| Abstract: | Based on the optimization of raw material with optimizing proportion, adopting good powder of fine grinding slag, fly ash and silica fume as compound mineral admixture with high performance water reducing agent, using small percentage of water cement ration, C90 high-strength concrete may be manufactured successfully. It enjoys the following merits such as high fluidity in workability, small percentage loss of slump and early strength, and it adapts for the construction of high-rise, big-span and over loading buildings. |
