Title:
STUDY OF CREEP IN CONCRETE. PHASE 1, (I-BEAM).

Abstract:
A practical method is determined whereby reasonably accurate estimates of creep and shrinkage of full-sized concrete structures can be obtained. Tests have been conducted on concrete cylinders placed in storage environments with controlled temperature and relative humidity. The most generally accepted findings about concrete volume changes were applied to the test data obtained and equations were developed that very closely fit observed data. It is concluded that 1 Timedependent strain measured on a loaded specimen total creep is the result of viscous flow viscous creep and seepage of gel water seepage creep. 2 Timedependent properties of a structure of any size and shape can be estimated using the techniques and equations developed herein for a concrete mix identical to that used in this study. 3 Time-dependent properties of any other type of normal weight concrete mix can be predicted following short-time creep tests up to 90 days using the actual concrete mix for the proposed structure.
