SALT SCALING RESISTANCE OF CONCRETE CONTAINING HOLLOW PLASTIC MICROSPHERES

A limited laboratory study was carried out to determine the effect of various amounts of hollow plastic microspheres (Kleenopor SA-8) in portland cement concrete on its resistance to freezing and thawing in presence of deicing salt. The performance of concrete containing 0.3 to 2.4 percent Kleenopor SA-8 was compared to that of air entrained concrete. The study indicated that a dosage of at least 1.2 percent Kleenopor SA-8 by mass of cement is needed to give the concrete salt scaling resistance similar to that of conventional normal slump air entrained concrete. The addition of such a large amount of Kleenopor SA-8 would substantially increase the cost of the concrete and make its use uneconomical. (Author)
