摘要
Abstract
In the light of the existing problem of concrete durability, 9 groups of mortar mixing ratio experiments were carried out through orthogonal design. The effects of carbonization time, freeze-thaw times, water-binder ratio and different dosages of fly ash on mortar compressive strength of 90 days were analyzed by range analysis and interactions. The experimental result shows that the test times can be reduced significantly and more test information can be provided by using orthogonal design. And in the 4 influencing factors, the carbonization time has the largest impact on mortar strength.关键词
