Analysis and Comparison on Mechanical Properties between Full-Graded and Wet-Screened Concretes
Based on typical hydraulic engineering, difference of performances between full-graded and wet-screened concrete was studied. Results showed that owing to the gradation effect and skeleton effect of coarse aggregate and the size effect of specimen, full-graded concrete was 105%, 75%, 65% and 115% in compressive strength, splitting tensile strength, ultimate tension and compressive elastic modulus respectively, compared with wet-screened concrete. Under the same curing condition, compressive strength of wet-screened standard concrete specimen can represent the actual compressive strength of full-graded concrete.
