ASTM C773 Compressive Strength of Fired Whiteware Materials

ASTM C773 determines the strength of fired whitewares, a class of ceramic product, usually white. A machine compresses a sample till it breaks. The breaking force is then used to calculate the strength of the sample.

Frequently Asked Questions

ASTM C773 determines the compressive strength of fired whiteware materials. It evaluates the ability of ceramics to withstand crushing loads, helping assess structural integrity and suitability for load-bearing applications.

Key parameters include applied load, specimen dimensions, loading rate, and surface condition. Proper alignment and preparation ensure accurate measurement of compressive strength under controlled conditions.

The test measures maximum compressive load and calculates compressive strength. Results indicate resistance of ceramic materials to crushing and mechanical failure.

ASTM C773 is used for fired whiteware materials such as tiles, sanitary ware, and ceramic components used in construction and household applications.

ASTM C773 is conducted under controlled laboratory conditions and may not fully represent real-world performance where factors such as flaws, environmental conditions, and loading variations influence material behavior.
