Projects and Literature

Our main research topic is the CO2-reduced circular economy of mineral building materials. Basic solutions found within the framework of the Helmholtz research programs are to be proven in practice and must be scientifically, technically and economically developed to higher technology levels. To this end, we conduct joint research projects with partners from universities and industry, which are supported by various funding bodies.

Recycling cluster Autoclaved aerated concrete (AAC): Optimizing demolition and separation of post use AAC and new routes for circular use of AAC

Project duration 01.06.2019 – 31.12.2022

Abstract

The upcoming end of buildings life time within the next years will lead to increasing amounts of post use AAC material from demolition. The Repost project deals with ways of reusing such material batches within the production of new AAC to avoid landfilling and save primary resources.

R-Zement: low CO2 production of di calcium silicate clinker from recycled construction material

Project duration 01.04.2021 – 30.06.2025

Abstract

R-Zement project aims at a pilot plant to establish a decentralized clinker production at a 10t/h scale. The newly found process generates di calcium silicate clinker (belite clinker) at a temperature of 1000°C. At the pilot plant level the rotary kiln will be electrically heated.

An advisory board with members from Baden-Württemberg administration, industrial associations and companies is set up to guide the project.

Innovation pool project 1: Energy transition and circular economy: Decarbonation and flexibilization of energy intensive recycling processes

Project duration 01.01.2021 – 31.12.2023

Abstract

Using thermochemical recycling of waste concrete as an example to simulated implications on mass and energy cycles. What needs to be considered to maintain stable power grids and economic production with increasing amounts of renewables? What is the impact of decentral but energy intensive processes?

Ultraefficiency demonstrator for decentralized processes

Project duration 01.05.2021 – 31.12.2022

Abstract

This feasibility study deals with enhancing the circulation of materials, e.g. the demolition and material recycling of external thermal insulation composite systems (ETICS) in construction. The two main fractions, organic vs. inorganic, proceed to different value chains with chemical intermediates and mineral constructions materials as products. Ideally, a complete recycling is to be achieved and will be evaluated.

Low CO2 concrete by upcycling wastes from demolition

Project duration 01.11.2022 – 31.10.2025

Abstract

The aim of the project is the manufacturing of high quality and sustainable concretes with partial substitution of components by recycling products (RC) instead of standard cements and aggregates. Separately or in parallel substitution shall be achieved with

  • low temperature belite clinker (KIT process) added to OPC based cements and
  • mechanically prepared concrete fines.

A final test in the production of precast concrete parts will be based on the adapted clinker process, mix design and ratios, sulfate carrier and additives adjustment.
