The construction of concrete pavement is growing across the country due to its strength, durability, better serviceability & overall economy in long run. The need is to develop better quality pavement sections, which can bear heavy loads. This can be achieved by using high compressive strength concrete (>40MPa) made up of hydraulic cement having fine & course aggregates. In the work embodied construction work is done with the help of wastage from industry. Fly ash is a by-product of burned coal from thermal plants and Rice husk ash is the by- product of burned rice husk from paper plant. Considerably Fly ash are used as supplementary cementing materials to improve the properties of cement concrete. The present study is done to develop pavement quality concrete by partially replacement cement with Fly Ash. The aim of study is to compare the strength characterizes of pavement concrete which as achieved by concrete mixtures. The work done in this study shows the effects on the behavior of concrete produced from cement with combination of FA at different proportions on the mechanical properties of concrete such as compressive strength, flexural strength. The replacement of cement were done at three levels is 10%, 20% and 30% with Fly ash as well as combination of both Fly ash and Rice husk ash. The tests on hardened concrete were destructive in nature which includes compressive test on cube for size (150 x 150 x 150 mm) at 7 and 28 days of curing as per IS: 516 1959, Flexural strength on beam (150 x 150 x700 mm) at 28 days of curing as per IS: 516 1959. The samples were prepared water-cement ratio of 0.40 for flexure design 4.5 MPa. The result so obtained showed that it is possible to achieve saving in cement if replacement is done.
