Abstract

The paper deals with partial replacement of coarse aggregate with granite stones. The effect of Shahabad stone (a variety of cuddapah) and the chemical admixture (superflo) on concrete was investigated. Natural aggregate had been replaced with the waste shahabad stone in four different percentages, i.e., 20, 30, 40 and 50. A comparison was made between the specimens of partially replaced coarse and the same set of specimens admixed with superflo. The effects on durability properties were reported.


Description

Following the increase in developmental activities world over, the demand for construction materials is increasing exponentially. This trend will have certainly greater impact on the economic system of any country. India is also aiming at a high developmental rate compared to other nations in Asia. There is heavy demand for building materials in the domestic market, which is becoming scarce day-by-day. At this point, researchers and engineers who have the foresight to keep the developmental activities abreast and curtail the cost factor should look out for other alternative building materials. The high consumption of raw materials by the construction sector results in chronic shortage of building materials and the associated environmental damage. In the last decade, construction industry has conducted various researches on the utilization of waste products in concrete in order to reduce the utilization of natural resources.
