Development of High Strength Concrete Using Fly Ash and Alccofine

Mechanical properties of concrete is depend up on properties of ingredients and their relative proportion. since last few years the use of high strength concrete is globally used for the construction of strong and durable structure, to produced high strength concrete various supplementary cementitious material require to be used as mineral admixture. By considering the code, the present work deals with the development of fly ash, alccofine based concrete mix proportion to achieve high strength concrete. This paper presents the results of an investigation dealing with Concrete cubes of 150 mm size, to replace 10% and 17 % , cement with fly ash and Alccofine respectively. To acquire a different range of compressive strength of concrete various water cement ratio (W/C) of 0.2, 0.25, 0.3 and 0.35 were used for water content of 174 kg/m3 and 183 kg/m3 for a slump in the range of 1 to 2 inch and 2 to 3 inch. The effect of various parameters such as percentage replacement of mineral admixture, water to cement ratio and corresponding compressive strength is studied on fresh and hardened state of concrete. the objective of this study mainly consisted ofdeveloping relation between these parameters in the form of Graphs to specify proportioning of required fly ash, Alccofine based concrete.
