Main focus of our services

Alongside comprehensive material characterisation, we can also advise you on product optimisation aspects. You benefit from our in-depth knowledge, our wide range of services and our extensive equipment. Our experienced experts assist you with recording and assessment of the current situation at your plant and investigate the influence of burning and cooling conditions, as well as of raw materials and fuels, on the clinker properties. Our laboratories conduct studies, for example on the performance of cements and cement constituents, as well as on sulphate resistance and the effectiveness of chromate reducers. We assist you with the planning, execution and assessment of your operational trials and conduct preliminary trials to obtain approvals (e.g. durability forecasts employing parameters based on the degree of hydration). We offer expert advice and the development of ideal, practicable solutions.

To the service

Calcined clays

The use of calcined clays as cement main constituent or as concrete additive is becoming increasingly interesting from both economic and ecological points of view. Benefit from our long years of experience in the field of evaluating clays for use in cement and concrete. We accompany you from the selection of suitable deposits to the quality assurance of your new product.

To the service

Characterisation of Portland cemtent clinker

The analysis of Portland cement clinker allows profound conclusions on the clinker burning process and the behavior of the clinker in cement. It allows the identification of problems in the production process, the assessment of the influence of new raw materials and fuels and the optimization of clinker and cement quality. Benefit from our long-term expertise in the cross-method evaluation of clinker properties.
