Abstract


Background/Objectives: The study investigates that alccofine and GGBS combination can be used in the SCC as the strength enhancer. SCC being a high performance concrete after the addition of alccofine, produces a high performance and high strength concrete. Methods/Statistical Analysis: Mix design for SCC can be carried out by Nan-Su method which is considered as a simple mix design and the dosage of super plasticizer will be determined by trial and error as substantial result of characteristics of fresh and hardened concrete and effect of alccofine (5%, 10%, 15% and 20% by volume) by keeping the GGBS percentage constant (30%) on rheological properties and strength properties were investigated. Findings Applications/Improvements: The improvement in behaviour of SCC is because of enhancement in union strength and pore refinement by GGBS. The outcome implies that the workability of SCC with 5% and 10% alccofine by volume of concrete leads to decline of other rheological properties given by codal provisions (EFNARC). In contrast, the improvement in properties of concrete like compressive strength from 36.6 to 42.9 N/mm2, splitting tensile strength from 3.8 to 7.9 N/mm2 and flexural strength from 4.9 to 8.3 N/mm2 at 28 days was observed with increase in alccofine dosage. Finally the conclusion has been drawn that alccofine and GGBS combination can be used in the SCC as the strength enhancer.
