Evolution of Properties of Paver Blocks as per IS 15658 : 2006 using Rice Husk Ash and Nylon Fiber

Now a days paver blocks are widely used in India as well as in all over the world. Generally paver blocks are Solid, unreinforced, pre-cast and made up of cement concrete it is very attractive and at the same time cost-effective along with if it is manufactured and placed correctly, it requires no maintenance or very little maintenance. Paver blocks is categorized in in this different traffic categories as IS 15658: 2006 i.e. Non-traffic, Light-traffic, Medium-traffic, Heavy-traffic and Very heavy traffic. In this article we evaluate the properties of medium traffic paver blocks which is made up of M-40 grade concrete and of 80mm thickness. In this project nylon fiber is added in the concrete of paver blocks upto 0.5% by the weight of cement at an interval of 0.1%, after getting the optimum percentage for nylon fiber, in concrete of paver blocks cement is replaced by rice husk ash (RHA) in varying percentage of 10%, 20% and 30% and properties of paver blocks like compressive strength and flexural strength along with workability of the concrete are evaluated
