Mechanical and Durability Studies of Ultra-High Performance Concrete

Abstract

In the early 1990s, the building industry began using ultra high performance concrete for bridges and high rise structures.Yet, a developing nation like India has not yet fully embraced UHPC in its diverse infrastructure, despite its enormous unrealized potential. The most obvious reasons it isn’t employed in India are the expense and the absence of standards and expertise. There is a growing need for such concrete since it is becoming more and more important for the building to last long. Two mix design of UHPC from the literature were carried out with different admixture. From the results of these trial and error mixes, better one was chosen to cast to the similar. Trial mixture design of UHPC were subjected to water curing method only and its mechanical and durability properties are evaluated by compressive strength, flexural strength test,modulus of elasticity and work-ability of mix design by flow table test. Compressive strength of 80 MPa at 7 days and 120 MPa at 28 days for final mix design.
