值的舍弃、质量评定、强度频数直方图和施工质量控制图等程序的编写原理和方法。一、混混土强度舍疑程序对一定数量的混凝土强度样本进行统计,只有它们属于同一总体时才有意义。因此,在进行统计之前,首先必须把因非正常试验条件或过大的人为误差所造成的“反 Due to the difference of materials, testing conditions and construction level, the quality of concrete (represented by compressive strength) often causes some fluctuation. Strengthening the quality management of concrete is an extremely important part of the work in the construction sector. The use of computer quality management, not only saves a lot of manpower, but also significantly improve the management level. Concrete quality management includes a wealth of content, this article describes only the suspicious value of concrete abandonment, quality assessment, intensity frequency histogram and construction quality control procedures and other programs written principles and methods. First, the strength of the mixed soil suspicious process A certain number of concrete strength samples for statistics, only when they belong to the same overall makes sense. Therefore, before carrying out the statistics, we must first of all be caused by non-normal test conditions or excessive human error caused by "anti
