Optimisation of the Mixing Process for Producing Self-Compacting High-Performance Concrete

Today’s concrete structures call for high-tech construction materials, for example self-compacting high-performance concrete (SCHPC) as self-compacting high-strength concrete (SCHSC) and self-compacting ultra-high-strength concrete (SCUHSC). These concretes are defined as concretes with special properties. This development aims to increase the packing density through the selection of coarse and fine aggregates combined with a reduction in the water-to-binder ratio (

w/b

). To achieve this goal, state-of-the-art concrete plants need to meet certain minimum requirements. In an effort to realize shorter construction times and develop new concrete process technologies, and in view of ever-increasing degrees of component loading, international research has been going on for approximately 30 years for materials that have led, among other things, to the development of high-performance concrete. A trend towards the development of customized concretes, for example of SCHPC, can also be observed in the German construction industry.
