Abstract

This research aims to study the compressive strength of geopolymer pervious concrete. The mix proportions were prepared with alkali solution to fly ash (AS/FA) ratios of 0.75, 1 and 1.25 by weight. The water to fly ash (W/FA) ratios of 0.3 and fly ash to stone (FA/ST) ratios of 1:8, 1:10, 1:12, 1:14 and 1:16 by weight. Testing the compressive strength of geopolymer pervious concrete were cured for a period of 28 days at ambient temperature compared to geopolymer pervious concrete were curing temperature at 80 °C for 1 hour. Further testing the compressive strength of pervious concrete were use Portland cement equal to the weight amount of fly ash and alkali solution combined. The results revealed that the compressive strength of specimens were cured in oven was lower than that of specimens were cured at ambient temperature. Compressive strength and bulk density of geopolymer pervious concrete tends to increase with increase of fly ash. However compressive strength are decreased when increased amount of alkali solution in the mix. (AS/FA) ratio of 0.75 gave the highest compressive strength. Compressive strength and bulk density of pervious concrete tends to increase with increase Portland cement replacement.
