高性能混凝土配合比设计正交试验研究

An Experimental Research on Mix Ratio of High Performance Concrete

运用正交试验设计法对高性能混凝土的配合比进行试验,研究了水泥、粉煤灰、矿渣和水胶比四个因素对高性能混凝土抗压强度的影响,找出了其中显著的影响因素。根据试验结果,进行线性回归,给出了预测模型。

This thesis analyzes the influences of the ratio of the components: fly ash, fine blast-furnace slag powderand W/C, in the mixture of cement, on the stress sustaining strength of high performance concrete. It identifies the mostinfluential factor in the analysis. It introduces that the experiments were implemented with orthogonal experimental methodsand a predication model has been worked out through the linear regression based on the results of the experiments.
