Increasing energy efficiency in the cement industry through training by means of virtual reality (VR)

The aim of IGF project 21619 is to develop a training simulator with which learners can independently solve typical process engineering tasks within a virtual reality (VR) environment, particularly in connection with ball mills.

FlashPhos: The complete thermochemical recycling of sewage sludge

Elemental white phosphorus (P4) is indispensable for key industries such as in the food and pharmaceutical sectors and is therefore a strategic raw material of high relevance. In the FlashPhos project, the sustainable production of white phosphorus using sewage sludge will be demonstrated on a large scale.

Optimisation of energy demand and product quality during grinding in the cement industry through the use of ceramic grinding media

The aim of the IGF project 21791 N is to better understand the influence of ceramic grinding media (balls) on the comminution process and the product quality during cement grinding in ball mills. The data will serve as a basis for designing and predicting the energy requirements and behaviour of grinding plants when using ceramic grinding media.

Optimisation and evaluation of process chains for chemical CO₂ utilisation for the emission reduction in the cement industry

To meet the ambitious climate protection targets by 2050, so-called CCUS technologies are required. In addition to CO₂ storage, the combination of CO₂ and hydrogen management offers the possibility of producing usable products. The combination of capture methods and methods of CO₂ utilisation results in a variety of possible process chains, the optimum of which depends on site-specific boundary conditions. The project analyses possible pathways in order to develop a supporting tool for strategy development for specific sites.

Concrete technology


Current

Durability of concrete according to the performance principle - classification of material resistance, production control (PC), conformity criteria and control (CC)

In this project, the systematic classification of the carbonation and chloride penetration resistance of concretes will be investigated. Based on these results, recommendations for action will be derived for production and conformity control within the framework of a performance-based durability concept.

Recycled clay brick containing materials as a raw material in resource efficient cements and durable concretes

The topic of the research project is the utilisation of brick-containing materials from the recycling of mineral construction waste. It is being investigated whether and how resource-efficient cements can be produced with processed brick-containing construction waste and reduced clinker content, thus reducing process-related CO₂ emissions.

LeptoCalc

The use of fines from concrete recycling plants as cement constituents is currently insufficiently investigated and requires further research. The basic prerequisite for the utilisation of the fines will be to be able to characterise the material properties as quickly and comprehensively as possible and to ensure a constant material flow. An essential part of the research project is therefore the development of a rapid test method with which the properties of these fines can be estimated, among other things, by measuring the residual reactivity.

Environmentally friendly railway sleepers with calcium sulfoaluminate cements

The research project will investigate whether the technical requirements for railway sleepers with CSA cements can be realised. Also, some basic links to standards (e.g. modulus of elasticity, creep and shrinkage in accordance with EC2) must be checked and ensured.

Interactions between siliceous fly ash or calcined clay as cement main constituent and superplasticizers based on polycarboxylate ether as well as their influences on rheological properties of fresh cement paste and fresh concrete

It was determined how the rheological properties and the consistency of fresh concrete can be improved by the adjustment of the type and proportion of fly ash or calcined clay in the cement to the clinker as well as the type and dosage of the superplasticizer.
