Abstract

This paper describes about the investigation undertaken to examine the suitability of recycled concrete as a substitute for fine aggregate. Recycled concrete (artificial sand) is used for 40% of fine aggregate and natural sand is retained for the remaining part. HPC of M60 grade is attempted, with different replacement levels of cement with Fumed Silica. Maximum 28-day compressive strength of 68.26MPa with 1.0 percent replacement of Cement with Fumed Silica was observed for a water-binder ratio of 0.33. Acid resistance and Chloride impermeability increases with increase of Fumed Silica content. Tests on sorptivity, saturated water absorption, coefficient of water absorption and porosity were also conducted.

Keywords

High Performance Concrete, Fumed Silica, Recycled Aggregate, Durability, Micro Structure Property.
