Open full text 15 citations

Abstract

Effect of aggregate grading on pervious concrete propertiesFresh and hardened pervious concrete properties are experimentally determined in the paper.The correlation between the compressive strength, flexural tensile strength, flow coefficient, and aggregate grading is analysed.As there is no approved method for determining the flow of water through pervious concrete, the testing was conducted in accordance with the already known methods, but using own apparatus.Optimum strength and flow capacity results were obtained on gap graded samples with the 0-2 mm sand content of less than 15 %.
