High-performance concrete

Mixing expertise

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, UHPC) or extremely low-slump consistencies (e.g., face concrete). Concrete additives and admixtures are quickly, evenly and effectively dispersed, even when only added in small amounts.

The speed of the mixing tools can be adjusted during the mixing process via a pole-changing motor or a frequency converter. In this way, hybrid mixing processes (slow – fast – slow) are also possible.

The mixer can also be configured for gas-tight operation to enable vacuum mixing. Another option is a twin mixing system, which increases the shear forces exerted on the mixture.

We offer a range of components for precise monitoring of the mixing process: sensors for measuring consistency or temperature, a device for taking samples, or a television camera. Thanks to its design, the twin-shaft batch mixer delivers extremely reliable monitoring results. We will happily perform tests at our technical center in Sonthofen.

Floating concrete batch plants for one of the widest bridges in the world in currently the biggest infrastructure project in the USA

The members of the "Tappan Zee Constructors" consortium use twin-shaft batch mixers from BHS-Sonthofen at the construction site of the biggest bridge in New York, the new "New NY Bridge". Altogether, the consortium uses seven mixers for mixing a total of 220,000 m³ of concrete. Three of these are in operation on floating concrete batch plants.

Mixing special concretes

As a result of recent new developments throughout the concrete industry over the past years, the re-quirements placed on the concrete production process, as well as the complexity of the mixing tasks, have considerably increased. This situation confronts suppliers of mixing machines with the tasks of systematically acquiring new knowledge on the operation and the functioning of their machines, and of developing suitable solutions for the challenges that arise.
