Estimating long-term creep and shrinkage from short-term tests

Synopsis From experimental results on a range of mixes made with two lightweight and two normal-weight aggregates and from an analysis of numerous data of other investigators, it is proposed that creep and shrinkage at one year can be predicted from measured values at between 7 and 28 days by means of linear and power equations. Equations for the prediction of longer-term values are also given.
