Design of High Strength Concrete Using Superplastisizer and Stone Dust

Concrete is the most widely used construction material today. Increase in construction activities have led to an increase in demand for the various raw materials in concrete, especially river sand which is the conventionally used fine aggregate. Due to increase in mining process, the availability of this river sand is becoming scarce. This led to researches on alternate materials as ingredients of concrete that are in no way inferior to the conventional materials. Manufactured sand was one of the alternate materials proposed. Though manufactured sand has many advantages, one of the major areas of concern is the fine material of size 150 micron and down removed during the manufacturing process and accumulated as a waste material. The paper presents the laboratory investigations and a comparative study on the mechanical properties and behaviour of high strength concrete an mortar using fine stone dust, the residue produced during the production of manufactured sand.
