CREEP OF STRUCTURAL LIGHTWEIGHT CONCRETE SUBJECTED TO LOADING AT AN EARLY AGE

KRIECHEN VON KONSTRUKTIONSLEICHTBETON BEI FRUBZEITIGER BELASTUNG

Long-term loading tests were carried out on two types of structural lightweight concrete (compressive strength 415 kp/sq cm and 550 kp/sq cm) containing expanded clay aggregates, to study the behavior of concrete under creep conditions. The load was applied at 4 different ages when the concrete was between 1 and 8 days old. The samples were kept under various humidity conditions. Final creep values decreased with an increase in the age of the concrete at the time of load application when the concrete was between 1 and 4 days old. If loads are applied when the concrete is over 4 days old, the final creep value remains constant. Deformations caused by shrinkage were not proportional to creep duration. In all cases, samples not subjected to loading, showed signs of swelling deformations. /IRRD/
