FAQs
What does BBA certified mean for these blocks?
BBA certification signifies that the product has undergone rigorous assessment by the British Board of Agrément, confirming its fitness for purpose, quality, and compliance with relevant standards.
Can these blocks be used below ground level?
Yes, the H+H Standard Celcon Blocks are suitable for use in foundations and below damp-proof course (DPC) level, provided they are used in accordance with relevant building regulations and structural design.
What is the density of the H+H Standard Celcon Block?
The density of the Standard Grade Celcon Block is approximately 600kg/m³.
What is the compressive strength?
The compressive strength of the Standard Grade Celcon Block is 3.6 N/mm².
Can I use these blocks for load-bearing external walls?
Yes, they are suitable for use as the external leaf of cavity walls and solid walls, offering reliable structural support when laid correctly.
What are the dimensions of this block?
The dimensions of the H+H Standard Celcon Block are 440mm (length) x 215mm (height) x 140mm (width).
How do I clean the blocks if they get dirty before use?
It is best to avoid significant soiling. If minor dirt is present, brush it off. For heavier soiling, a damp cloth may be used, but ensure the blocks are fully dry before laying.
Troubleshooting
Block cracking during handling or laying
Ensure blocks are stored correctly and handled with care. Verify that the mortar bed is level and consistent to prevent uneven stress. Avoid dropping blocks from height.
Mortar adhesion issues
Ensure block surfaces are clean and free from dust or debris before applying mortar. Check that the mortar mix is appropriate and has been applied correctly according to manufacturer guidelines.
Achieving required thermal performance
While the blocks offer moderate thermal performance, consider adding appropriate insulation layers to the wall construction if higher thermal resistance is required by building regulations or project specifications.
Pros and Cons
Pros
- Versatile application across multiple building elements.
- BBA certification assures quality and compliance.
- Consistent performance simplifies construction planning.
- Reliable compressive strength for structural applications.
- Standardized dimensions ensure ease of use and integration.
Cons
- Density of 600kg/m³ may be heavier than some alternative materials for manual handling.
- Thermal conductivity of 0.15W/mK is moderate; may require additional insulation in certain climates.
- Specific compressive strength (3.6N/mm²) may not be suitable for all high-load bearing applications without engineering assessment.
Setup, Compatibility & Care
Setup: H+H Standard Celcon Blocks are designed for standard masonry construction. They are typically laid using mortar in accordance with established building practices. Ensure a clean, level base is prepared for foundations and wall construction.
Compatibility: These blocks are compatible with most standard building materials, including concrete, brick, timber, and steel when used in appropriate structural assemblies. They are suitable for use with various mortar types and DPC solutions. Always consult relevant building codes and structural engineer specifications for complex applications.
Care: Store blocks on a level surface, off the ground, and away from prolonged exposure to standing water. Protect from extreme weather conditions during storage and transit. Handle blocks with care to avoid unnecessary damage.
