Fresh and Hardened Properties of Ternary Blended Fast Setting Early Strength Fibre Reinforced Self Compacting Concrete

Cement, used for engineering the concrete structures has become most demanded construction material, production of which consumes enormous quantity raw materials and thereby emits approximately 7% greenhouse gas emissions into environment. Determinations are being made to use, as much possible, supplementary cementitious (SCM), like ground granulated blast furnace slags (GGBFS), flyash (FA), metakaolin (MK), silica fume (SF), rice husk ash (RHA), etc., industrial by-products hold pozzolanic properties, capable be a part replacement ordinary portland cement (OPC). The consumption OPC significantly increased all over world due infrastructure facilities on massive scales. Also aged infrastructure, constructed decades before, necessities maintenance repairs further increase demand thus cause higher impact Researches trying experimentations in finding out suitable combinations various proportions potential finer SCMs viz. FA, GGBFS etc. ultrafine SF, MK, RHA investigated along with different types fibres produce fibre reinforced self-compacting use fast track constructions repair works. In this study ternary blended SCC FSCC (fibre SCC), mixes were established ranging from 64% 74%, MK (as SCM), OPC, varying 2.5%, 5%, 7.5% 10%; Fly fine SCM) fixed at 25%, without 1% Alkali resistant (AR) fibre. set target achieve maximum final setting time 10 hours, 1 day compressive strength 25 N/mm2 flexural 2.5 besides meeting characteristics slump flow 550mm-650 mm (SF1), V Funnel 9-25 Seconds (V2 class) facilities.
