초록

The objective of this paper was to investigate experimentally the effect of aggregate kinds on the engineering properties of the ultra high strength concrete with 80 MPa. Granite stone(GA), low purity lime stone(RLA) and high siliceous lime stone(HSRLA) and basalt stone(BA) were used to make ultra high strength concrete incorporating silica fume and fly ash, respectively and water to binder ratio(W/B) was ranged from 15% to 30%. Test results showed that RLA, HSRLA and BA had favorable distribution of grain shape, which is higher than 58%. The use of RLA and HSRLA is achieved higher compressive strength than others due to improved elastic properties of RLA and HSRLA. More interestingly, the results of autogenous shrinkage was reduced remarkably when RLA and HSRLA were used compared with the results of GA. This is also due the formation of monocarboaluminate associated with $CaCO_3$ and $C_3A$.
