Experimental Investigations on Strength Characteristics of High Performance Concrete Using Silica Fume and Superplasticizer

For several decades, concrete has been the most widely used construction material. Though conventional concrete CC performs very well under normal conditions, in special situations a very high compressive strength of concrete is necessary together with sustainability to aggressive environments. Hence, higher compressive strength of range 60-140 MPa is essential. The concrete mixes so far were designed only for strength and workability requirements. For the performance of long satisfactory life, the designed mixes should be checked and proved for their durability properties such as low permeability, high corrosion resistance, freezing and thawing resistance, fire existence etc. This necessitates a detailed study on High performance concrete HPC . This paper formulates a simplified mix design procedure for HPC by combining BIS and ACI code methods of mix design and available literatures on HPC. Based on the above procedure M80 and M100 mixes are arrived at. These HPC mixes are tested experimentally for compression, split tension, flexure and workability. The performance of the designed mixes is very good and the results are reported in this paper. Dr. K. Perumal | S. Senthilkumar | K.
