C113 - standard test method for Reheat Change of Refractory Brick C133 - standard test method for Cold Crushing Strength & Modulus of Rupture of Refractory C704- standard test method for Abrasion Resistance of Refractory Materials at Room Temperature

Abrasion, Testing Refractories for Resistance

The Modulus of Rupture (MOR) indicates the material bending strength and its suitability for use in construction. It depicts the strength of the bonding system of the refractory product, and is an important parameter for quality control and development of refractory linings. For the test a rectangular test sample is supported in span. The testing machine applies a load at a specific …

API 936 PRACTICE TEST Flashcards | Quizlet

Test Method: IS: 1528 (P-8)1974 Cold Crushing Strength Test: This test helps in determining the strength of a brick. It specifies how much load the refractory can bear in cold conditions. Metallurgy gave birth to this concept of testing CCS of refractory material.

ISO

Standard test methods do not necessarily give the most useful data. The cold crushing strength of a fired brick is generally much greater than its crushing strength at higher temperatures; rectangular blocks heated from one end do not expand as expected from the free thermal expansion; nor is the Young's modulus of a stressed block the same as ...
