Effect of redispersible vinyl acetate and versatate copolymer powder on flexibility of cement mortar
Highlights ► VA/VeoVa powder increases the transverse deformation and fracture energy of mortar. ► VA/VeoVa powder increases the flexural strength markedly. ► The σ C/σ F of mortar was effectively reduced by VA/VeoVa powder. ► VA/VeoVa powder improves the flexibility of cement mortar significantly. ► Transverse deformation and σ C/σ F are complementary in charactering the flexibility.
Abstract The effect of redispersible vinyl acetate and versatate copolymer (VA/VeoVa) powder on the flexibility of cement mortar is studied using the methods of the transverse deformation and the ratio of compressive strength to flexural strength (σ C/σ F), to explore the possibility of these two methods in charactering the flexibility of VA/VeoVa powder-modified mortar. The transverse deformation and the fracture energy of the modified mortar increase significantly with the augment of the m p/m c, but the peak load decreases when the m p/m c is higher than 8%. 3% m p/m c makes the compressive strength decrease, but has no effect on the flexural strength; whereas when the m p/m c is higher than 5%, the VA/VeoVa powder increases the flexural strength markedly. The σ C/σ F depresses sharply with the m p/m c augmenting from 0% to 3%. The transverse deformation and the σ C/σ F are complementary to each other in charactering the flexibility of VA/VeoVa powder-modified mortar. VA/VeoVa powder improves the flexibility of cement mortar significantly.
