Abstract:
Results of some studies on lightweight aggregate concretes made by the National Bureau of Standards at the request of the Housing and Home Finance Agency (formerly the National Housing Agency) are reported in this paper. Aggregates studied were expanded clay, shale, and slate; three types of expanded blast-furnace slag; expanded vermiculite and perlite; sintered diatomite and flyash; and a pumice. Concretes of arious proportions were made from these aggregates and determinations were made of the weight per cu foot, compressive and transverse strength, shrinkage, elastic modulus, absorption, resistance to freezing and thawing and thermal conductivity. Test results are briefly discussed and summarized.
