So to reduce the emission, various types of concrete are developed using waste products from industries and agricultural use like blast furnace slag, silica fume, fly ash which requires low Amount of energy and also cause least harm to the environment. Green concrete is a new technology developed now days to reduce the effect on environment by production of cement. Cement contains high amount of carbon-di-oxide which harms the environment drastically, so by replacing the cement by various materials which causes harm to the environment we not only reduce the problem of disposal of these materials but we reduce the emission of carbon-dioxide from cement and as a result of which we reduces the negative effect on environment. Keywords - Green Concrete, Silica fume, Demolished Brick Aggregate, CO2 Emission, Eco-Friendly concrete. I. INTRODUCTION Color has nothing to do with green concrete. It is a concept of thinking and environment into an every aspect of the raw materials manufacture over construction, mixture design to structural design, and durability. Green concrete is very often considered to be cheap to produce due to the use of recycled material whereby avoiding the charges for the disposal of waste, less energy consumption and greater durability. While a normal construction practices are guided by short term economic considerations, sustainable construction is focused on best practices which emphasize on long term affordability, durability and effectiveness. At each stage of the life cycle of the construction, it increases ease and quality of life, while minimizing the negative environmental impacts and increasing economic sustainability of the construction. Any infrastructure designed and constructed in a sustainable way minimizes the use of resources through the whole life cycle of the construction process in which the green concrete play a vital role in achieving the sustainable construction. Having so much of advantageous has led to popularity in construction world and one of the emerging technology in sustainable construction. Green concrete is miracle of present and tool for future when the natural resources are on the verge of extinction. Š 2017, IRJET

Due to growing interest in sustainable development, engineers and architects are motivated more than ever before to choose materials that are more sustainable. Selection of material for concrete is more sustainable and minimizes environmental impact. Cement production accounts for more than 6% of all CO2 emission which is a major factor in the world’s global warming (Greenhouse gas). India is the third largest cement producer in the World and one of the largest consumers of cement per capita in the world. Rough figures are that India consumes about 1.2 Ton/year/capita, while as World average is 0.6 Ton/year/capita. CO2 emissions from 1 ton of concrete produced vary between 0.05 to 0.13 tons. 95% of all CO2 emissions from a cubic meter of concrete are from cement manufacturing. Cement is the one of the major component of the concrete. The production of one ton of cement releases one ton of a CO2 into the atmosphere. CO2 is known to be greenhouse gas that contributes to the global warming. The reduction in CO2 emission from a concrete can be achieved with a partial replacement of cement by the various supplementary cementitious materials. The use of these cementitious materials has resulted in an improvement of the properties of concrete. So to reduce this environmental impact green concrete plays a vital role. By using recycled materials or waste materials which are harmful to the environment as a replacement of cement such as fly ash, silica flume, etc. we can reduce the CO2 emission from concrete as well as it reduces the environmental impact on earth. As a result of which green concrete is one of the major tool in the future when the natural resources are on verge of extinction. II. OBJECTIVES 1) To study the effect of silica fume on the environment. 2) To study the effectiveness of concrete by partial replacement of cement by silica fume. 3) To determine the strength of new mix design concrete of grade M40. 4) To determine the various test results like compression test, flexural test & split tensile test. 5) To find the optimum percentage of silica fume in cement so that we can achieve maximum strength by increasing percentage as 5%,10%,15%,20%.
