CONCRETE CREEP STUDY

Creep and shrinkage characteristics were determined for concrete made with aggregates from three different sources. A 1200 psi (8 Mpa) load was applied to creep specimens at three different concrete ages, and maintained for a minimum of 77 days. Using best fit curve equations determined from the concrete tests, a prediction of creep and shrinkage for any period up to one year can be made with reasonable accuracy. Although certain properties of aggregate and concrete are indicators of potential creep, more satisfactory results can be obtained by measuring creep and shrinkage as outlined in the report, using concrete made with the ingredients and in the proportions to be used in a specific structure. /Author/
