The Concrete Mix: Mixing UHPC: Ultra High Performance Concrete
Mixing UHPC: Ultra High Performance Concrete I was introduced to UHPC or Ductal as it is often called nearly ten years ago when visiting a concrete pipe plant in Quebec. They had been running tests with it and when they showed it to me what I saw was a very thin sheet of very dark concrete.
Development of high-performance heavy density concrete using
After extensive trials and errors 15 concrete mixes were prepared by using the coarse aggregates of barite magnetite goethite and serpentine along with addition of 10% silica fume SF 20% fly ash FA and 30% ground granulated blast-furnace slag GGBFS to the total content of OPC for each mix. To achieve the high-performance concrete HPC
High Performance Concrete Topic
High-performance concrete HPC is concrete that has been designed to be more durable and if necessary stronger than conventional concrete. HPC mixtures are composed of essentially the same materials as conventional concrete mixtures but the proportions are designed or engineered to provide the strength and durability needed for the structural and environmental requirements of the project.

The Importance of Concrete Mix Design Concrete Supply Co.
It is the more used mix of the two. Normal performance concrete has good workability if all of the mix ingredients are in accurate proportions. When freshly mixed the concrete must be plastic or semi-fluid so that it can be molded. High-Performance Concrete . A high-performance concrete mix has a performance strength above 40 MPa.

High Performance Concrete - an overview ScienceDirect Topics
Besides the production of high-performance concrete superplasticizers are also commonly used in the production of high-workability concrete. With a slump value of 180–230 mm high-workability concrete can be pumped rapidly over long distances easily compacted in structures with highly congested reinforcement and can even be self-compacting
