PRODUCT DATA SHEET
BSB-CT maxifirm-lux
Hardened concrete ground
Basics of ground concrete surfaces Compared to conventional screeds designed as a carrier layer for floor coverings, ground concrete surfaces have some relevant differentiating features. One is the fact that the surfaces are exposed to stresses directly from the time of installation or grinding. Untreated, the component is characterized by high open porosity, it absorbs liquids quickly. Even surfaces polished to a high gloss retain their absorbency. They appear dense to the observer, but the microporosity remains. Damage or other influences that cause a change in the surface cannot be repaired without affecting the aesthetics of the floors. Ground concrete surfaces are one of the few visible components that are created on site from scratch, i.e., in the project. It goes without saying that each floor is unique. Its technical and aesthetic properties vary depending on the type and origin of the aggregates, the recipes, the professionalism of the processors, or the weather conditions during installation. Installing and grinding concrete surfaces requires not only very precise planning and work down to the last detail but also appropriate conditions during and after installation and grinding. For example, it is very important to maintain appropriate drying conditions. Drying should be as uniform as possible. The surfaces must not be covered too early and only with special, diffusion-open materials. The surfaces of BSB-CT maxifirm-lux hardened concrete ground can be treated in various ways. On the one hand, there is the option of impregnating with stone oil, which is used either colorless or with the addition of pigments. Alternatively, the absorbency of the surfaces can be reduced by treatment with pore fillers based on acrylic. Furthermore, there is the possibility to hydrophobize the surfaces. Hydrophobizations prevent the penetration of liquids into the covering. They are usually colorless and allow easier maintenance cleaning. BSB-CT maxifirm-lux hardened concrete ground always shows color differences, which belong to the character of this type of surface. Those who have chosen such a covering must, unlike conventional screeds, expect an additional construction time of about 4-6 weeks. BSB-CT maxifirm-lux hardened concrete ground is not unrestrictedly usable. Therefore, consult specialists already in the planning phase. BSB-CT maxifirm-lux hardened concrete ground consists of the binder cement, aggregate, water, concrete additives, and possibly pigments. It complies with the standards according to SIA 567 252 (floor coverings made of cement, magnesia, synthetic resin, and bitumen) and is suitable for indoor and outdoor use. By adding steel fibers, the technical values of BSB-CT maxifirm-lux hardened concrete ground can be positively influenced. Properties

BSB-CT maxifirm-lux hardened concrete ground can be used both indoors and outdoors. With their own character, especially due to the noble appearance of the high-gloss polishes, these coverings are part of contemporary modern architecture. But not only that, because due to the terrazzo look, coverings made of BSB-CT maxifirm-lux hardened concrete ground are excellently suited for the renovation of old buildings. BSB-CT maxifirm-lux hardened concrete ground is installed as a visible covering in composite and can be exposed to high loads. Additives
The technical properties of BSB-CT maxifirm-lux hardened concrete ground can be influenced in various ways. By dosing the cement content and adding concrete additives, both drying and technical values such as tensile adhesion and compressive strength can be influenced. Also, by mixing in steel fibers, various technical values can be improved. High strengths
In the hardened state, usually after 28 days, BSB-CT maxifirm-lux hardened concrete ground has high strength. They have high resistance to various liquids such as alkalis or benzols, etc. Notes
BSB-CT maxifirm-lux hardened concrete ground must be protected from too rapid drying. They must not be exposed to drafts in the first 21 days after installation. BSB-CT maxifirm-lux hardened concrete ground can also be colored with appropriate pigments. These are facts that make them extremely attractive for object construction. It is recommended to treat the surfaces of BSB-CT maxifirm-lux hardened concrete ground with impregnations or sealants. This guarantees a long-term unchanged surface and facilitates maintenance cleaning. Care for the surfaces according to the care instructions and only with the products recommended there.
Attention: High-gloss polishes are never acid-resistant. Biollay Spezialbau AG - a company of the FS Group Version 2/2019
