Abstract:

 This paper presents the development of Ultra- High Performance Concrete (UHPC)using economical materials. UHPC mixture proportions were developed using local materials such as silica fumeso that UHPC may be made more affordable to a wider variety of applications. The Ultra-High Performance Concrete (UHPC) tested in this research is steel fiber reinforced concrete consisting of an optimized gradation of fine powders and a very low water/cement ratio. Experimental investigation was carried out for two different UHPC mixes(Mix1 and Mix2) with different water cement ratio of 0.26 and 0.3 respectively. Both the UHPCmix had different values of steel fibre in terms of volume fraction (1%, 1.5% and 2%). At the end of 28 days it was found that the UHPC Mix1 with water cement ratio of 0.26 showed 31.5% increase in compressive strength for 2% of steel fibre content. Also the UHPC Mix1 showed a higher split tensile strength of about 6.36Mpa.

Keywords:
