Trade Journals for the Concrete Industry

The outstanding properties of ultra-high performance concretes became well known in Germany after the construction of the Kassel family of bridges [1;2;3], including the Gärtnerplatz bridge and a number of monolithic bridges over the River Nieste. Today, pn account of its superior strength, surface properties and high sustainability [4], UPHC is not only used for large individual constructions with individual approval, but also in the manufacture of standard components. The use of binding agent and concrete compounds for the production of these concretes in a precast facility is also well-known. It is worth looking at the manufacture of ultra-high-strength concretes using local raw materials, both from the environmental point of view and even more with regard to cost. This kind of production gives a precast facility the greatest degree of autonomy in the composition of the material and how it is used. The following examples are designed to provide an insight into the possibilities for the development of ultra-high performance concretes with different properties, made with the raw materials usually used by precasters.
