High Performance self compacting concrete, using Alcofine and flyash

The present day world is witnessing the construction of very challenging and difficult Civil Engineering structures. Quite often, concrete being the most important and widely used material is called upon to possess very high strength and sufficient workability properties. Efforts are being made in the field of concrete technology to develop such concrete with the required special characteristics such as high strength, suitable workability and improved durability. This project is meant to present the results of experimental investigation carried out to evaluate the effectiveness and performance of Self Compacting Concrete with OPC cement in addition of Alccofine 1203 and Fly Ash. In this project we have replaced OPC cement with varying percentages of Alccofine and fly ash to obtain high performance concrete having required properties.12 different mixes in which cement is replaced by fly ash from 24.5 up to 36 % and Alccofine varying in sequence 4 to 10 % have been prepared. The self compacting characteristics are obtained by the use of Poly-Carboxylate based Super plasticizer. All this batches have been tested for compression, flexure and split tensile strengths.
