2. Calcium aluminate cements - Wikipedia

   en.wikipedia.org/wiki/Calcium_aluminate_cements

   Concrete pipes for sewerage can be made either with full mass calcium aluminate cement concrete or with an internal liner of calcium aluminate cement mortar. Rehabilitation of man-accessible sewer infrastructures with 100% calcium aluminate mortar using one of the following placing methods: low pressure wet spray, spinning head wet spray, or ...

3. Refractory - Wikipedia

   en.wikipedia.org/wiki/Refractory

   Refractory materials are classified into three types based on fusion temperature (melting point). Normal refractories have a fusion temperature of 1580–1780 °C (e.g. fire clay) High refractories have a fusion temperature of 1780–2000 °C (e.g. chromite) Super refractories have a fusion temperature of > 2000 °C (e.g. zirconia)

4. Refractories heat-up - Wikipedia

   en.wikipedia.org/wiki/Refractories_heat-up

   Similarly to the Portland concrete used in civil engineering, water is added to the refractory castables to provide workability and allow molding, pumping, shotcreting or other forms of placement. Water exists within castables in free or combined forms: while free water remains in the pores without reaction with the materials' other ...

5. Vermiculite - Wikipedia

   Refractory/Insulation gunning and castable mixes [ edit ] Exfoliated vermiculite can be combined with high alumina (also known as calcium aluminate ) cements and other aggregates such as expanded shale , clay , and slate or sodium silicate to produce refractory/insulation concretes and mortars.

6. Calderys - Wikipedia

   In the first quarter of 2014, Calderys acquired Termorak Group in Finland, a company that specialises in refractory services including lining design, installation work and inspections. This acquisition enables Calderys to strengthen its position in the petrochemical and pulp and paper industries, as well as in the power business in Finland ...

7. Rotary kiln - Wikipedia

   en.wikipedia.org/wiki/Rotary_kiln

   The purpose of the refractory lining is to insulate the steel shell from the high temperatures inside the kiln, and to protect it from the corrosive properties of the process material. It may consist of refractory bricks or cast refractory concrete, or may be absent in zones of the kiln that are below approximately 250 °C (482 °F).
