ASTM C482
Full Name
ASTM C482 – Standard Test Method for Bond Strength of Ceramic Tile to Portland Cement Paste
Scope
ASTM C482 outlines a standardized procedure for measuring the adhesive bond strength between ceramic tile and Portland cement paste. This test is critical for evaluating the durability and performance of tile installations, particularly in applications where tile is subjected to mechanical stress or moisture.
Test procedure:
- Substrate preparation: a portland cement paste is prepared and applied to a suitable substrate.
- Tile adhesion: ceramic tiles are adhered to the paste using the specified adhesive and curing conditions.
- Bond strength measurement: after curing, the bond strength is determined by applying a tensile force to the tile until it separates from the substrate.
- Data analysis: the measured force is used to calculate the bond strength in units of pounds per square inch (psi).
Key considerations:
- Adhesive type: the choice of adhesive can significantly influence bond strength.
- Substrate condition: the condition of the substrate, including its surface preparation and moisture content, can affect test results.
- Curing conditions: proper curing conditions are essential for achieving optimal bond strength.
