Title

POROUS CONCRETE & ITS CHARACTERISTICS WITH MINERAL ADMIXTURES

Authors

Abstract

The advantage of a pervious or porous concrete pavement is to allow the runoff water to its below layers effectively, this characteristic of the pavement is usually dependent on the pore size, geometry & connectivity of the materials. The functional benefits of porous pavements are improved wet-weather driving safety, reduced tire pavement noise and replenishing of groundwater supplies, Porous concrete is an eco friendly pavement is also known as a no fine aggregate or zero slump concrete. This paper presents a study in which the effects of aggregate gradations on the permeability and mechanical properties of pervious concrete were investigated. Concrete mix with aggregate gradation of 20mm & 10mm size with fly ash as an admixture are tested for 7 days & 28 days compressive & split tensile strength for obtaining the optimum gradation mix for the porosity level varying from 15 to 35% by keeping 0.35 as water cement ratio. It has been found that There is a reduction in percentage of porosity in the concrete mix with the increase of fly ash at a percentage of 15 & 25 percent of weight in concrete mix for all the specimens tested under 7 days & 28 days & also when the finer aggregate (Fly ash) to coarse aggregate ratio is increased up to 10 % & 20%, there is a considerable increase in compressive & split tensile strength of the concrete specimens. The efficiency of pervious concrete will depend on amount of porosity & co efficient of permeability of mix where the co efficient of permeability had been tested for 7 days & 28 days concrete specimens by allowing the water to flow inside the concrete specimens where as there is considerable variation of flow with respect to the concrete specimens which are tested by Darcy’s law of permeability

Key Words

Porous concrete, permeability, mix design, compressive strength, admixtures.
