Experimental Study on Hybrid Fiber Self Compacting Concrete
S. Saranya | M. Abinaya
Abstract: Self Compacting Concrete is a recently developed conception in which the ingredients of the concrete mix are proportioned in such a way that it can flow under its own weight to completely fills up the formwork and passes through the crammed reinforcement with no segregation and self consolidate without any mechanical vibration. Several studies in the past have exposed the expediency of fibers to develop the structural properties of concrete like ductility, post crack resistance, energy absorption capacity etc. Fiber reinforced self compacting concreting combines the benefits of self compacting concrete in fresh state and shows an enhanced performance in the hardened state due to the addition of fibers. In this project, glass fibers and polyester fibers were added to SCC and HFRSCC was developed. An attempt has been made to study mechanical properties of self compacting concrete and glass fiber reinforced self compacting concrete with addition of mild steel reinforcement. A strength based mix proportion of self compacting concrete was arrived based on Nan-Su method of mix design and the proportion was fine tuned by using Okamura's guidelines. Self compacting concrete mixes with partial replacement of cement by mineral admixture like fly ash were taken for investigation with and without incorporating glass fibers and polyester fibers.
