Reinforced cement concrete is prevailing construction materials for building of varieties of infrastructuresworldwide. The demands on reinforced concrete aggregates (fine aggregate, coarse aggregate) are increasing day byday. Scrap tires are disposing and dumping in world in huge bulk. Accumulation of crumb rubber from tire scrap isdangerous and threatening to environment. As rubber is non-biodegradable and resistant to most natural environmentalconditions, hence its direct disposal into environment or even burning in kiln creates lot of problems and environmentalcontaminations. Therefore, alternatives are required to get counteracted with the excessive demands on theseingredients. Researchers investigated experimentally crumb rubber concrete at different structural member levels i.e.beam, column, cylinders etc. and found reduced mechanical strengths while some parameters were improved upontesting. In current study two frames (plane frame) in 1/3rdreduced scale models meeting simple similitude requirementswere constructed. One frame was of normal concrete and another one of crumb rubber concrete (incorporating 20%crumb rubber). The mix ratio used in superstructure for both models were 1:1.75:1.82 with water/cement ratio of 0.52and 1:1.60:3.40 with water/cement ratio of 0.49 for foundation pads construction. Total twelve standard concretecylinders were fabricated comprised three cylinders for each storey of normal concrete frame as well as of rubberizedaggregate concrete frame model. Crumb rubber powders were incorporated and replaced fine aggregate by volume with20%. The maximum size of coarse aggregate used in current study was 8mm.
