Answer 2

The four examples of non-combustible materials are – cement, concrete, pumice, and sand.  

Explanation:  

• Non-combustible means materials that do not get burnt or combusted when subjected to high heat. These materials do not, in any way support the combustion process.
• Therefore it does not give off toxic gases or vapors when are subjected to different kind of heat, fire and other extreme circumstances. Combustible materials are those that when subjected to fire or heat start burning.
