Abstract
Abstract. This paper presents an experimental study on prediction of the early-age creep and shrinkage
of concrete with and without silica fumes, trass, ground-granulated blast-furnace slag, combinations
thereof, and in
uences of the proposed Iranian pozzolans. Experiments were carried out under a controlled
ambient condition at a temperature of 40C and a relative humidity (RH) of 50%, and a laboratory ambient
condition at a temperature of 20C and a relative humidity (RH) of 30% in order to collect the required
data. Comparisons are made between ACI209-92, BS8110-1986 and CEB1970 prediction models, and an
estimation model, based on 28-day results (short-term test method), using the same experimental data to
predict the creep and shrinkage of the specimens at the ages of 120 and 200 days after curing. The results
show that the above-mentioned models are not accurate enough for predicting the creep and shrinkage of
concrete containing local Iranian pozzolans. It was also observed that the prediction, based on short-term
results, would lead to more accurate creep and shrinkage predictions.
