Maintenance and repair of concrete structures is a growing problem involving significant expenditure. As a result carried out worldwide, it has been made possible to process material to satisfy more stringent performance requirements, especially long-term durability. The broad aim of this work was to investigate the effects of partially replaced Ordinary Portland Cement (OPC) by Ground Granulated Blast Furnace Slag (GGBS) on the durable properties of concrete. The cement was replaced with GGBS, Metakaolin. In addition to this Nano-Silica was used in concrete to enhance the durable properties of concrete. The concrete cubes was made with replacement of certain above ingredients cubes was made in both conventional and replacement with ingredients after 28 days normal curing cubes was sink in tank with solution of Hydrochloric acid, Sulphuric acid and Acitic acid with 5% solution made and take weight of cubes after 28 ...

The maximum compressive strength value was obtained by replacing GGBS (Ground Granulated Blast Furnace Slag) with cement and the maximum flexural strength value was obtained by replacing Metakaolin (MK) with cement. It was observed that maximum compressive strength value can be obtained by replacing 2% Colloidal nano-silica (CS) with cement however It was also observed that replacing Colloidal nano-silica (CS) with cement beyond 2% reduces the compressive strength value. Replacing cement by 3% to 5 % colloidal nano-silica (CS) will be more effective in the improvement of the mechanical properties of self compacted concrete than the replacement of 10% micro silica (MS) in a concrete.
