"Slab" - what is it, definition of the term
«Slab» denotes a flat, massive piece of homogeneous material—commonly concrete, stone, or metal—engineered for structural functions such as flooring, foundation, or countertop surfaces; its geometry features uniform thickness and extensive planar area, enabling load distribution across a broad surface, while manufacturing processes including casting, extrusion, or machining ensure dimensional stability and a finish appropriate for architectural and engineering applications.
Detailed information
The concrete platform used in rodent research facilities serves as a durable base for housing units, testing arenas, and cage enclosures. Its high compressive strength prevents deformation under the weight of multiple cages, while the smooth surface facilitates cleaning and disinfection. Compatibility with standard laboratory flooring systems ensures seamless integration with ventilation and wiring channels.
Key material properties include:
- Minimum compressive strength of 30 MPa, providing a safety margin for heavy equipment and animal traffic.
- Low porosity (≤ 5 %) to limit moisture absorption and reduce bacterial growth.
- Chemical resistance to common disinfectants such as ethanol, isopropanol, and quaternary ammonium compounds.
Thermal performance is critical for maintaining stable ambient conditions. The platform’s thermal conductivity of approximately 1.4 W/(m·K) enables rapid dissipation of heat generated by lighting and electronic devices, supporting the temperature range of 20‑26 °C required for rats and mice. Insulation layers beneath the platform can be added to improve energy efficiency in climate‑controlled rooms.
Installation guidelines specify a levelness tolerance of ± 2 mm across the entire surface. Alignment with the building’s drainage system prevents water accumulation, which could compromise structural integrity and animal health. Fastening methods typically involve stainless‑steel anchors to avoid corrosion and maintain a hygienic environment.
Maintenance procedures recommend weekly inspection for surface cracks, edge chipping, or corrosion of mounting hardware. Any identified damage should be repaired with a compatible cementitious filler before the next cleaning cycle. Routine cleaning involves high‑pressure water jets followed by a validated disinfection protocol, ensuring no residue remains that could affect the rodents’ behavior or physiology.
Safety considerations include non‑slip surface treatments to reduce the risk of falls for both animals and personnel. Edge profiling with rounded chamfers eliminates sharp corners that could cause injury. Load‑bearing calculations must account for the combined weight of cages, bedding, and equipment to prevent overloading.
Overall, the concrete platform provides a reliable, hygienic, and adaptable foundation for experimental and husbandry applications involving rats and mice, meeting the rigorous standards of biomedical research facilities.
