---------------------------------------------------------------------***--------------------------------------------------------------------Abstract:-The purpose of this study is to investigate to more than 1t per 1t of cement production . Due to the effects of concrete on the environment .There is a this fact ordinary cement, which is often called as huge growth in Construction industry . Many new Portland cement, unfortunately is being serious technologies have evolved very rapidly to cater environment and atmospheric pollutant. This is different difficulties in the construction industry. happening because of fact that producing cement Concrete is one of the most important materials in a clinker involves very well-known reaction called construction industry, among all the material used for calcinations of calcium carbonate which can be construction purposes. The process of manufacturing written is this equation (1): of cement emits near about eight to ten parent of total world’s carbon dioxide . The global warming gas is 5CaCO3 + 2SiO2 → (3CaO,SiO2)(2CaO,SiO2) + 5CO2. released when limestone and clays are crushed and heated to high temperatures. In recent year , the Aggregates are the main constituent of concrete. The recycling of waste and industrial by products gaining availability of aggregates has emerged problems in popularity to make concrete environment friendly recent times due to continuously mining ., There is material and the concrete can be called as Green need to find replacement to some extent to cater this Concrete. Green concrete is defined as a concrete problem . Nowadays, there is a solution to some which uses waste material as at least one of its extent and the solution is known as “Green components, or its production process does not lead to Concrete..’’Green concrete has nothing to do with environmental destruction, or it has high-performance colour. It is a concept of thinking environment into and life cycle sustainability. This review paper will concrete considering every aspect from raw help to give us a brief idea about advantages and materials manufacture over mix design to structural disadvantages of green concrete. design, construction, and service life. The production cost of Green concrete is less i.e green concrete is cheap to produce because, waste products are used Key Words — Concrete, Green Concrete, Recycled Aggregates, Fly Ash, Recycled Aggregate Concrete, as partial substitute for cement, charges for the Cement, Fine Aggregate, Coarse Aggregate, Admixture. disposal are avoided, energy consumption in production is lower, and durability is greater. Waste 1.INTRODUCTION:can be used to produce new products or can be used as admixtures so that natural resources are used Environmental protection and conservation has more efficiently and the environment is protected become a major world issue in the global context.All from waste deposits. over the world the size of construction industry is growing at faster rate. The demand for construction IMPACT ON ENVIRONMENT DUE TO CONCRETE:materials increases very much, due to huge growth in a construction . When the raw material of cement, limestone and clay is crushed and heated in a furnace I. Cement production produces carbon dioxide at high temperature (±15000C),the global warming which is one of the greenhouse gases which is gas is released in large amount.Approximately 1.89 responsible for global warming. About0.9 billion tons of cement (which is one of the major tons of carbon dioxide is produced for every component of concrete) have beenproduced 1 ton of cement produced. worldwide ,each year . In traditional cement CO2 emission is very high and in some cases can be equal © 2017, IRJET
