CLEANKER – Integrated calcium looping process for CO₂ capture

The aim of the CLEANKER (CLEAN clinKER) project is to perform large-scale testing of this technology as an integrated method (Technology Readiness Level 7). It is planned to treat 4 000 m³/h exhaust gas in a demonstration plant to be connected to an existing kiln line at the Buzzi Unicem works in Vernasca in Italy.

Development of a method to improve clinker cooling and to increase energy efficiency in cement rotary kilns by using infrared cameras

In the research project, infrared cameras are used to record the surface temperature of the clinker bed in the clinker cooler. Together with calculated enthalpy flows, this allows control room personnel to identify the operating condition of the cooler. This is used in operational tests to optimise the heat transfer in the clinker cooler by controlling the drive system and adjusting the cooling air distribution.

Process engineering investigation of the energetic-material utilisation of wastes containing carbon fibres in cement plants - EVCAZ

In the AiF project EVCAZ, the energetic and material utilisation of wastes containing carbon fibres is to be demonstrated on an industrial scale in a cement plant. The central tasks are the evaluation of the conversion success of the CF fibres, the recording of the resulting emissions and the consideration of influences on the process and the clinker quality. The findings obtained are summarised to assess health and environmental risks and to answer questions relevant to approval as a decision-making aid for cement plant operators.

Cement clinker production with simultaneous power generation

The core concept of the research project is to generate the maximum amount of electrical energy from the process exhaust gas during the production of cement clinker without affecting its kiln capacity or clinker quality. The electricity generated should cover the base load requirements for the cement production.

Durability of concretes with clinker efficient cements under modified concrete technological conditions

The current research project aims to determine if CEM II/C-cements can be used in some exposure classes (XC1-4, XF1) according to DIN 1045 2 under modified technological conditions of the concrete (reduced water-cement ratio, increased minimum strength class) without additional requirements.

Proof for durability of chemically stressed concretes and concrete components: Proof of concrete attacked by carbonic acid

In order to be able to use new, clinker-efficient cements and concretes in the future even under the attack of carbonic acid, the development of a test and assessment concept is necessary. Therefore, VDZ and the Institute for Building Research of the RWTH Aachen started a joint research project.
