| Abstract | It is generally agreed that Ultra-High Performance Concrete's (UHPC) exceptional mechanical characteristics, durability, and potential for eco-efficient building techniques justify its recognition. Recent years have seen a heightened emphasis placed on producing UHPC with fewer environmental implications, while retaining or improving its performance features, in response to the growing demand for eco-friendly construction materials. To find a happy medium between high mechanical performance and low environmental impact, this thesis investigates the formulation of Eco-Efficient Ultra-High Performance Concrete via the lens of a statistical mixture design technique. Cement, aggregates, and chemical admixtures all must work together in intricate ways for the UHPC to turn out the way it's supposed to. This research uses a statistical mixture design method that considers the combined and interactive effects of many different factors. The particle-packing technique informs the experimental design, and the response-surface methodology is used to the data gathered from the experiments. The primary goal of this research is to determine how to best construct a UHPC mix that simultaneously increases compressive strength, flexural strength, and concrete working efficiency. The experimental findings demonstrate the efficacy of the statistical mixture design method in optimizing the UHPC mix design. Optimal mix design shows a compressive strength of up to 120 MPa and a flexural strength of up to 14 MPa. The findings of this study have significant implications for the future of UHPC, which might lead to materials with enhanced qualities suitable for a wide variety of uses. This thesis was written with the intention of being used as a reference for academics, engineers, and politicians who are interested in promoting more environmentally friendly building methods. |
