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 target of this research project was to develop a comprehensive database regarding the material parameters carbonation and chloride resistance for different cement types and concrete compositions. The investigations focused on concrete compositions that contain cements with low clinker/cement factors.
This research project in the field of municipal traffic areas was aimed at basic findings for a practice-oriented classification of the moisture class and the respective assessment of concrete by means of a performance-test. For this purpose concrete pavements without showing signs of a damaging ASR after approx. 10 years of use were tested. From this pavements drill cores were taken and assessed with a procedure especially developed for the moisture classes WA.
This aim of this research project was to create a secured assessment background for testing the frost de-icer resistance of earth-moist produced concrete paving stones. The proposals could possibly be developed for testing in realistic conditions.
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.
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 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.
