大掺量粉煤灰高性能混凝土的强度推测及正交试验线性分析

Strength Inference of High Performance Concrete with Large Volume Fly Ash and Proportional Analysis of Orthogonal Experiment

大掺量粉煤灰混凝土是具有广阔发展前景的绿色建材，本文采用线性回归分析法推定其砂浆24小时快测强度与56天实际混凝土强度关系式，通过混凝土配合比的正交试验，分析有关因素的影响效果，并确定了混凝土配合比的最优方案。

In this paper,the linear regression analysis me thod is used to infer the actual 56d compression strength of high volume fly ash concrete,one of green building materials with vast development foreground,by ac celerated test of 24h strength of mortar.The effect of related factors have been analyzed by the orthogonal experiment of concrete,and the optimized project of concrete proportion has been determined.
