Study on Different Diameter Porous Steel Slag to Early Cracking Resistance of Concrete by Internal Curing LIU Pan1,a,SHI Kebin1,b, ZHANG Linlin1,c 1College of Civil and Hydraulic Engineering, Xinjiang Agricultural University, Urumqi 830052,China a272851706@qq.com, bxndsg@sina.com (Corresponding author),c814334684@qq.com Key words: porous steel slag; internal curing; concrete; the knife-edge method; early crack resistance Abstract.
Introduction It is very difficult to meet the appropriate execution conditions in winter of the western area, especially the execution conditions of concrete engineering.
These cracks not only affect the appearance, but the durability of the concrete construction even the service life of the concrete engineering.
Also, they had achieved fruitful results and provided a reference for the improvement of concrete’s anti cracking performance in the practical engineering.

A lot of problems in engineering are unable to obtain accurate explicit analytical function relationship, such as the stability coefficient (SC) of excavation, so this sort of algorithm has a good adaptability.
Each of the error rates are less than 5% and can meet the requirements of engineer.
