Study on the Stress-Strain Behaviour of High Strength Glass Fibre Reinforced Self-Compacting Concrete under Axial Compression with & without Confinement

A self-compacting concrete (SCC) is the one that can be placed in the form and can go through obstructions by its weight and without the need for vibration. Although there are visible signs of its gradual acceptance in the Middle East through its limited use in construction, it has yet to explore the feasibility and applicability of SCC in new construction. The contributing factors to this reluctance appear to be lack any supportive evidence obits suitability with local marginal aggregates and the harsh environmental conditions. Concrete is a vital ingredient in infrastructure development with its versatile and extensive applications. It is the most widely used construction material because of its mouldability into any required structural form and shape due to its fluid behavior at an early age. However, there is a limit to the fluid behavior of normal fresh concrete. Thorough compaction, using vibration, is normally essential for achieving the required strength and durability of concrete. Inadequate compaction of concrete results in a large number of voids, affecting performance and long-term durability of structures. Self-compacting concrete (SCC) provides a solution to these problems. As the use of Concrete becomes more widespread the specifications of concrete-like durability, quality, and compactness of concrete becomes more important. Self -Compacting Concrete is a recently developed concept in which the ingredients of the concrete mix are proportioned in such a way that it can flow under its weight to fill the formwork and passes through the congested reinforcement without segregation and self-consolidate without any mechanical vibration. Self–Compacting Concrete (SCC) is a very fluid concreter and a homogeneous mixture that solves most of the problems related to ordinary concrete. This specification helps the execution of construction components under high compression of reinforcement.
