Effect of Polymer on Antifreeze Properties of Cement Mortar

摘要

Owing to the disadvantages of traditional mortar with poor antifreeze property, low adhesive strength and short durability in the cold region of China, the facing tiles often fall off and lead to the lost of decorative effects and protective effects. In this article, a new type of mortar for exterior wall facing tile, polymer cement mortar modified by polymer, is introduced. The advantages of the new mortar are: (1) Better frost resistance, which is reflected by stability after one hundred cycles of freezing and thawing; (2) Higher adhesive strength (2.0MPa); (3) Better permeability resistance and longer durability. It is believed that an ideal building mortar for the resistance of frost damage and suitable for exterior wall facing tile.
