STATE OF THE ART OF ROAD CONCRETE WITH PLASTICIZERS

DER ERREICHTE STAND DES STRASSENBETONS MIT FLIESSMITTELN

Road concrete incorporating plasticizers has been used in the Vienna area on a large number of small construction sites for the past two years. A gap graded mix 4/8 mm makes it possible to use a large proportion of skid resistant coarse chippings. When carrying out suitability tests, particular care must be taken that the particle size distribution of the sand fraction is defined carefully so tht the fresh concrete has high plasticity and a satisfactory bond. The plasticizer should, where possible, be added in proportions of not more than 3.6 kg/cu cm (0.9% of 400 kg/cu cm cement), because otherwise it may eliminate the artificial air voids. (TRRL)
