This project studies the recent investigations and development of combined application of Pozzolanic additions - Nano-Silica (NS) and Rice-Husk Ash (RHS) on the strength properties of concrete for sub sequential growth of concrete industry. This investigation not only saves the natural resources but also controls the environmental pollution by usage of wastes. The limited work is done on partial replacement of Rice-Husk Ash and Nano-Silica in cement paste, mortar and concrete. In the present study the cement is partially substituted by 20% and 30% of Rice-Husk Ash and Nano- Silica 2.0%, 4.0% and 6.0% by weight. To understand the application of Rice-Husk Ash and Nano- Silica various literatures have been reviewed and their influence on Compressive Strength, Bending Strength (Flexural Strength), Elastic Modulus or Young’s Modulus and Tensile Strength of M35 grade of concrete is investigated. The experimental investigation results of concrete are tabulated using the combination of various proportions of Rice-Husk Ash and Nano-Silica are collate with that of Controlled Concrete. The mechanical strength development and durability properties of concrete are greatly influenced because of this combined application of Nano-Silica and Rice-Husk Ash compared to the Controlled Concrete properties. The sustainable increase in the various strength characteristics of concrete prepared using Nano-Silica and Rice-Husk Ash can be accredited to the efficacious packing of colloidal particles and the need of additional binder in the application of Rice-Husk Ash and Nano- Silica.
