Recycling of secondary raw materials is a priority of waste handling in the countries of the European community. A potentially important secondary raw material is the product of the thermal transformation of cement-asbestos produced by prolonged annealing at sup o C. The product is chemically comparable to a Mg-rich clinker.

this material is limited to applications where the refractory is not subject to thermal cycling from high temperature (above 1000°C) to room temperature due to the devitrification process that occurs above 1000°C. By contrast materials that associate the benefits of mullite and amorphous phase to optimize the thermal shock resistance exist.
