Performance Evaluation of High-strength Concrete Incorporating Alccofine and Nanosilica
J. Environ. Nanotechnol., Volume 14, No 2 (June 2025) pp. 415-426
Abstract
Urbanization and infrastructure development necessitate the use of high-performance concrete due to its superior strength and durability. Traditional high-strength concrete often relies on increased cement content, contributing to environmental concerns due to carbon emissions. This study explores the use of supplementary cementitious materials (SCMs), specifically alccofine and nanosilica, to enhance concrete performance while reducing cement consumption. The research investigates M40 and M50 grade concrete with varying water-cement ratios (0.4, and 0.36). Concrete mixes incorporating alccofine and nanosilica were compared with control mixes to determine their optimal proportions. The study evaluates workability, mechanical properties (compressive, split tensile, and flexural strength), and durability aspects such as chemical resistance, water permeability, porosity, and sorptivity. Additionally, microstructural analysis was conducted. Results indicate that the inclusion of alccofine and nanosilica improves hydration, reduces porosity, and enhances mechanical and durability properties. The study underscores the potential of SCMs in developing sustainable high-strength concrete with reduced environmental impact.
