Water absorption of recycled aggregates: Measurements, influence of temperature and practical consequences
F Théréné, E Keita, J Naël-Redolfi… - Cement and Concrete …, 2020 - Elsevier
Abstract Recycled Concrete Aggregates are highly porous and may therefore absorb more
water than natural aggregates. Several methods allow for the measurement of water …
