Abstract

Pervious concrete made from geopolymer has some advantages over cementitious pervious concrete in strength as well as in abrasion. It also helps in reducing emission of carbon dioxide in environment. Metakaolin is used as a prime material to produce Pervious Geopolymer Concrete (PGC). In this study, nine different mixes are experimented to check its workability, porosity, permeability and compressive strength. Each mix has different proportion of alkaline liquid (AL) to binder (B) ratio (varying between 0.35, 0.40 and 0.45) and Sodium silicate (Na2SiO3) to Sodium hydroxide (NaOH) ratio (varying between 2.5, 2.0 and 1.5) and two different sizes of aggregates ere used, i.e., 4.75-10 mm and 10-20 mm. PGC is cured at elevated temperature of 60?C for 24 hours after casting. NaOH solution having 16M and Na2SiO3 are used as alkaline activators to produce PGC. Specimens are tested after 7 days and 28 days. Up to 21 MPa strength can be achieved with designed porosity range of 20-25%.
