The growing need for long-lasting, environmentally friendly, and reasonably priced materials has drawn a lot of attention to the design and production of high-performance concrete (HPC) in the building sector. The goal of this study is to improve the qualities of concrete by adding Alccofine, a specific micro-fine substance, and micro-silica, also known as silica fume. Alccofine, which is renowned for its exceptional workability and strength enhancement, and micro-silica, a pozzolanic substance, are utilized as supplementary cementitious materials (SCMs) in concrete mixtures. When these ingredients are combined, the concrete's permeability and shrinkage are decreased and its mechanical qualities—such as its compressive strength, tensile strength, and durability—are improved. The microstructure is strengthened by the extra calcium silicate hydrate (C-S-H) gel that is created as a result of the pozzolanic reactions between the micro-silica and the calcium hydroxide in the concrete matrix. By improving the mix's workability and offering superior finishing qualities, alccofine helps to lessen bleeding and segregation. This concrete mix is perfect for use in infrastructure projects that need long-term durability because it also provides enhanced resistance to harsh environmental factors like chemical attack, freeze-thaw cycles, and high temperatures. The mix design, performance attributes, and possible uses of high-performance concrete utilizing micro-silica and Alccofine are described in this study, highlighting their contribution to the development of concrete technology toward more durable and sustainable building methods.
