Sulfate-Resistant Concrete. Literature Review,
Abstract
A limited review of technical literature was made to determine the present state of knowledge concerning: (a) nature and mechaniem of sulfate attack on concrete; (b) methods of minimizing or preventing sulfate attack; and (c) methods of guarding or restoring existing structures affected by sulfate attack. The information obtained showed that, generally, the degree of sulfate attack on a concrete structure is dependent upon: (a) type of cement used; (b quality of concrete with regard to sulfate resistance; (c) local conditions (sulfate concentration in soil and ground water); and (d) surface protection. Before the structure is built, local conditions should be studied to determine the need for using Type II or V, or special cements, or for addition of pozzolans. In sulfate attack is expected, the quality of the concrete is of paramount importance. Surface coatings may be used as a precaution but cannot be substituted for good-quality concrete. After the structure is in place, surface coatings and adequate drainage are the only means of protecting the concrete from sulfate attack. (Author)
