A review and sequel experimental analysis on physical and mechanical properties of permeable concrete for pavement construction

Permeable concrete pavement is greatly beneficial and is required for parking lot and pedestrian walk in urban areas. Permeable concrete is a low density concrete that consists of more air voids which help in the infiltration of storm water. The present study, after examining many research works reviewed critically, proposes an enhanced permeable concrete with various mix proportions by conducting an experimental work. It involves conducting of compressive strength and permeability flow rate tests on permeable concrete with 1% of aluminium (Al) powder and 15% of Fly Ash (FA) by weight of cement as a partial replacement. In total, 18 cubes were cast and were grouped into two, such as permeable concrete with and without fine aggregate. The test results depict that the average compressive strength of permeable concrete using admixtures of 15% FA and 1% Al with and without fine aggregate is increased by 13.90% and 1.05% when compared with the corresponding control mixes, respectively. Permeability flow rate of the permeable concrete with and without fine aggregate is in the range of 7.67-9 ml/s and 14.83-15.83 ml/s, respectively. Scientific value of this research work recommends the type of permeable concrete and its applications based on its performance.
