Introducing the cutting‐edge VBCC'S cold crushing strength instrument for refractories, meticulously developed to meet the rigorous standards outlined in (ASTM: C133 ‐ 97). Cold crushing strength is the most important physical property for ceramic materials especially for refractories which are used at high temperature. This VBCC'S cold crushing strength (ASTM: C133 ‐97) helps in determining the strength of a brick. It tells us how much load that refractory can bear in cold conditions. The VBCC'S cold crushing strength (ASTM: C133 ‐ 97) of a refractory material is an indication of its suitability for use in refractory construction. (It is not a measure of performance at elevated temperatures.)
Test Specimens
Brick and Shapes (bulk density greater than 1.60 g/cm3 ‐The test specimens shall be 51‐mm cubes or cylinders, 51 mm in diameter by 51 mm high. The height should be parallel to the original direction of pressing of the brick or shape. In the case of special shapes, only one specimen shall be cut from a single shape and as many of the original surfaces as possible shall be preserved. In preparing specimens from irregular or large refractory shapes, any method involving the use of abrasives, such as a highspeed abrasion wheel, core drill, or rubbing bed, that will produce a specimen with approximately plane and parallel sides without weakening the structure of the specimen may be used.
Insulating Brick or Shapes (typical bulk density of 1.60 g/cm3, or greater than 45 % total porosity, or both. The test specimens shall be 114 by 114 by 64 or 76 mm, each taken from a different brick. Castable Refractories‐The test specimens shall be 51‐ by 51‐ by 51‐mm cubes or cylinders 51 mm in diameter by 51 mm high, prepared by casting or gunning.
For dense refractories with sufficient strength to require greater than about 3 min per test, initial loading to one-half of the anticipated failure load may be accomplished at any convenient rate exceeding the specified rate. Subsequently, each specimen shall be crushed with a compressive load applied at the standard rates
Calculate the cold crushing strength using Eq S = W/A, where:
S = cold crushing strength, MPa
W = total maximum load indicated by the testing machine
A = average of the areas of the top and bottom of the specimen perpendicular to the line of application of the load.
