MOISTURE STATE FOR A STANDARD CREEP TEST
Accurate control of concrete moisture conditions during a creep test is difficult; the choice of condition is either saturated or totally sealed. Saturated storage provides a definite moisture state but is inconvenient particularly in site use. Effective sealed storage can be given by an impermeable plastic, rubber or metal foil jacket, giving a more realistic moisture state. Sealed specimens are more convenient to handle, load and measure; they can be stored on site for direct comparison or prediction of structural behaviour. Control specimen strains are small requiring only small corrections to be made to creep specimen strains. For these reasons sealed storage is preferred, but since drying is excluded from the standard test it is recommended that weight changes should be checked to identify any abnormal drying behaviour. /TRRL/
