Influence of intensive vacuum mixing on the compressive strength of cementitious materials

abstract
In the last decades the quality of cementitious materials increased enormously. New high performance construction materials such as Self-Compacting Concrete (SCC) and Ultra High Performance Concrete (UHPC) made it possible to build faster, higher and more elegant. Structural engineers are using the properties of these new materials up to the maximum performance possible. This means that a small variation in mechanical, rheological or durability properties can have a big influence on the final construction. For this reason the concrete industry shows a great interest in technology that can lower this undesirable fluctuations. One aspect is the uncontrollable air inlet during the mixing of the concrete. For this a lowered pressure in the mixing pan can be of great use. A vacuum mixer can control the air inlet during mixing and even lower the air content of the final product. This could have a positive effect on the mechanical properties such as the compressive and tensile strength and Young’s modulus. This paper will try to verify whether this new type of mixing can have a positive effect on the compressive strength of cementitious materials.
