Dyckerhoff anhydrite screed

Dyckerhoff screed is an anhydrite liquid mix manufactured in Dyckerhoff plants and delivered to construction sites as a ready-to-use product. The mix is applied with the use of an auger pump.

benefits of anhydrite screed

• very good heat conduction in a system with floor heating
• the bedding has a compact structure and low porosity - the mix wraps around each heating element, which facilitates heat dissipation to the room
• thanks to the high heat transmittance coefficient, the product improves heating efficiency
• low inertia of the bedding allows the use of economic heating programs and improves comfort of use

application

Dyckerhoff screed is a product designed for use inside buildings, particularly for floors with floor heating systems.

• used in dry rooms under various types of finish linings
• possible use in rooms with short-term high humidity
• not recommended for outdoor and indoor use with constant humidity

benefits of the solution

• the product is compliant with PN-EN 13813^* and it is marked with CE
• reduced thickness of concrete floor = reduced loading of ceilings (compared to cement screed)
• bedding does not require reinforcement due to the high mechanical strength
• no shrinkage during curing eliminates the problem of concrete floor cracking
• possible stepping on the bedding after 48 h
• continuation of finishing works in rooms after 5 days
• possible execution of large surfaces without joints
• short working time on the construction site

technical parameters

• compressive strength C20, C25, C30 [MPa]
• bending strength F4, F5, F6 [MPa]

• fluid consistency, self-leveling properties

thickness of bedding

Recommended minimum thickness of anhydrite bedding (construction of a single-family house):

• 50 mm for floor heating (min. 35 mm above 16 mm thick tubes)

• 35 mm for surfaces without floor heating
