Abstract

The mechanical character of natural Pebbles concrete and crushed stone concrete is studied in this study. The results show that compared with the aggregate concrete, the W/B can reduce the crushed stone concrete to a certain extent. For the C50 box beam concrete, the water cement will decrease by about 0.04-0.06. The density is adjusted according to the loose bulk density or the measured value of the aggregate. Under the condition of the same compressive strength, pebble concrete has similar flexural strength, axial compressive strength, elastic modulus to the crushed stone concrete. The tension and compression ratio of pebble concrete is lower than that of crushed stone concrete, and the compressive strength of pebble concrete is less than that of crushed stone concrete.
