Cement resistors are power resistors that are heat and flame resistant.

Cement resistors are made to handle a large amount of power flowing through it with it being undamaged by heat or flames.

If you are designing a circuit where a lot of current is being passed through a resistor and with it needing to be resistant to high heat and flame, cement resistors is a good design choice.
