Experimental Research on the influence of Grain Size of Coarse Aggregate on Pebble Concrete Compressive Strength
To discuss the influence of coarse aggregate size,water cement ratio and ages on the concrete compressive strength,the compressive strength tests were carried out by 54 cubic specimens of pebbles concrete in dimensions of 150mm,18 cubic specimens with dimensions of 200mm and 72 specimens with size of 150mm×150mm×300mm.The results show that the maximum size of coarse aggregate rises with the decrease of the concrete compressive strength;Concrete compressive strength of coarse aggregate size affects more apparently as the ratio of water-cement decrease; with the increasing of age,concrete compressive strength of the aggregate size effect has no significant changes.
