Investigation of a Reaction Involving Nondolomitic L+IMESTONE Aggregate in Concrete, ?<2)Alan D. /Buck
Abstract
The presence of rims, indicating a chemical reaction, was noticed on the edges of limestone coarse aggregate particles in concrete cores taken from structures in Kansas and Nebraska. The rims were characterized by a color variation and by being more soluble in dilute acid than the interior of the rock. The characteristics of the reaction and of the rock indicated that this phenomenon was a previously unreported reaction of limestone in concrete. Seventeen limestones were used in a laboratory study which attempted to answer the following questions: Can the reaction be produced in laboratory experiments; What are the necessary conditions for the reaction to occur; Is the reaction harmful, and What is the mechanism of the reaction.
