In the recent past, there has been a remarkable growth in usage of admixtures in concrete for improving the properties of concrete with respect to strength and durability, especially in aggressive environments. High performance concrete (HPC) appears to be better choice for a strong and durable structure. Suitable addition of mineral admixtures such as silica fume (SF), ground granulated blast furnace slag and fly ash in concrete improves the strength and durability characteristics of concrete.
This paper presents the results of an experimental investigation carried out in the laboratory on the performance of M110 grade of HPC trial mixes having different replacement levels of cement with SF. The strength and durability characteristics of these mixes are compared with the mixes without SF. Compressive strength of 110MPa at 28 days is obtained by using 10 percent replacement of cement with SF. The results also show that the SF concretes possess superior durability properties.
