EVALUATION OF SULFATE-RESISTING CEMENTS BY A NEW TEST METHOD

Standard specifications for sulfate-resisting cements and laboratory tests for evaluating the sulfate resistance do not take into account the acid-type sulfate attack associated with gypsum formation. A new laboratory test, which is quick and reproducible, was found useful in evaluating the resistance of cements to ettringite-type and gypsum-type attack. The test showed significant differences in relative sulfate resistance of Type V portland cements and blended portland cements. It is concluded that the sulfate resistance of cements depends not only on the total reactive aluminates present but also on the total Ca (OH) sub 2 present in the cement paste.
