Development of ultrahigh strength concrete and its performance on beam elements

Abstract

Ultra-High Strength Concrete (UHSC) is a relatively new generation newlinecementitious material that has a compressive strength of over 100 MPa and newlinebetter durability. It is a concrete of the future, with the potential to improve newlinethe sustainability of structures and other infrastructure elements. With the newlinehelp of locally accessible river sand that confirms zone II (IS 383 : 1970), newlinecoarse aggregate of 12 mm size, OPC (RAMCO) of 43 grade with Elkem newlinemicrosilica grade 920D, and MasterGlenium SKY 8233 (Polycarboxylic ether newlinebased) as superplasticizer, this experimental investigation aims to produce an newlineoptimal mix proportion of UHSC. This study restricts the use of multiple newlinechemical and mineral admixtures, different types of fibers, and special curing newlinemethods like accelerated curing. UHSC structural elements may be used to newlinereplace conventional components, it is essential to comprehend how they newlinebehave structurally, under different loading scenarios. Despite the fact that newlineseveral research projects have been carried out, the findings are dispersed, newlinemaking it difficult to assess the behavior of UHSC. newline
