OCCURRENCES OF EXPANSIVE LIMESTONE IN KENTUCKY

Research Report 325, "Expansive Limestone Aggregate in a Concrete Pavement", April 1972, remains a worthy, preliminary treatise on the two, principal roles of limestone aggregates in the premature deterioration of concrete. The role addressed more directly here, and there, is the expansion of clayey dolomitic limestones. The other role, of course, is freezing and thawing of porous, nearly saturated, otherwise non-expansive, aggregate in the concrete. It is desirable to be able to associate unsoundness with properties and composition and also with appearance, texture, and geological occurrence. Texture has been illustrated here and elsewhere. Scanning electron micrographs included here have some special qualities and significance not recognized heretofore.
