Concrete is world’s most used material after water for urban development. Concrete is made up of naturally occurring material such as Cement, Aggregate and Water. The cement is major ingredient of concrete and due to rapid production of cement, various environmental problems are occurred i.e.  Emission of green house gases such as CO2. The production of Portland cement is energy intensive.

Global warming gas is released when the raw material of cement, limestone and clay is crushed and heated in a furnace at high temperature of about 1500’C. Each year approximately 1.89 billion tons of cement has been produced world wide.

Every one ton of cement produced lead to about 0.9 tons of CO 2 emission and a typical cubic yard of concrete contains about 10% by weight of cement. There have been a number of article/ papers written about reducing the CO2 emission from concrete. Preliminary through the use of lower amount of cement and higher amount of supplementary cementanius material such as GGBS.

The researchers are currently found on use of waste material having cementations properties which can be added in cement concrete as a partial replacement of cement without compromising its strength and durability which result in decreases in cement production thus reduction in emission in green house gases i.e.CO2.The main purpose of this research  will solve using minimum quantity of cement and replace balance quantity with other cementanious material. In addition to that the byproduct of industries will be utilized which is harmful to environmental also and management of waste will be easily achieved.

The ground granulated blast furnace slag is a waste product from iron manufacturing industry which may be used as partial replacement of cement in concrete due to its inherent cementanious properties. This paper presents experimental study of compressive and flexural strength of concrete prepared with ordinary Portland cement and PPC partial replaced by GGBS in different proportions varying from 0 % to 100 %. It is observed from investigation that the strength of concrete is inversely proportional to the   40% of replacement of cement with GGBS.

In this research effect of partial replacement of cement with GGBS on strength development of concrete and cured under summer and winter curing environments is established. Three levels of cement substitution i.e., 0% to 100% have been selected. Early-age strength of GGBS concrete is lower than the normal PC concrete which limits its use in the fast-track construction and post-tensioned beams which are subjected to high early loads. The strength gain under winter curing condition was observed as slower. By keeping the water cement ratio low as 0.35, concrete containing GGBS up to 100% can achieve high early-age strength. GGBS concrete gains more strength than the PC concrete after the age of 28 day till 90 day. The mechanical properties of blended concrete for various levels of cement replacement have been observed as higher than control concrete mix having no GGBS.

Cement is major constituent material of the concrete which produced by natural raw material like lime and silica. Once situation may occurs there will be no lime on earth for production of cement. This situation leads to think all people working in construction industry to do research work on cement replacing material and use of it. Industrial wastes like Ground Granulated Blast Furnace Slag (GGBS) show chemical properties similar to cement. Use of GGBS as cement replacement will simultaneously reduces cost of concrete and help to reduce rate of cement consumption. This study report of strength analysis of GGBS concrete will give assurance to encourage people working in the construction industry for the beneficial use of it.
