Performance Similarity of an SAE Latex and VAc/E type Redispersible Powder on Cement Mortar used on an Expandable Polystyrene Panel

摘要

The performance of a Portland cement mortar modified by styrene-acrylate emulsion (SAE) latex and vinyl-acetate/ethylene (VAc/E) copolymer type redispersible powder (RPD) were studied. Performance similarity was found in our comparative study on both mortars. Results suggested that optimum usage of polymer content is between 2～3% for both SAE and RDP modified mortar which would give the highest toughness and adhesion on the EPS panel. The chemical composition difference between SAE and RDP have less effect on the compressive strength, flexural strength of the mortar and adhesion strength on the EPS panel.
