Utilizing and Optimizing Waste Resources in Paver Block

Use of concrete paver blocks in road pavements is more common nowadays. Concrete paver block is a better option in the road construction from the point of cost and better suitability, when compared to conventional road, which is made by bitumen and gravel. This paper is based on a project undertaken on utilization of coconut shells and waste paper sludge ash as inputs in manufacturing concrete paver block as replacement of coarse aggregate and cement, respectively. In the project, three sets of concrete paver block are proposed to be created on M40 design mix. The first set of paver block is the partial replacement of coarse aggregate by crushed coconut shells in the proportion of 0, 3, 6, 9, 12 and 15%. The second set of paver block is the partial replacement of cement by waste paper sludge ash in the proportion of 0, 3, 6, 9, 12 and 15%. The parameters will be tested regarding compressive strength behaviour of paver block specimens for 7 and 28 days. Based on the compressive value, the percentages of the coconut shell and waste paper sludge ash are combined to form a third set of paver block. This block is also to be checked for Compressive Strength, Water Absorption test, Abrasion Resistance test and Flexural Strength test.
