Strength and Durability of High Strength Fibre Reinforced Self Compacting Concrete with Nano Silica

Conventional concrete used in building and civil engineering applications requires compaction to achieve strength, durability and homogeneity. The typical method of compaction, vibration, generates delays and additional costs in projects and moreover is a health hazard in and around construction sites. Self-Compacting Concrete is a highly flow able, stable concrete which flows readily into place, filling formwork without any consolidation and without undergoing any significant segregation. In the present experimental investigation the glass Fibres are added in different proportion (0%,0.5%,0.75%,1%) to total volume of cement and 4% of nano silica is constantly added in all mix of SCC & to study the fresh and harden properties such as workability, compressive, split tensile flexural strength and durability test (sulphate resistance) on M50 grades concrete. Finally the test results are compared with conventional concrete. Based on the tests results, the use of 0.75% glass fibre with 4% of nano silica in self compacting concrete improves the quality of concreting & produce comparatively better results in both strength as well as durability aspect.
