Refractory castables are used for__________________?
Correct answer: C. All A., B. and C.
- A. Producing monolithic linings
- B. Patch work
- C. All A., B. and C.
- D. Minimising the number of joints in the structure
Explanation
Castables are refractory concretes that form monolithic linings, are convenient for patching damaged areas, and reduce the number of joints compared with brickwork. Therefore all three uses apply.
