Abstract :

There is growing interest in the construction of concrete pavements, due to its high strength, durability, better serviceability and overall economy in the long run. The thrust nowadays is to produce thinner and green pavement sections of better quality, which can carry the heavy loads. The high strength is a concrete having compressive strength greater than 40MPa, made of hydraulic cements and containing fine and coarse aggregates. The present study aims at, developing pavements quality concrete mixtures incorporating fly ash and rice husk ash partial replacement of cement. The aim is to the design of slab thickness of PQC pavement using the achieved flexural strength of the concrete mixtures. The work done in this study shows the effects on the behaviour of concrete produced from cement with combination of FA and RHA 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 both Fly ash & Rice husk ash as well as combination of both Fly ash and Rice husk ash. The samples were prepared with different water-cement ratio as 0.30, 0.35 & 0.40 for flexure design i.e. 5.5 MPa, 5.0 MPa& 4.5 MPa respectively. It is found that it is possible to achieve savings in the cement by replacing it with fly ash. This study also shows that in view of the high flexural strength, high values of compressive strength the 20% replacement of cement with fly ash is ideal for design of Pavement Quality Concrete (PQC).
