An experimental study on strength & flowability of self-compacting concrete
R. Ravi, Sumanth Doodala
Self-compacting concrete (SCC) is a development of conventional concrete, in which the use of vibrator for compaction is no more required. Self-compacting concrete was first developed in 1988 to achieve durable concrete structures. Since then, various investigations have been carried out and this type of concrete has been used in practical structures in Japan, mainly by large construction companies. Investigations for establishing a rational mix-design method and self-compactability testing methods have been carried out from the viewpoint of making self- compacting concrete a standard concrete.rnIn the present work two grades M20 SCC mix was developed using EAFNARC mix design concept to arrive at the proportions of aggregate. Compressive strength tests were conducted to know the strength properties of the mixes. A simple mix design procedure has been developed using EAFNARC mix design on SCC. Compressible packing model is used to arrive at the proportion of aggregates, cement content and fly ash content are obtained from previous studies and modified accordingly as per EAFNARC standards to achieve optimum mix proportions satisfying fresh properties, hardened properties and also economy.
