STRENGTH & DURABILITY OF HIGH STRENGTH FIBRE REINFORCED SELF COMPACTING CONCRETE M. IYAPPAN

INTRODUCTION �Nano science and technology is a new field of emergence in materials science and engineering, which forms the basis for evolution of novel technological materials. Nano technology finds application in various fields of science and technology

�The Self Compacting Concrete (SCC) is the new category of High Performance Concrete (HPC) characterized by its ability to spread and self consolidate in the form work exhibiting any significant separation of constituents.

�This paper presents the benefits of SCC with Nano material and steel fibre, nano materials and steel fibres are used as partial replacement of Portland cement in Self compacting concrete with different percentage, then fresh and harden properties of SCC are

OBJECTIVES �To study the Effect of nano silica in the properties of self compacting concrete (SCC). �To study the fresh properties of SCC with nano silica (i. e Slump flow test, V-funnel test, L-Box test, U-Box test) �To study harden properties (Compressive strength, Split- tensile strength, Flexural strength) of SCC with partial replacement of cement by nano materials in three different percentage such as 0%, 2%, 4%, 6% and

�After evaluating the mechanical properties for the various mix and it is compared with conventional SCC concrete �To study the durability of SCC (the best results mix in harden concrete strength is chosen) using Rapid chloride test, Acid Resistance test. �For Application purpose, beam-column joint is chosen for my research work.

METHODOLOGY INTRODUCTION LITERATURE REVIEW PROPERTIES OF MATERIAL MIX DESIGN TEST ON FRESH CONCRETE CASTING & CURING TEST ON HARDEN CONCRETE (strength and durability test) APPLICATION PURPOSE (Beam column joint) RESULT & CONCLUSION

SIGNIFICANCE �Ability to completely fill complex formwork and encapsulate areas of congested steel reinforcement without any compaction and yet with reduced risks of voids and honeycombing. �Ability to develop higher early and ultimate strengths and enhanced durability properties compared with conventional vibrated concretes. �Improved constructability. �Labor reduction.

�Improved structural Integrity. �Accelerates project schedule. �Reduces skilled labor. �Flows into complex forms. �Minimizes voids on highly reinforced areas. �Allows for easier pumping procedure
