An Overview of Some Development in CONCRETE TECHNOLOGY
High-volume fly ash concrete technology was developed at the Canada Centre for Mineral and Energy Technology (CANMET), Ottawa, Canada in 1980’s. It enables minimizing the amount of cement required to produce high quality concrete for different types of applications by incorporating upto 50 to 60 percent fly ash in the concrete mix.Learn More
