EFFECT OF VARIOUS FACTORS ON THE EXTENSIBILITY OF CONCRETE

The control of cracking in dams and other massive concrete structures depends in part upon the amount of strain which the concrete can sustain in tension before cracking occurs, i.e. upon the extensibility of the concrete. Although creep has been widely studied in this connection it does not necessarily follow that high creep is associated with high extensibility since the latter is partly dependent on tensile strength. The present report contains a brief commentary on the relevant international literature and A select bibliography. One of the main conclusions is that extensibility should be studied directly, under controlled rates of straining simulating those in the structure, e.g. under conditions analogous to those already used in the determination of 'complete' stress/strain curves.(a) /TRRL/
