摘要
本文参考有关文献的早期推定混凝土强度方法,利用预拌混凝土原材料相对稳定和混凝土取样强度检测数据丰富的条件,根据线性回归方法,建立预拌混凝土搅拌站的混凝土强度发展经验公式,用以及时推定混凝土的7天、28天强度和及时确定施工配合比。
This article refers to literature about forecasting concrete early strength.By using relative stability of concrete material and plenty of data of inspecting concrete strength,a formula is built to forecast increase of concrete strength.So strength in7days and28days is forecast and mix ratio is determined.
