Comparative Study of High Performance Concrete by Replacing Silica Fumes and Addition of Recron 3S Fiber Material

Appari Sunil, Jain Sk, Saheb
The project deals with the high performance of concrete by replacing and addition of chemical admixtures for obtaining the characteristic target mean strength by replacing the silica fumes in cement and addition of polyester fiber material for getting maximum compressive strength, Split tensile strength, Flexural strength. High Performance Concrete (HPC) now a day's used widely in the construction industry worldwide. To produce HPC with normal ingredients we use mineral admixtures like Silica

The usage of mineral admixtures in the concrete not only enhances its strength properties But also durability. The compressive strength, split tensile strength, flexural strength are investigating finding the optimum use of mineral admixture (Silica fume of levels 0, 5, 10, 15 and 20% at 7 days and 28 days of curing). The present investigation aims to give design mix for HPC by using silica fume and super plasticizers. INTRODUCTION In construction industry, strength is a primary criterion in selecting a concrete for a particular application. The concrete used for gaining strength over a long period of time after casting. The characteristic strength of concrete is defined as the compressive strength of a sample that has been aged for 28 days.
