Abstract :

 Pervious concrete is a zero–slump, open graded material consisting of hydraulic cement, coarse aggregate, admixtures and water. Because pervious concrete contains little or no fine aggregates such as sand, it is sometimes referred to as “no–fines” concrete. It is a special type of concrete having a high void content of about 30%, is becoming popular nowadays due to its potential to reduce the runoff to the drainage systems which can provide a water flow rate around 0.34 cm/second. To achieve the porous concrete ordinary Portland cement is used. Herein this investigation the cement is replaced with silica fume in which ordinary Portland cement has been reduced by introducing silica fume as a cementitious agent. Compressive strength is carries out on hardened pervious concrete. This paper mainly focuses on the compressive strength of the pervious concrete. To investigate the compressive strength, “Cubes” of size 150mm x 150mm x 150mm are prepared and cured at a regular interval of 3,7,14 and 28 days, the specimens were tested I compression testing machine. Pervious concrete is made by replacing cement with silica fume to the extent of 10% by weight and strength tests were carried out. Different concrete mix proportions such as 1:4, 1:6 and 1:8 are prepared to the check the compressive strength of pervious concrete. The results indicate the pervious concrete containing 10% silica fume can achieve compressive strength of 17.0 N/mm2, 9.01 N/mm2, 6.32 N/ mm2 for the proportion of 1:4 , 1:6 and 1:8 for 28 days of curing respectively, whereas the strength of pervious concrete for normal PPC cement without mixing any admixture are 9.14 N/mm2, 5.92 N/mm2, 4.28 N/mm2 for 28 days of curing respectively
