Unlike normal concrete GRISU® is refractory. The material can withstand temperatures of over 1000°C and is suitable for processing in a build-up technique / modelling technique. With GRISU® refractory mortar you can easily build yourself a firebowl or a concrete kiln. Aside for the pizza oven in the garden, the mortar can be used for chimney repair, or the design of refractory moulds for metal and other fire-resistant objects.
For reinforcement, we recommend the use of our basalt fibres. When using the build-up technique you can use cement slurry as a contact bridge from our TERNAL® White refractory cement.
GRISU® is beige/brown and can be coloured with our pigments of the types 017 (green), 130 (red), 219 (white) and 502 (blue). The concrete solidifies in about 30 to 90 minutes depending on ambient temperature and hardens within 1 to 2 days. The processing time can be significantly shortened when using pigments.
