A comparative study of sustained loading effects on lightweight-aggregate and gravel concrete beams
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.
