✦ Synopsis
The stress-strain-relationsof lightweight concrete published so far differ greatly in shape and ultimate strain. In some cases the curves experimentally obtained are similar to those of normal-weight concrete, in other cases they are very stretched compared to normal-weight concrete. The scatter of the measured values of the ultimate strain of lightweight concrete is greater than the scatter found with normal-weight concrete.
It could be shown that the shape of the stress-strain-relation of lightweight concrete also depends on ultimate stress as well as on the type of lightweight aggregate.
Furthermore the ultimate strain measured under constant rate of strain is obviously influenced by the type of aggregate and by the strength of concrete. An explanation of the deviation from normalweight concrete is given.
