计算机在混凝土矿质混合料组成级配设计中的应用

当前的工程建设，质量与效率并重，施工单位目前在矿质混合料组成级配设计中广泛采用的图解法、试算法就暴露出烦琐、偏差大、效率低等缺陷。本文介绍了矿料级配设计的正规方程方法，同时应用Microsoft Office excel VBA工具进行二次应用开发，直接编程求解矿料组成配比，提高了矿料组成级配设计的效率和质量。

The Application of Computer in concrete mineral mixture proportion design

Quality and efficiency both play important role in the engineering construction. Curently, graphical method and calculation method which was widely used in the mix proportion design of mineral mixture had the defects of complexity, large deviation and low efficiency. Normal equation method of gradation design of mineral mixture was introduced in this paper. Microsoft Office excel VBA was applied to secondary application and exploitation. The mix proportion of mineral mixture was calculated by direct programming. And the quality and efficiency of gradation design was also increased.
