Civil Engineering: HIGH PERFORMANCE CONCRETE
High performance concrete is a concrete mixture, which possess high durability and high strength when compared to conventional concrete. This concrete contains one or more of cementious materials such as fly ash, Silica fume or ground granulated blast furnace slag and usually a super plasticizer.
Use of Mineral Admixtures in Concrete - 東京工業大学
Is developed by mixing two or more kinds of mineral admixtures with the aim of further improving the performance of blended cement. This cement helps provide higher fluidity, higher strength, higher density, higher durability, lower hear evolution, and increase resistance to alkali aggregate reaction of concrete and is mainly used for massive

Why is admixture used? Over decades, attempts have been made to obtain concrete with certain desired characteristics such as high compressive strength, high workability, and high performance and durability parameters to meet the requirement of complexity of modern structures.The properties commonly modified are the heat of hydration, accelerate or retard setting time, workability, water ...
Experimental Study on C60 High Performance …
The C60 high performance concrete was prepared by adding high content mineral additives and reducing water-binder ratio. This kind of concrete has good work performance and higher pumpability. It also has a low shrinkage and creep feature. Experiments were carried out to compare performance to concrete without mineral additives.
