Experimental Study on Pervious Concrete with Silicafume as Cement Replacement
Permeable concrete is such a concrete in which the void ratio is suitably increased such that the structural member allows water to percolate it through, making the water, which is supposed to get lost as run off, percolate to the immediate ground. The voids are affected by many factors such as size and quantity of aggregates, amount of fine particles in the concrete, changing the porosity while designing the concrete etc. The modern concepts of structural engineering promoted the use of alternative materials as replacement cement as well as natural aggregate. Present study focuses on the effect of silica fume as replacement for cement in pervious concrete. Different porosities (8, 10, 12%) were considered to find out the nominal mix. The mix with highest strength value is selected as the nominal mix. The cement content in the nominal mix is then replaced with silica fume for 3, 4, 5, 6, 7%. Based on the strength results obtained, the optimum mix of silica fume based pervious concrete is selected. Cement can be replaced with 5% of silica fume for effective strength gain.
