EXPERIMENTAL STUDY ON HIGH STRENGTH CONCRETE FOR DURABILITY USING METAKAOLIN, COPPER SLAG AND SILICA FUME

Advanced Concrete Technology

The aim of present investigation is to evaluate the Durability of High Strength Concrete (HSC) containing Metakaolin (MK) as a partially replacement of cement, Copper Slag (CS) as a partially replacement of fine aggregate and Silica Fume (SF) as a mineral admixture. The experimental study will be divided into three Series, namely Series-1 MK-10%, CS-10% based mixers with Coarse Aggregate 60%, Series-2 MK-15%, CS-15% based mixers with Coarse Aggregate 50%, Series-3 MK-20%, CS-20% based mixers with Coarse Aggregate 40%. The Fine aggregate is 10% for all three Series and water binder ratio is 0.40,0.45,0.48 for all three Series. The Mix design for M60, M65 and M70 is done for these three Series. The changes in durability will investigate by the absorption and Volume of Permeable Voids, Sorptivity Test, Initial Surface Absorption Test (ISAT). Performs results shows that Metakaolin as a partially replacement of cement to enhance the durability performance, silica fume are the most abundantly used pozzolanic materials because of its potential to consume portlandite during the process of hydration for improves durability, copper slag the strength and durability of partial replaced concrete.to evaluate the strength and durability the various test were conducted. these resulted that the concrete strength is increased with addition of copper slag with concrete. focused on the durability aspects such as sorptivity, sulphate attack and advanced techniques such as rapid chloride ion penetration test to assess the chloride ion penetration into the concrete.
