Experimental and Estimated Evaluation of Drying Shrinkage of Concrete Made with Fine Recycled Aggregates

Using fine recycled concrete aggregates (FRCA) in manufacturing points towards achieving sustainability aggregate valorisation. The higher absorption and amount of hardened cement paste FRCA may impair performance. One the most influenced properties is drying shrinkage; this because extra content porosity deformability when compared to natural sand. Thus, influence on shrinkage appears depend quality how its considered during mix design. In study, mineralogy evaluated, also considering compensation rates. addition, feasibility different models predict ultimate analysed. water cause effects according property evaluated. storage inside particles causes no (or even a beneficial influence) concretes. Models used estimate show they are still reliable with use FRCA.
