Green concrete is a revolutionary subject matter in the records of concrete industry. Concrete is an environmental friendly material and the general effect at the environment according to ton of concrete is restrained. It affords the feasibility of using by way of product substances like 55 and 10% coconut shell and scrap tyres as a replacement of coarse aggregate in concrete. Aggregate give volume requiring little to no effort, containing 66 percent to 78 percent of the solid. With expanding worry over the inordinate misuse of normal and quality totals, the total created from modern squanders and agribusiness squanders being practical new hotspot for building material. This investigation was completed to decide the potential outcomes of utilizing coconut shell and scrap tyres as total in concrete. Using coconut shell and scrap tyres as total in solid creation not just takes care of the issue of arranging this strong waste yet in addition helps save common assets. In this paper, the physical properties of squashed coconut shell and scrap tyres total were displayed. The crisp solid properties, for example, thickness and droop and 28-day compressive quality of lightweight cement made with coconut shell as coarse total likewise displayed. The normal crisp solid thickness and 28-day 3D shape compressive quality of the solid utilizing coconut shell and scrap tyres total were 51.56 kg/m3 and 49.78 N/mm2 for 5% and 10% respectively. It is reasoned that squashed coconut shells and scrap tyres are appropriate when it is utilized an alternative for traditional aggregates in concrete. To avoid the pollutants and waste, the prevailing observe is performed. Thus, green concrete is an super substituent of cement as it is cheaper, because it uses waste merchandise, saving strength consumption inside the manufacturing. The concrete is made with concrete wastes which might be green so called as Green concrete. Over and exceptionally green concrete has greater power and durability than the ordinary concrete.
