Development of Mechanical Properties of Cement Paste with Different Addition of Polyvinyl Alcohol

摘要

This paper deals with using a resonance method for determining the development of the mechanical properties of a cement paste with different polyvinyl alcohol content. Main properties which were monitored are the dynamic Young's modulus and the dynamic shear modulus. Those properties were measured during 161 days for better understanding of influence of Polyvinyl Alcohol (PVA) added in the cement paste. Difference between this paper and the already published articles is in several parameters. Main difference is that samples in this paper were cured on air, not in water. Moreover, a higher amount of polyvinyl alcohol was used on the modification of the cement paste.
