Waste-Based porous materials as water reservoirs for the internal curing of Concrete. A review

This review collates findings from more than 100 scientific publications regarding the performance of several waste-based porous materials (WASPORs) as water reservoirs for internal curing concrete. Results obtained by using recycled concrete aggregates, crushed ceramics, coal bottom ash, artificial different powder and fibres were included. The influence these WASPORs on consistence, hydration, setting, microstructure, density, strength, modulus elasticity, autogenous deformation, drying shrinkage durability properties analysed. General recommendations suitable characterization WASPOR mix design are also given. differences in absorption capacity between studied have been used explaining observed phenomena. A moderate together with a quick desorption found to be among key factors that define efficiency proposed WASPORs.
