Nano-Modified Self-Compacting Concrete: Performance Evaluation Of Zinc Oxide And Magnetite Nanoparticles On Mechanical Strength Parameters

Abstract

In India’s ready-mix concrete sector, Self-Compacting Concrete (SCC) has become increasingly popular and is now extensively used in major construction projects. This study aims to conduct a comparative analysis of the hardened properties of M30 grade SCC by evaluating the influence of nanomaterials.^[1],[3] This research is centred on the use of Nano Zinc Oxide (ZnO) and Nano Ferric Oxide (Fe₃O₄) as performance-enhancing additives. The experimental program involves assessing the mechanical properties of SCC mixtures with and without nanomaterials, as well as mixtures incorporating varying proportions of these nanomaterials (0%, 0.5%, 1.0%, 1.5%, 2.0%, 2.5% and 3.0% by weight of the total powder content). The findings reveal a noticeable improvement in compressive strength at both 14 and 28 days with increasing dosages of nanomaterials. This study undertakes a comprehensive assessment of the mechanical performance of SCC, highlighting the potential benefits of Nano ZnO and Nano Fe₃O₄ in enhancing strength characteristics and contributing to the development of high-performance concrete.
