Compared with the control aggregate, the crushing strength could be increased by about 99% with the use of 2 wt% intermixed PVA. The enhancement of crushing strength was mainly related to the formation of polymer films in the aggregates [49]. The formation of cross-linked PVA films can enhance the bonding between the solid waste particles.
