In developing country like India, the growth of population is increasing day by day and as a civil engineer it is our duty to provide the facility with minimum cost and maximum output. Paver blocks are the better replacement for the pavement where concrete or bitumen pavements are less durable due to large use of the pavement. Paver blocks also increases the aesthetic view of the area, can be easily laid and have better finishing property. The main problem arises with paver blocks are that in rainy season the water logging creates problem. Since the concrete paver block is not porous so water gets collected on the surface and there is no way for passage of water other than providing slope. To solve this problem porous concrete paver block is prepared with the help of locally available materials and fly ash. Porous concrete paver block will reduce the problem of water logging in rainy season and the use of fly ash and coconut fibre will increase its strength considerably. Coconut fibre is also helpful in reducing the cracks of paver blocks. Porous concrete paver block is also helpful in reducing the mixing of surface waste to surface water. Maintenance cost of paver block pavement is considerably low as compared to concrete or asphalt pavement. In modern days the use of steel in construction is increasing day by day and by using the fibers we can get the desired flexural strength. Various proportions of cement, sand, coconut fibre & fly ash are used to examine the properties of porous concrete paver block. In this study various properties such as compressive strength, split tensile strength & water absorption test was carried out between porous concrete paver and concrete paver. The porous concrete paver block is economical as compared with conventional paver block. Water absorption test is conducted on paver blocks with various proportions of fly ash & coconut fiber. Coconut fiber is used in different proportions such as 0.2%, 0.5%, 0.8% & 1% in the volume of concrete. Fly ash is used as replacement of cement in 10%, 15%, 20%, 25% by total weight of cement and gypsum is added in 1-2% by total weight of cement. After addition of coconut fiber the compressive strength of paver block changes considerably at 7 days, 14 days & 28 Days and maximum compressive strength is found when there is addition of 20% replacement of cement with fly ash and 0.8% replacement of sand with coconut fiber. For production of paver blocks 250-300 kg/m3 of cement is required. Conventional paver block cost 15-25 rupees in Indian market but pervious concrete paver block costs 10-20 rupees which indicates the from cost point of view also pervious concrete block is economical.
