Optimization and prediction of fresh eco-efficient ultra-high-performance concrete properties

Description

The objective of this study is to investigate the most significant factors that may influence the rheological characteristics of UHPC. In this study, an attempt was made to Optimize UHPC mixtures containing various proportions of water, cement, and sand, with the Ns powder as a possible property enhancer. The aim of such Optimization is to determine the optimum ingredient proportions and Ns content to achieve the best rheological properties, such as flow, setting time, and HRWR requirements. The Optimization should also target the highest compressive strength as a strong indication of the overall mechanical behaviour.
