With reference to the recent article 'Expanding their horizons' (NCE 12 October, Concrete special), I am surprised at the inaccuracy of the statement 'Britain's first joint free floor slab was poured in Scotland this summer'.
Although the merits of the expansive cement product mentioned were sufficiently documented in the article, approximately 1M. m 2of'jointless' concrete floor construction, using steel fibre reinforcement, in the UK ever year seemed to be conveniently ignored.
Since the introduction of steel fibres into the UK concrete flooring industry over 10 years ago and also the advent of laser screed methods, their use has become widespread, with both the technical advantages and practical benefits increasingly accepted by engineers and clients.
Without doubt jointless industrial concrete floors have an important role to play in British construction in the future as they do at present, but they are by no means something new.
