Effect of Poly(vinyl-alcohol) amount on flexural strength of cement mortars with micronized recycled concrete
Original language description
Main goal of the presented study was to investigate the influence of different curing conditions and different amount of PVA (Poly(vinyl-alcohol)) on flexural strength of cement-PVA composites. Resulting cement-PVA composites was composed of Portland cement CEM I 42.5 R, micronized recycled concrete and PVA with different percentage amounts (0 wt. %, 1.4 wt. %, 2.8 wt. %, 4.0 wt. % and 5.6 wt. %). Two sets of samples were made from each mixture. The first set of samples was stored in water after their removal from molds, while the second set was stored exposed to air at a constant temperature and relative humidity. The flexural strength was measured on samples of size 40 x 40 x 160 mm using a three-point bending test. The results obtained from these materials were compared with reference material.
