Ceramics are usually understood to be products that are formed from inorganic, fine-grained raw materials with the addition of water, dried, and then sintered at over 900°C. Ceramics are characterized, among other things, by their impermeability, high mechanical strength, wear resistance, temperature resistance and corrosion resistance.

When we talk about cold-hardening ceramics, we are preferably talking about alkali-activated secondary raw materials. Activators such as alkali lyes and alkali water glasses can be used to produce binders that harden at temperatures < 100°C. These binders can be used for chemical curing. These binders can be used to produce chemically highly resistant and particularly abrasion-resistant mortars and concretes with ceramic properties. Due to their special properties, cold-curing ceramics are specially developed for areas of application that are exposed to very strong chemical and/or mechanical attack.
