DEICER SALT SCALING RESISTANCE OF ROLLER-COMPACTED CONCRETE PAVEMENTS. IN: DURABILITY OF CONCRETE. SECOND INTERNATIONAL CONFERENCE. AUGUST 4-9, 1991, MONTREAL, CANADA. VOLUME I

As part of an extensive investigation of the durability of roller-compacted concrete pavements, 28 different concrete loads were cast during the summer of 1988. Four types of cement (CSA types 10, 30, 10 + silica fume and 10 + fly ash), two different sands (one natural and one manufactured) and two water to cement ratios (0, 27 and 0, 35) were used to prepare these mixtures. An air-entraining agent was added to half of them. Results indicate that it is extremely difficult to entrain air in this type of concrete even if fairly large dosages of air-entraining agent are used and mixing time is increased. Despite the lack of spherical air bubbles, good scaling resistances were obtained with the silica fume and the fly ash concretes prepared with the natural sand and cured with a membrane.
