Finally, a correction coefficient for the shrinkage strain of RAC, \(\xi _\), to be used in conjunction with the fib Model Code 2010 model, was proposed in the form of a bivariate power function with RAC compressive strength and RCA replacement ratio as variables.ĪCI 2092R–08 (2008) Guide for modeling and calculating shrinkage and creep in hardened concrete. Applying the fib Model Code 2010 shrinkage prediction model revealed that, relative to its performance on NAC, the shrinkage strain of RAC is underestimated.
This difference increases with increasing recycled concrete aggregate (RCA) content and with decreasing compressive strength. A comparison of RAC and companion NAC revealed that, on average, RAC displays a larger shrinkage strain. Results from 19 studies entered into the database, consisting of 125 shrinkage curves (39 NAC and 86 RAC) with a total of 424 data points. For this purpose, a database of experimental results on the shrinkage of RAC and companion natural aggregate concrete (NAC), produced with the same water-cement ratio, was compiled using strict selection criteria. The study aims at providing an analytic expression for the shrinkage strain of RAC to be used in conjunction with the existing fib Model Code 2010 shrinkage prediction model. This paper describes a meta-analysis of previously published studies on the shrinkage strain of recycled aggregate concrete (RAC).
