Polyvinyl alcohol (PVA) has undergone intensive research work that has led to confidence in its utilization in various applications.
Nevertheless, its utilization as a construction material in the concrete industry still needs to be fully addressed.
In this paper, an experimental study was dedicated to investigate the influence of PVA on the fresh and hardened properties of concrete.
Three different strength grades, represented by water to cement ratios (w/c), of 0.4, 0.5 and 0.6, with four different PVA dosages of 1, 2, 3 and 4%, by mass of cement, were employed in the preparation of the concrete mixes.
Concerning the fresh properties, results showed that there was a significant contribution of PVA to the workability in all produced mixes, irrespective of w/c ratio.
In addition, the initial and final setting time of cement pastes modified with 2% PVA were longer than that of the control paste.
In term of the hardened properties, results demonstrated that the compressive (fcu) and splitting tensile (fst) strengths of concrete are dominated by amounts of PVA in the mix and w/c ratios.
With the high and moderate w/c ratios, they increased when up to 2% PVA was used, and thereafter decreased.
However, with the low w/c, PVA did not provide any improvement in the strength, but instead, it decreased the strength when more than 2% was added.
The findings revealed also that increasing PVA content resulted in a significant reduction in total water absorption (TWA) of concrete specimens.
The larger the PVA contents the lower is the TWA of the specimens
