Experimental Research on the Influence of Pebble

By changing the grading of pebble and water cement ratio, the influence of pebble grading on the compressive strength and flexural strength of concrete is studied at the same pebble content. Test results show that the compression strength and bending strength of concrete decrease with the increasing of the maximal size of coarse aggregate, while the maximal size (Dmax) of pebble aggregate ...
