A study on properties of pervious concrete with high-volume usage of supplementary cementitious materials as substitutes for cement

Pervious concrete has gained research interest due to its eco-friendly system and hydrological benefits.

Abstract

Pervious concrete has gained research interest due to its eco-friendly system and hydrological benefits. With sustainability in view, several researchers tried to employ alternatives such as Supplementary Cementitious Materials (SCMs) in concrete. However, studies on employing high-volume SCMs as cement replacement in pervious concrete are scanty. Thus, the present study is initiated to evaluate the properties of pervious concrete by incorporating a high-volume of fly ash, silica fume, and Granulated Blast-Furnace Slag (GGBS) as a partial replacement for cement. The high-volume replacement accounts for a replacement percentage of 20%, 35%, and 50%. Further, at a high-volume replacement of SCMs, it is hypothesized that the unreacted SCMs in the concrete mixture will act as fine aggregate and induce positive effects on the mix. The study evaluates the properties of pervious concrete, including compressive strength, flexural strength, porosity, permeability, Young's modulus, and Poisson’s ratio. With increasing the SCMs’ content in the pervious concrete, the compressive strength is observed to decrease significantly compared to the strength of the control mix. However, at all replacement percentages, the compressive strength of pervious concrete is observed to be higher than the desired strength. The influence of unreacted SCMs at high-volume replacement is evident in all the properties evaluated. Further empirical models are also developed for the properties assessed in the study to understand the quantitative comparisons between different design conditions of Pervious Concrete (PC).
