Abstract - Conservation of natural resources and preservation of environment is the necessary for sustainable development. Depletion of natural resources is a common phenomenon in developing countries like India due to rapid urbanization and industrialization, involving the infrastructure developments. India being second largest populated country in the world it has become very difficult to prepare a concrete by using natural resources to construct various structures such as Roads, buildings, bridges etc. Availability of natural sand in that is getting depleted and also it is becoming costly. To prevent exhaustion of natural resources such as natural stone, natural sand etc. an attempt is made to replace the natural materials by using waste crushed material along with Alccofine powder and Ground granulated blast furnace slag (GGBS).By using the waste and chemical compound with different proportions along with cement and with proper water cement ratio the suitability and performance of the above said materials is measured in this project.
environment, also the cost of the Natural sand is increasing day by day due to its scarcity. To overcome these problems, use of waste materials like Ground Granulated Blast Furnace Slag (GGBS), crushed sand and Alccofine can be used in Concrete. 1.1 Alccofine Alccofine 1203 which is supplementary cementious material is used in production of high performance concrete. It has low calcium silicate. Alccofine 1200 has different series like 1201, 1202, and 1203 which represents fine, micro fine and ultra fine particles. The percentage of water for the given workability in concrete can be reduced even up to 70% by use of Alccofine 1203.It can also be used as water reducer to increase the compressive strength and also the workability of concrete.
Key Words: Alccofine, Ground granulated blast furnace slag, Crushed Sand, Compressive strength. 1. INTRODUCTION The construction industry is the second largest industry in India after agriculture. It provides employment to large number of people and makes significant contributions to the national economy. For the construction of any structure the more important material required is concrete. Concrete is the second most used material in the world after water. The main ingredients required for preparation of concrete are cement, sand, aggregate and water. Pollution and Global Warming are the two most important problems the world is facing today. The excess use of natural resources such as Natural sand, aggregates and cement for the construction of any structure is affecting the Environment. In 2018 India was the second largest country for the production of cement in the world. The consumption of cement was around 270 Million metric tons per annum. India has emitted about 2,299 million tons of carbon dioxide in 2018 with increase of 4.8% compared to last year. The manufacture of cement contributes to 7% of global CO2 emissions. The raw materials used for production of cement are Lime stone and Clay, these materials are extracted from quarries, which also results in environmental degradation In the last few years it has been observed that availability of good natural sand for the construction is decreasing, excess use of natural sand is leading to environmental degradation which affects the Š 2021, IRJET
