Abstract
Tests on lightweight aggregate (Lytag) and gravel concrete beams under sustained loading are reported. It is shown that deflection and crack widths under sustained loads are greater in lightweight-aggregate concrete beams than gravel concrete beams and that when a proportion of the shrinkage had taken place before loading, ultimate deflections and crack widths are smaller than if no shrinkage had taken place.
