Ultimate shrinkage modeling of recycled aggregate concrete

Abstract

Data of recycled aggregate concretes shrinkage used to produce a linear model was proposed to predict the ultimate shrinkage. The fine and coarse recycled aggregates were made from crushed and sieved concrete, mortar and red ceramic. The proposed model shows the ultimate shrinkage of all recycled concretes are greater than the referential concrete. According to the proposed model, the recycled mortar fine aggregate is the most influential aggregate and the recycled mortar coarse is the less influential one in affecting the ultimate shrinkage of recycled aggregate concrete.
