The Influence of Regenerate Styrene Acrylic Emulsion on Thin Layer of Toughening Cement Mortar used on an Expandable Polystyrene Panel

摘要

Studied the waste expandable polystyrene (EPS) foam to reproduce styrene-acrylate emulsion (SAE) latex and applied in cement mortar. The results showed that the increase content with regenerate SAE, the amount of water used in mortar was decreased and the water reducing rate was increased gradually, the pull-off strength was increased. When the regenerate SAE content is 3% by weight, the destruction formation of EPS panel and the SAE modified cement mortar showed cohesive destruction, confirmed the toughness and adhesion of the cement mortar and EPS panel was improved. The ratio of compression strength and flexural strength were decreased with the increase content with SAE, after that had a slight growth. The ratio of compression strength and flexural strength was minimum when the SAE content is 3.5% by weight which suggested the optimum regenerate SAE content in this study.
