Composition for producing concrete, in particular lightweight porous concrete and high-performance concrete, mortar, self-leveling mortar and mastic, and method for the production and use thereof

Abstract

The present invention relates to a composition for producing concrete, in particular for producing lightweight porous concrete, self-leveling mortar, 3D printing mortar, or putty, characterized in particular by the fact that the amount of liquefying and / or retarding agent is in each case in the range of 0.05 to 2.00% by weight, based on the total weight of cement, and wherein the composition has a wet density in the range of 100 to 1250 kg / m³ for lightweight porous concrete, a wet density in the range of 1800 to 2200 kg / m³ for 3D printing mortar, a wet density in the range of 2000 to 2200 kg / m³ for self-leveling mortar, and a wet density in the range of 1900 to 2000 kg / m³ for putty. The invention also relates to the concrete produced by drying the composition, in particular lightweight porous concrete, self-leveling mortar, 3D printing mortar, or putty.An additional objective of the invention is a method for manufacturing these compositions and their use as concrete, in particular as lightweight porous concrete, as self-leveling mortar, as 3D printed mortar, or as putty.
