"Elasticity, Creep, and Shrinkage of Concretes Containing Admixtures"

This paper assesses the general effects on elasticity, creep and shrinkage of concrete arising from the use of admixtures: plasticizers, superplasticizers, slag, fly ash and silica fume. Previously published test data are collectively analyzed to quantify creep and shrinkage of concrete containing the admixture as a proportion of creep and shrinkage of concrete containing the admixture as a proportion of creep and shrinkage of plain concrete having the same mix proportions. The analysis shows the effects of admixtures are very highly variable and the expressions given for predicting deformations are only recommended in the absence of test data.
