Flexural Strength of ICBPs utilizing Waste Brick Kiln Dust as a Partial Replacement of Cement adding Waterproofing Superplasticizer as a Admixture

Now a day’s construction of Interlocking concrete block pavements( ICBPs) generally called paver block  is going to increase rapidly with very high rate due to having easy laying, consuming less time, easy in installation and mainly due to found in a lot of variety and shapes which gives better surface finishing and attractive look. Demand of ICBPs increasing day by day for different categories like Non-traffic, Light-traffic, Medium-traffic, Heavy-traffic and Very heavy-traffic and applications likes Building premises, monument premises, landscapes, public garden, parks, domestic drives, Pedestrian plazas, shopping complexes ramps, car parks, office driveways, housing colonies, office complexes, rural roads with low volume traffic, City streets, small and medium market roads, low volume roads etc. In this experimental study we considering flexural strength for M-35 grade of paver block with partial replacement of cement with brick kiln dust (B.K.D.) at six different percentages like 5 %, 10  %,  15  %,  20  %,  25  %  and  30  % and comparison with conventional  mix that is 0 % of replacement of cement also adding 2 % waterproofing superplasticizer by weight of cement added at 7, 14 and 28 days.
