- Abstract
By modification with water retentive agents and organic bonding admixtures, one dry mixed superfine sand mortar used as ceramic tile bonding was prepared with good workability, adhesive capacity and climate resistance. The test results indicate that this mortar has excellent anti sagging characteristics, with slippage of less than 2mm, sufficient open time and bonding strength over 1 MPa after being open for 20 minutes. These traits provide the needed qualities for thin construction of ceramic tile bonding. By adding polypropylene fiber, a flexible mortar was prepared with superior crack resistance for use as a ceramic tile bonding agent. The preparation mechanism, method and performance are introduced in detail.
