Concrete is widely used as construction material around the world and it's properties have been undergoing changes through technological advancement. Generally, concrete having four constituents materials namely cement, sand, coarse aggregate and water. Advancement in technology enhance human comforts and at the same time it causes damages to environment. Waste plastic bottles are major cause of solid waste disposal and also disposal of metal caps of soft drinks bottles are headache to environmental engineers and involve either to recycle or reuse. Here we are going to add metal caps and PET bottles in concrete to increase the strength. This project represents the results to study the behavior of concrete by adding of bottles caps and PET with dosage of 0.5% of weight of cement as fiber to reduce the cement content to achieve IS10262:2009 and IS456:2000 requirements. PET bottles and metal bottle caps are added to the concrete at 0%,0.5%,1.0% and 1.5% by volume of total mixture and also analysis of the compressive strength, split tensile strength, flexural strength and them mechanical properties are compared with the conventional concrete. Grade of concrete used in the project is M20. Mix ratio is 1:1.5:3.
In spite of having low Compressive and flexural strength, No-fines concrete has properties capable of being used as rigid pavement for low traffic volume roads. Along with the mix proportions and water content to have sufficient bond between the aggregate particles, it is critical to determine what happens to the water once it penetrates the pavement surface. Different combinations of Cement, GGBS, water and Course aggregate with different maximum size and gradation were adopted for trial mixes to arrive at M20 grade concrete.M20 grade concrete is achieved with a w/c ratio of 0.36, Coarse aggregate of nominal size 20 mm passed and 10 mm retained ,cement is partly replaced with 30% of GGBS and with a cement to Course aggregate ratio of 1:4. Its compressive strength were observed to be 20.4 kN/m3.A perforated pipe can be provided at center of the pavement above sub-base such that it collects the water stored in concrete and drains it to the required treatment plant or a recharge pit.
The smart city consists not only the suffocated facilities but also it should consist of a smart solid waste management system. The huge generation of solid waste and shortage of land for dumping results in search of best schemes. Collection, transportation, and disposal of solid waste is a huge concern and also a very challenging task. Proper tools like IoT should be employed to integrate these works smoothly and efficiently. IoT consists of sensors which help in indicating the waste levels and collection routes to the server, from which the waste was collected in a quick and efficient manner. IoT contributes in all stages of waste management, which results in saving of time and money.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
