What properties of mortar can redispersible polymer powder ...

Redispersible polymer powder can significantly improve the bond strength of mortar. The greater the amount is added, the more it will be improved . High bond strength can have a certain inhibitory effect on the contraction, while the stress generated by deformation is easily dispersed and released, so the bond strength is very important to improve the crack resistance.
