Some tests on the transmission length and ultimate strength of pre-tensioned concrete beams incorporating Dyform strand Available to Purchase

Tests were carried out on 24 beams pre-tensioned with Dyform strand and 6 beams pre-tensioned with standard strand, to determine and compare transmission length, flexural strength and behaviour. It was found that the transmission length was greater for specimens incorporating Dyform strand than for those with standard strand, both at transfer and after a period of some months. Ultimate load tests indicated that the flexural behaviour of the two types of specimen was similar.
