| Popis: | The paper presents durability properties of GlassFibre Reinforced Self Compacting Concrete (GFRSCC) ofdifferent grades. The durability of Glass Fibre Reinforced SelfCompacting Concrete (GFRSCC) using anti-crack highlydispersible glass fibres is reported in terms of acid resistance,surface absorption and sorptivity. The mixes were designedusing rational mix design procedure for SCC satisfying theEFNARC (2005) guidelines. In the first phase the mechanicalproperties of different grades are studied. In the second phasedurability properties like Acid attack factors, Acid-Durabilityfactors, sorptivity are studied for the Plain SCC(SCCP) andGlass Fibre Reinforced SCC(GFRSCC) and a comparison ismade. Based on the studies it is observed that the compressivestrengths of the GFRSCC were found to be about 10% morecompared to SCCP. With the increase in the grade of concrete,the sorptivity of GFRSCC is found to be reducing. With theincrease in duration of exposure to the acidic environment theASLF increased. SCCP and GFRSCC have shown more or lesssimilar percentage loss in strength for the same grade ofconcrete. With increase in period of immersion of the concretein various solutions (acids and sulphates), there was aconsiderable damage of concrete near the corners of thestandard cube and such disruption in GFRSCC was less than inSCCP. Overall, the GFRSCC was found to be more durableagainst both acids and sulphates. |
