DURABILITY OF CONCRETE

The results are presented of studies on uniaxially restrained, air-entrained concrete prism after immersion in sulphate solutions. Type S cement showed the greatest surface deterioration and that of type M showed greatest expansion. S and M cements showed much greater expansion than types K and V. The results are explained on the basis of the formation of ettringite. In another research effort, the condition was investigated of 69x69x42 - inch concrete blocks submerged for 67 years in the San Pedro, Calif. harbor. Visual examination and x-ray diffraction results are reported. A method is also reported for studying the sulfate resistance of portland and other types of cement recommended for use in locations subjected to attack by sulfate.
