By modification with waterretentive agents and organic bonding admixtures
one drymixed 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 antisagging 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
