The rapid development of housing and infrastructure from last one decade continuously takes place in India. Along with that naturally, the product required to overcome this development produce in mass quantities like Pavement blocks, which are known as industrial products of precast made up by concrete, having various shapes and sizes utilizes in huge quantity in housing and infrastructure construction. The conventional materials to manufacturing these blocks utilize in large quantity, which may create an impact on natural recourses. To overcome this impact we can use different materials such as, Sisal fiber, waste glass, fly ash etc. which helps to save natural recourses and achieve economy so that buyers and sellers of this type of materials can also get benefited. The present experimental research investigation examines the effect of fly ash on the partial replacement of cement. Experiment is done on M33, M43 and M53 mix, with 5%, 10%, 15%, 20% & 25% partial replacement of cement. After getting an optimum percentage of all these, further experimental work is intended for the use of all these three in a single paving block. The replaced ingredients in this research are fly ash. Experimentation is carried out to find the workability test, water absorption test, compressive strength and flexural strength of the concrete paving blocks. Further, these studies compare an economical aspect of the conventional product and newly manufactured product.
