Abstract：Based on the successful preparation of C100 ultra-high strength concrete,this paper systematically studied the in-fluence of stirring mode,mold material,specimen size,curing way and press range on concrete strength in indoor environment. The results show that:the mode of agitation mainly affected the workability of the concrete,but affected the strength little. The compres-sive strength of the steel mold was higher than that of the plastic mold,and the strength difference value increases with the size of the test piece. The conversion coefficient of the 100 mm cube specimen strength is 0.89,and the compressive strength decreases with the increase of the average size deviation of the specimen. 3 days 80℃ fast steaming can predict the strength of concrete for 28 days,when using a larger range of presses,the strength results have small discreteness.
