HIGH STRENGTH CONCRETE USING PURIFIED FLY ASH
For the shelter requirements of widely spreading population civil industry also spreading enormously. With different and advanced construction techniques numbers of materials used in this construction procedure are also developed and used in general practice. Cement is base product for every type of construction. It is made from natural material with special factory procedure. This cement or cementitious material has strength up to 53 MPa. But while practicing higher grade concretes which has strength more than 65 MPa we have to use some special processed material mixture with cement. During this material study we have to use material purified fly ash. This fly ash possess some good qualities like extra silica percentage, more fine and better surface area. So it is better option than factory waste fly ash and silica fume to achieve desired strength of concrete. With different trial mixes we can use it in general practice.
