Abstract
The pervious concrete is produced by using conventional cementitious materials, aggregates and water. In the present work pervious concrete is studied for its mix proportioning to study its various properties, such as cube compressive strength, split tensile strength, flexural strength and water permeability. The objective of the present study is to investigate the effect size of coarse aggregate, fine aggregate content, cement content and water cement ratio on the engineering properties of pervious concrete. Compressive strength tests were carried out in accordance with standard procedures, and specimens of pervious concrete were made using mix designs that were developed from the experimental design. The parameters of variation are size of coarse aggregates i.e. 10mm and 20mm (graded), w/c ratio i.e. 0.35 to 0.4, cement content i.e. 400 to 450kg/m3, fine aggregate content i.e. 0%, 5% and 10% by total weight of aggregates and cement: coarse aggregate ratio is maintained 1:4. To determine the possible interactions between the factors and determine the importance of each one, statistical analysis, including Analysis of Variance (ANOVA), was performed on the gathered data. The results show that several elements have a considerable impact on compressive strength, which can be used to optimize mix designs and reach the necessary strength levels. This study advances our knowledge of pervious concrete technology and provides useful advice for using it in building projects when certain compressive strength standards must be met.
