Sustainability | Free Full-Text | Mechanical and Durability Properties of Cement-Stabilized Recycled Concrete Aggregate


This analysis investigates the impact of utilizing recycled concrete mixture (RCA) as a partial substitute of pure mixture (NA) on the mechanical and durability-related properties of a cement-stabilized recycled concrete mixture (CSR) combination. On this case, mixtures have been ready with 0%, 40%, 70%, and 100% (by weight) RCA to interchange NA, and cement contents of 4%, 5%, and 6% have been used on this research. Take a look at parameters included the substitute ratio, cement content material, and curing time. Exams have been carried out to ascertain the unconfined compressive energy (UCS), oblique tensile energy (ITS), drying shrinkage, and water loss ratio of every combine proportion. The preliminary outcomes of UCS and ITS checks indicated that the incorporation of RCA resulted in a lower of energy in contrast with a cement-stabilized macadam (CSM) combination, however the seven-day energy of the CSR combination met the associated necessities of street bases. The rise in cement content material and curing time had an apparent impact on energy enchancment. The drying shrinkage take a look at confirmed that the drying shrinkage properties of the CSR combination have been clearly lowered with a excessive substitute ratio. It’s evident that the CSM combination introduced a greater drying shrinkage efficiency than that of the CSR combination.
