The aim was to determine systematically the granulometric influences of the main constituents Portland cement clinker (K), limestone (LL), blastfurnace slag (S) and fly ash (V) as well as the substance-specific impacts of the particle size distributions on cement, mortar and concrete properties.
The present research project intended to systematically examine the effects of the cement type on the drying behaviour of cement-bound screeds. The particular aim was to establish whether the use of CEM II and CEM III cements really affects the drying behaviour of cement screeds.
The research project aims to investigate whether the limitation on use of recycled water in ready-mixed concrete works for air-entrained and high strength concrete that is in place in all three involved countries is justified, or whether it could be abolished.
The aim was to facilitate an efficient use of the new cements in high-performance and durable concretes, while taking into consideration the availabilities and origins of the cement constituents.
The aim of the investigations was to answer the question as to whether the K-S-LL system can be used to manufacture durable concretes using clinker-efficient cement under framework conditions that still need to be defined.
One of the aims was to compile ‘Guidelines for the use of crushed sands (fine RC aggregate) in the production of cement ̓ – referred to in the project as ‘R cement ̓.
The overriding aim is to actively promote innovative developments on future-oriented markets in Germany. The building industry is one of these.
In this research project the additional amount of freezable water in concretes consisting of cement with several main constituents and the influence on the critical saturation of the concrete were examined.
