An Experimental Study on Partial Replacement of Cement and Fine Aggregate with Industrial Waste in Concrete Paver Blocks

Abstract

The present experimental investigation reports the relative results of flexural and compressive strength of conventional uni-paver concrete blocks of M-40 grade with the paver blocks produced by the combined partial replacement of the cement and fine aggregate with fly ash and pond ash respectively. Incorporation of these industrial products resulted in the saving of cement subsequently an overall saving of about 10% in the economy per each paver block production, while not compromising with its performance in respect to its strength aspect. The paver block considered in this experimental work is of zig- zag shape specimen of size 201 mm × 100 mm × 80 mm. Initially, fine aggregate and cement were replaced in percentages of 5, 10, 15 and 20 separately with pond ash and fly ash respectively. Later on, both fine aggregate and cement were replaced and the performance of paver block is evaluated in terms of its mechanical properties.
