SIGNIFICANT PHYSICAL AND MECHANICAL PROPERTIES OF GAP-GRADED CONCRETE

The results of an extensive investigation involving three hundred and seventy-five mixes of gap-graded and continuously graded concrete mixes in the strength range of 210 kg/cm2 to 530 kg/cm2 (3000 lb/in2 to 7500 lb/in2) with four different maximum sizes of coarse aggregate are presented in this paper. The water-cement ratios by weight of the mixes varied from 0.35 to 0.65, and the aggregate-cement ratios by weight from 2.0 to 10.0. Within the premises of this study, it is concluded that gap-graded concrete, though of a relatively stiffer and drier mix, can be placed and finished without undue effort for all construction work wherein continuously graded concrete has been customarily used heretofore. A considerable saving in cement content and notable improvements in physical and mechanical properties are the realistically achievable advantages through the use of gap-graded concrete for all purposes where conventional concrete is being used. /Author/TRRL/
