Firebrick Grog 0-5mm - 25kg

0-5mm graded and dried firebrick grog. Suitable for the roman block method of mould making. 

Crushed firebrick makes an excellent aggregate for a castable refractory, e.g. high heat refractory concrete. This type will survive in real high heat and can be used for hot-face applications.

The mix of Firebrick Grog, which is a refractory or heat-resistant aggregate, mixed with a heat-resistant cement, like Cement Fondu, is often referred to as castable, which is suitable for making pizza ovens and other outdoor ovens. The recommended mix of Firebrick Grog and Cement Fondu is 4 parts Grog to 1 part Cement.
