INFLUENCE OF BOUNDARY CONDITIONS ON SOFTENING OF CONCRETE LOADED IN COMPRESSION. FRACTURE OF CONCRETE AND ROCK: RECENT DEVELOPMENTS. PAPERS PRESENTED AT THE INTERNATIONAL CONFERENCE, UNIVERSITY OF WALES, COLLEGE OF CARDIFF, SCHOOL OF ENGINEERING, SEPTEMBER 20-22, 1989

A series of displacement-controlled uniaxial and triaxial compression tests were carried out to gain more insight into the reliability of the results of such test. The influence of different types of loading platen on the behaviour of concrete was investigated. Special attention was paid to the influence of shear stresses induced in the concrete specimen by the loading platens and the influence of rotation of the loading platens. It was found that both factors had a considerable influence on the softening behaviour measured. For uniaxial tests, greased rigid loading platens covered with teflon sheets had the least disturbing effect on the softening behaviour. The triaxial test results showed that various loading platens which impose minimal shear stresses on the concrete still influence the concrete behaviour. The scatter in these test results was significant. The tests in which the loading platens could rotate showed that concrete behaviour was affected considerably and that this behaviour should be regarded as a structural behaviour rather than a material property.(A) For the covering abstract of the conference see IRRD 829348.
