Entwicklungskonzepte für robuste Ökobetone

Abstract

Beton ist der weltweit meist verwendete Baustoff und eines der meist produzierten Güter überhaupt. Seine Produktion in solch großen Mengen erfolgt jedoch unter erheblichen Eingriffen in die natürliche Umwelt, die sowohl signifikante Beiträge zu den anthropogenen CO2-Emissionen wie auch regionale Verknappungen der mineralischen Betonausgangsstoffe beinhalten. Ökobetone müssen sowohl eine verbesserte CO2-Bilanz aufweisen wie auch gegenüber Schwankungen in der Qualität ihrer Ausgangsstoffe robust sein, das heißt die für sie bestimmten Frisch- und Festbetoneigenschaften mit hoher Sicherheiz erzielen. Die granulometrischen Eigenschaften der Ausgangsstoffe und die Zusammensetzung der Gesteinskörnungen spielen hierfür eine zentrale Rolle. Dieser Beitrag erläutert Ansätze zur Entwicklung rheologisch robuster Ökobetone.

Concrete is the most used construction material and one of the most produced goods of all. Its production in such large quantities causes great environmental impacts, including significant contributions to anthropogenic CO2-emissions and a decrease in the regional availability of high quality constituent materials. Green concretes must demonstrate an improved CO2-balance over their lifecycle and yet also be robust against variations in the quality of their constituent materials, meaning the desired properties of the concretes must be achieved with a high level of certainty. The granulometric properties of the aggregates are central to this challenge. This paper explains development procedures for rheologically robust concrete mixtures.
