Abstract – Utilization of concrete paver block is considered highly advantageous due to its property and it is used on large scale in our surrounding. The research on recycled construction material helps environmental by reducing the carbon content, depletion of natural resources, these wastes need huge land for disposal leads to the land disposal. Though. Disposal of waste is a necessary issue in recent time. According to the survey, In India, fly ash production was about 226.13 million tons in the year 201920 and it is predicted to be around 300-400 million tons by the year 2025 In this experimental investigation, the process of the development of the concrete for strength aspects in various proportions varying from 20%, 30%, 40% replacement of cement along with fly ash and marble dust with fine aggregate each. We are going to find its impact on compressive strength and identify the optimum percentage of replacement to gain the maximum strength and compare it with the strength of ordinary M30 grade of concrete. In this experimental investigation various test on aggregate cement and fresh concrete is carried out and analyzed. Compressive test is conducted on rectangular brick,the results are analyzed with respect to the IS-code

Image -1 Fly ash utilization In the case of road construction use of paver blocks helps us where rapid construction is needed. By increasing the quality and thickness of block we can use the paver block on heavy traffic road as well. Use of paver block is also beneficial where regular underground repair and maintenance needed.
Key Words: Fly-ash, Marble Dust, Concrete paver block,
Fly ash-based Bricks / Blocks / Tiles are as good as claybased conventional building products. It has great potential of fly ash utilization. A graph showing progressive utilization of fly ash in making of fly ash-based building products for the period from 1998-99 to 2020-21 is given in chart 1
1. INTRODUCTION As per the report of central electricity authority thermal civil design division new Delhi. Report on fly ash generation at coal / lignite based thermal power stations and its utilization in the country for the year 2020 – 21. Stated the following data and graphs. During the Year 2020-21, the maximum utilization of fly ash to the extent of 25.81 % of total fly ash generated was in the Cement sector, followed by 15.59 % in Reclamation of Low-lying area, 15.04 % in Roads & Flyovers, 12.98 % in Bricks & Tiles, 7.94 % in Ash Dyke Raising, 6.20 % in Mine Filling, 0.83 % in Concrete, 0.03 % in Agriculture,
