Abstract: In mass concrete works, when normal water is used in preparing the concrete mix, it leads to high amount of heat of hydration and thermal cracking, but with the use of chilled water for the same, the amount of heat that is produced in the concrete can be dissipated and thereby reducing the thermal cracks. The concrete mix thus produced is called Temperature controlled concrete. The present work carried out results in Temperature Controlled Self Compacting High-Performance Concrete. This is achieved by studying the self-compacting properties at the fresh state of concrete along with the durability and strength properties of the concrete. Several tests were carried out by using various supplementary cementitious materials and super plasticizer to obtain self-compacting concrete with high performance. The mix thus prepared constitutes 22% of Fly ash and 5% of Alccofines by replacing binder content in the concrete. Comparative study on the compressive strengths of the mixes prepared with nominal concrete, concrete with fly ash and concrete with fly ash and alccofine together was done. From the tests, the results achieved show’s that, the mix prepared with the Alccofine gives more strength when compared with other mixes. This is due to the usage of supplementary cementitious material and their fineness properties along with water retarding super plasticizer. This will enhance the flow and durability properties of the concrete.
