This project was also the basis of a widely accepted European guideline on Self compacted concrete published by the European industry association bibm, CEMBUREAU, EFCA, EFNARC, ERMCO, which again builds the basis of the European standards for the testing of SCC (EN 12350, Parts 8 to 12) as well as for the actual modernisation of the European concrete standard EN 206-1.

T1 - Cracked and uncracked SHCC specimens under different exposure conditions N2 - This paper describes the fibre-reinforced strain hardening cement-based composite (SHCC) performance under various exposure conditions. Cracked and uncracked SHCC beam specimens were subjected to cyclic wetting and drying under chloride exposure to observe the time of depassivation and corrosion potential of the imbedded reinforcement. Two reference mortars, one of the same strength class as the SHCC (Mortar 1) and the other of high strength class (Mortar 2) were used under the same conditions. Finally, tests for determining the rapid chloride migration coefficient, electrical resistivity, capillary water absorption and freezethaw were also performed to observe the corrosion probability and diffusion rate in uncracked SHCC and mortars.
