High Performance concrete (HPC) has received increased attention in the development of infrastructure Viz., Buildings, Industrial Structures, Hydraulic Structures, Bridges and Highways etc. leading to utilization of large quantity of concrete. This paper presents a comprehensive coverage of High Performance concrete developments in civil engineering field. It highlights the High Performance concrete features and requirements over conventional concrete. Furthermore, recent trends with regard to High Performance Concrete development in this area are explored. This paper also includes effect of Mineral and Chemical Admixtures used to improve performance of concrete.

The present study is carried out for evaluating the effect of aggressive environments like sulphate and chloride exposure on normal strength concrete. This paper presents results of experiments like the compression test (150mm×150mm×150mm size cubes), rebound hammer test and ultrasonic pulse velocity test (150mm×150mm×150mm size cubes), split tensile test (100mm diameter×200mm height cylinders), rapid chloride penetration test (100mm diameter, 50mm thickness specimen), sulphate and chloride attack test (150mm×150mm×150mm size cubes) performed on M30 grade concrete. The results clearly indicated that normal strength concrete cannot contribute significantly against sulphate and chloride attack.
