STRENGTH COST ANALYSIS OF CONCRETE PAVING BLOCK USING FLY ASH AND SISAL FIBRE

The paver blocks are manufactured from plain concrete is a small element used for outdoor applications and flexible road surfaces. Depending upon the traffic intensity these are fabricated with various thicknesses, dimensions and shapes to meet with the requirement of various applications. This paper aims to develop paver blocks using fly ash and sisal fiber. In the present study M40 grade paver blocks with thickness 80mm with replacement of 43 grade OPC by 15%, 25%, 35% of fly ash and also replacement of OPC by 0.2%, 0.5%, 0.8% and 1.0% of sisal fiber. The blocks have been tested at the age 3, 7 and 14 days for strength and durability criteria. For strength properties compressive strength and flexural strength test were conducted, both being important for applications for road surfacing. Experimentation is carried out to find the compressive strength and flexural strength of the concrete paving blocks. Experimentation is also carried out analysis the production cost of concrete paving blocks by using fly ash and sisal fiber
