Exploitation of plastic bags in roadway blocks

Plastics are an increasingly important component of urban solid waste. The disposal of waste materials, such as used plastic bags, has become a major issue. The vast amount of waste plastic bags collected in the twenty-first century has posed significant challenges for their disposal. The amount of waste plastic in the home is substantial and growing. Our results indicate cement blocks are ideal for laying and finishing pathways and streets because they are easy to lay and finish. This study was carried out on experimenting the substitute materials in the mixture of cement blocks a component of building materials which is normally manufactured using the mixture of cement, fine aggregate and water, following a certain ratio. A series of three different percentages of plastics bags were added with the mix and certain quantities were replaced by quarry dust instead of Fine aggregate. Tests were done on the blocks to study its compressive strength, split tensile strength the water absorption percentage and acid test. Both the test compressive and split tensile tests were conducted on the seventh and 28th day. Based on the results acquired, for compressive strength tests on the 28th day, the result a good indication is that the blocks can be produced by replacing the cement and fine aggregate with utilizing the plastic for and effective way of 1:1 and 1:2, with 10& 20% replacing with quarry dust having strength 10.7 and 9.5 N/mm2 respectively Which is 165 more than the conventional type of blocks. Similarly the water percentage is also nil and very marginal in the same proportions. The decrease in weight is existed in all the samples tested the result is equal in all mix compositions. This is uniform rate implies block undergo certain abrasion. Conclusions were drawn for utilising the above composition in a suitable non structured places and minimizing the plastic waste.
