Abstract: Concrete might be the maximum substantially used construction material in the global with approximately six billion tones being produced each year. It is best subsequent to water in phrases of in keeping with-capita consumption. However, environmental sustainability is at stake both in terms of damage due to the extraction of raw material and CO2 emission all through cement manufacture. This brought pressures on researchers for the discount of cement intake by means of partial substitute of cement by using supplementary materials. These materials may be obviously happening, industrial wastes or by way of-products that are less energy extensive. Fly ash and Ground Granulated Burnt Slag (GGBS) are selected specifically based totally on the standards of fee and their long lasting qualities., Not best this, Environmental pollution also can be decreased to a point due to the fact the emission of dangerous gases like carbon monoxide & carbon dioxide are very restricted. These substances (referred to as pozzalonas) when combined with calcium hydroxide, reveals cementitious compositions. Most commonly used pozzalonas are fly ash, silica fume, met kaolin, ground granulated blast furnace slag (GGBS). This wishes to look at the admixtures performance whilst combined with concrete so as to ensure a discounted existence cycle fee. The present research consists of three phases and reports the specializes in investigating characteristics of M35grade concrete .In the 1st phase the behavior of standard and SCM concrete (7.5%FA and 7.5%GGBS) of M35 grade specimens with different percentages of chemical admixtures curing with acids such as HCL. 2nd phase the same grade of specimens curing with Alkaline such as NaOH and in the 3rd phase the same grade of specimens curing with sulphate solution MgSO4 and finally assess the losses of mechanical properties and durability considerations of the concrete due to these conditions were reported.
