Adeyemi Adesina

PVA are used to improve the bond strength between the aggregate and the paste, and also ensure that the thickness of the ITZ is reduced

Aymen J Alsaad

PVA use as adhesive for construction materials and when use in concrete will decrease of the workability of fresh mixture because of its high viscosity, increasing the amount of PVA will increasing porosity.
