Concrete is especially labeled into 3 sorts based totally at the density. Concrete containing herbal sand and gravel or beaten- rock aggregate and water, when positioned within the skeleton of form and allowed to treatment, becomes difficult like stone. Generally weighing approximately 2400kg/m3 is known as “regular-weight concrete” and it's far the most commonly used concrete for structural purposes. For packages wherein a higher strength-to-weight ratio is desired, it is viable to lessen the unit weight of concrete via the use of natural mixture with decrease bulk density. The time period light-weight concrete is used for concrete that weightless than 1800 kg/m3. Heavy weight concrete used for radiation shielding, is a concrete produced from high density aggregate and usually weigh more than 3200kg/m3. Our goal it is to study the residences of concrete by using in part changing cement by means of fly ash and fine aggregate (sand) by using Granulated Blast Furnace Slag (GBFS). On this look at, cement was partially replaced by way of fly ash and best mixtures were in part changed by means of GBFS in concrete. A combination layout became executed for M20 grade of concrete by using is technique. Three grades of Ordinary Portland Cement (OPC) particularly: 33, 43 and 53 as labeled by means of Bureau of Indian Standard (BIS) are commonly utilized in production industry. Now in this mission most effective 53 grade of cement is used. This paper reports comparative have a look at on consequences of concrete residences by using in part alternative of OPC of 53 grades with fly ash and sand had been partially changed by way of blast furnace slag. The principle variable investigated in the take a look at of version of fly ash dosage of 10% and slag dosage of 10%, 20%, 30% fly ash dosage of 20% and slag dosage of 10%, 20%, 30% fly ash dosage of 30% and slag dosage of 10%, 20% and 30%. The compressive power and split tensile strength & acid assault of concrete were specially studied. Test outcomes indicate that, inclusion of fly ash and GBFS commonly improves the concrete houses up-to positive percentage of substitute in 53 Grade of cement
