2012-5-30 · High Performance Concrete Admixtures Euclids special class of high range water reducers lower watercement ratios increasing slump to produce flowable concrete. Our high range water reducers offer high early strengths and the enhanced workability and pumpability needed in todays competitive concrete construction market.
Fly ash the mineral additive marketed as Condensil is vital for making durable high-performance concretes. The Vicat Group produces a wide range of artificial cements meeting every building requirement. The Group has annual cement production capacity of 30 million metric tons.
These mineral additives not only yield concrete with improved properties and economical effectiveness but they also improve the eco-balance of these materials39. As a result of these developments the concept of high-performance concrete HPC has been put forward and successfully applied worldwide.
High Performance Concrete Additives. Mineral admixtures affect the nature of the hardened concrete through hydraulic or pozzolanic activity. Pozzolans are cementitious materials and include natural pozzolans such as the volcanic ash used in Roman concrete fly ash and silica fume.

2019-6-14 · Ultra-high-performance concrete. Ultra-high-performance concrete is a new type of concrete that is being developed by agencies concerned with infrastructure protection. UHPC is characterized by being a steel fibre-reinforced cement composite material with compressive strengths in excess of 150 MPa up to and possibly exceeding 250 MPa.
Ultra-High Performance Concrete UHPC is a relatively new construction material which is a combination of high performance concrete minerals admixture and steel fibers. The compressive strength reaches beyond 150 MPa which allows the construction of sustainable and economic buildings with an extraordinarily slim design.

Foam concrete solidifying in natural conditions significantly shrinks which causes deterioration of the porous structure and thus the increase in the heat conductivity of the material. One of the solutions for this problem is application of mineral modifiers. As the mineral modifiers the authors used the production waste – mineral additives wollastonite diopside at natural dispersive .
The range of concrete formulas used in the industry has expanded significantly in recent years. The BHS twin-shaft batch mixer type DKX is a reliable and future-proof solution for all concrete requirements. Batch after batch the twin-shaft batch mixer reliably produces extremely coarse-grained mixtures e.g. RCC very fine-grained materials with large amounts of admixtures e.g. SCC .
