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.

Clinker burning with alternative fuels at low process temperatures - effects on coating formation and on the corrosion of refractory products in the cement rotary kiln as well as on the performance of cement

The replacement of primary fuels by alternative fuels is of great economic and ecological importance for the cement industry and is to be increased in the future. The fuel ashes are used as raw material in the cement clinker and influence its properties as well as the coating formation on the refractory lining in the kiln. Exact knowledge of these effects is indispensable for the further increase of the alternative fuel rate and the simultaneous optimisation of the kiln operation as well as for the maintenance of the clinker quality and the service life of the refractory lining.

The aim of the research project is to investigate the suitability of previously largely unused mineral secondary raw materials from the stone and earth industry as a resource-conserving and climate-friendly main cement constituent. The use of cal-cined clays from secondary raw materials instead of conventional main cement constituents or high-quality primary clays can make an important contribution to the production of climate-friendly and resource-efficient cements.

Interactions of accelerating admixtures and clinker-efficient cements with several main constituents to improve the early compressive strength of concrete

The acceptance of resource-efficient cements with significantly reduced specific CO₂ emissions is still too low in construction practice. The main reason for this is that early strength is not high enough for economical production processes and also competitive construction with concrete. Accelerating admixtures can improve the early strength of concrete. The research project investigates interactions between concrete admixtures that accelerate the strength development and cements with several main constituents.

Influences of two-stage mixing on the hydration behaviour of Portland-composite cements and composite cements as well as on the concrete performance
