Use of Recycled Plastic and Coconut Shells in Concrete to Improve Strength

Abstract: There is considerable imbalance in the conventional building materials; there is a great demand in recent past years. In quarries while cutting out the lateritic stone with help of cutting machines which produces 15-20% of soil wastes which poses a problem of disposal & utilizing the quarry waste. The quantity of plastic waste and waste from coconut in municipal solid waste collection is expanding rapidly ,the rate of expansion is double for every 10 years since plastic is non-biodegradable which remain on earth for 4500 years without degradation & it is a great challenge in disposing of waste plastics ,it is also danger in repeat recycling of plastic waste it poses a danger of being transformed to a carcinogenic materials & only a small amount of pet bottles are recycled, it has a many good characteristics such as versatility ,hardness, resist to chemical ,water impacts. In recent years, the natural sand is replaced by the m-sand, m-sand is also used in mixture of plastic & soil, in this work an attempt has been made to manufacture of blocks by using the waste plastic in range of 5-20% by weight of course aggregate. The blocks manufactured possess the properties such as neat & even-finishing with negligible water absorption & which satisfies the compressive strength to a certain extent. Tender coconut husk is biodegradable but it is hard husk. It takes a long time to degrade owing to its high moisture content and size. As the urban population takes to this healthy drink, especially during summers, the rising pile of leftover tender coconut husk is becoming a nuisance of sorts. The accumulation of husks in landfills or their burning release harmful pollutants, leading to soil and water pollution. Furthermore, the decomposition process contributes to greenhouse gas emissions, exacerbating climate change concerns.
