An evaluation of gap-graded concretes
Abstract
A study to compare the behavior of continuously-graded concretes to determine whether or not the gap-graded concrete mixtures were comparable to the continuously-graded concrete mixtures was described. The five factors investigated were: (1) coarse aggregate gradation; (2) water-cement ratio; (3) cement content; (4) fine aggregate content; and (5) length of curing. The fundamental material properties evaluated were compressive strength, modulus of elasticity, tensile strength, Poisson's ratio, and tensile strain, while the properties of the plastic concrete mix which were investigated included slump, density, air content, and workability.
