The prepared sample is then analysed in the CM measurement device to determine the moisture level. High-quality flowing screed compound on an alpha hemihydrate basis for manufacturing calcium sulphate flowing screed for truck mixers and as factory-mixed dry mortar.
When subjected to moisture, Ettringite, a salt that damages the building substance can be formed. Excellent surface properties ansftzgips uniform quality. The cold dry air is subsequently diverted to the heater section and heated up. Calcium sulphate flowing screed is delivered to the building site as a pre-mixed dry mortar in silo systems or bags, with mobile trans-mix vehicles or as ready-mixed self levelling floor screed in a truck mixer.
With cementitious screed the binder is cement; for calcium sulphate flowing screed the binder is calcium sulphate.
Alpha hemihydrate in ansetzgisp autoclave, or beta hemihydrate in the boiler plant or in the revolving kiln. Find out more about additional ansftzgips. Alpha gypsum CAB 30 Classification acc.
With electrical underfloor heating, there is generally a danger of overheating when the screed is covered by an insulating material — such as a cabinet not mounted kjauf — and when the floor thermostat is not located directly underneath it.
No heating until dry Should you apply electrical underfloor heating on a still new flowing screed, it is vital to ensure that the screed has achieved the required readiness to accept a floor covering before applying the floor covering, as it cannot be heated until dry like normal heated screed. Find out more about additional gypsums.
Ventilation also plays a decisive role here.

Technical advice Our experts from Knauf answer your questions. Find out more about additional gypsums Material Science Get to know gypsum the building material. The optimum approach is by technical heating, e. Mein Merkzettel Gesamten Merkzettel ansehen. Die stone Type 4 gypsum is used for high quality prosthodontics. Flowing screed compound on an alpha hemihydrate basis for manufacturing calcium sulphate flowing screed as factory-mixed dry mortar.
Always in use K Sentials Binders for perfect results. For a heated screed the drying process can be accelerated by heating up the screed. When the screed is installed without joints, it is the ideal substrate for laying large format and diagonally laid tiles or natural stone coverings.
CF5 Download product data sheet. From a chemical standpoint, gypsum is calcium sulphate and can be expressed with the formula CaSO 4 x 2H 2 O. Furthermore, it is used in plastic prosthodontics and for preparing repair model castings. On the other hand, conventional screed is subject to deformation when drying. It differentiates between 5 types:. Die stone In contrast to type 4 die stone, type 5 die stone has a high expansion capability.
By selecting suitable aggregates and adequate quantities of water, calcium sulphate screed can be manufactured in different strength classes. Flowing screed can be heated up after just 4 to 7 days after installation so that the screed dries even faster.

Fragen zu Trockenbau- und Boden-Systemen Tel.: Flowing screed binders Certified quality. Find out more about flowing screed binders. Flowing screed can be applied across the entire living space including kitchens and bathrooms.
Binders for mobile mix-systems for flexible deployment on the building site: It is a simple, wet cleaning procedure utilizing natural limestone resulting in an end product of moist, fine desulphurized flue gas gypsum that is delivered directly as a raw material to the economic cycle of the building materials industry.
Both the technology for desulphurization as well as the development for the application of FGD gypsum in the building materials industry is based on our research and development work and our comprehensive know-how as well as close cooperation with the operators of power plants.
Knauf – Flowing screed binders
Flowing screed compound on an alpha hemihydrate basis for manufacturing calcium flowing screed with mobile trans-mix vehicle and as factory-mixed dry mortar. Moulding gypsums are products made of calcium sulphate hemihydrate with optional factory additives, where very pure brilliant raw gypsum is used in their manufacture.
The CE-marking provides the basis for knnauf marking of products within the EU and may only be used by the manufacturer if a declaration of performance is available. When not discontinued by expansion joints, the planning is simplified saving time and money for the investor, which in turn provides a more visually appealing room image. Perimeter joints prevent the formation of cracks. For saw-cut models, models for model casting, in the fields of implantology, master models for the crown and bridge, inlay and onlay techniques.
It is easy to use and is characterized by its smooth surface, a relatively high expansion and a low compressive strength. Hier erfahren Sie mehr. Gypsum ansetzglps formed between and million years ago. It is not necessary to additionally sand off the surface, if installed according to the application regulations. Only for larger or geometrically complex surfaces and with heated screed is it necessary to install structural joints and movement joints. Yes, on flowing screed all conventional floor coverings such as tiles and natural stone, carpet, PVC, linoleum, parquet, laminate or resin screed flooring can be used.
A combination of both is ideal. Should you apply electrical underfloor heating ansetzgipx a still new flowing screed, it is vital to ensure that the screed has achieved the required readiness to accept a floor covering before applying the floor covering, as it cannot be heated until dry like normal heated screed.
Always close at hand – continually available. Additional Gypsums Production, use, product information – all about thermal and natural anhydrite. Can I use flowing screed for cooling as a cooled floor?
