AI Technical Summary

Technical Problem

Existing concrete compositions do not account for ambient temperatures on construction sites, leading to inefficiencies and limitations in achieving desired densities and properties.

Method used

A composition for producing concrete, including aerated lightweight and high-performance concrete, mortar, and fillers, utilizing specific cement types, additives, and liquid components that can be individually adapted to ambient temperatures, allowing precise dosing and production within a range of 0°C to 50°C, with components like plasticizers and retarders adjusted to ensure optimal processing and performance.

Benefits of technology

The solution enables concrete products with adjustable densities from 100 to 2600 kg/m³, enhancing workability and strength, and allows processing across varying temperatures, ensuring consistent quality and performance regardless of environmental conditions.

Abstract

The invention relates to a composition for producing concrete, in particular lightweight porous concrete, floating screed, 3D printing mortar or filler, which is characterized in particular in that the amount of plasticizer and / or retarder ranges, in each case, from 0.05 to 2.00 wt. %, based on the total weight of cement, wherein the composition has a wet density ranging from 100 to 1250 kg / m3 for lightweight porous concrete, a wet density ranging from 1800 to 2200 kg / m3 for 3D printing mortar, a wet density ranging from 2000 to 2200 kg / m3 for floating screed and a wet density ranging from 1900 to 2000 kg / m3 for filler. The invention also relates to the concrete produced from the composition by drying, in particular lightweight porous concrete, floating screed, 3D printing mortar or filler, and to a method for the production of said compositions and use thereof as concrete, in particular as lightweight porous concrete, as floating screed, as 3D printing mortar or as filler.
