Influence of Polymer on the Coating of Hydroxypropyl Methyl Cellulose and Redispersible Polymer Mortars

A common problem of concrete coating is the setting, in addition to the resistance and among other common factors that influence the workability of the material in the coatings, in the investigation it is desired to add to the coating mortar the hydroxypropyl methyl cellulose and redispersible polymer looking for the improvement in the behavior of mortar in the coating, for a long time the coating mortar has been evolving to improve the quality of the designs of the constructions. This process led to creation of constant improvements in mortars, on the other hand cellulose and redispersible polymer are polymers that have had a good reaction in the behavior with concrete for constructions, the present research focuses on measuring resistance and setting of a mortar with polymers and a traditional mortar for coatings, comparing both mortars demonstrate the workability and mortar quality. The results show that the mortar with polymers has better quality and is more workable than traditional mortar, giving positive results in the resistance tests and setting. At the end of the research, it was possible to verify through the resistance test and setting that mortar with polymers is better when it is used in the lining of the internal and external walls.
