sand-lime brick
Technical/Low FrequencyTechnical/Formal
Definition
Meaning
A type of building brick manufactured from sand and lime, hardened by chemical reaction under steam pressure, rather than by firing in a kiln.
A durable, pale-coloured masonry unit known for its precise dimensions and smooth surface, primarily used in structural walls and facing.
Linguistics
Semantic Notes
It is a specific type of calcium silicate brick, distinct from traditional clay bricks. The term is a compound noun where the hyphen is sometimes omitted ('sand lime brick'), especially in American usage.
Dialectal Variation
British vs American Usage
Differences
Both varieties use the term. British English may be more likely to retain the hyphen. The term is highly specialised in both regions.
Connotations
Technical, industrial construction material; connotes modernity and precision compared to traditional fired clay bricks.
Frequency
Equally low frequency in both dialects, confined to architecture, construction, and civil engineering contexts.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation that results in 'песчано-известковый кирпич' without confirming the specific technical product. The Russian term 'силикатный кирпич' (silicate brick) is the direct equivalent.
Common Mistakes
- Misspelling as 'sand-lime-brick' (with two hyphens) or 'sand lime-brick'. Incorrectly calling it a 'cement brick'.

FAQ
Frequently Asked Questions
No. Concrete bricks use cement as a binder, while sand-lime bricks use lime. They are different chemical processes and material families.
Generally not recommended for below-ground or damp environments unless specifically designed and certified for such use, as prolonged moisture can degrade it.
Key advantages include high compressive strength, excellent fire resistance, good sound insulation, consistent size and shape, and a clean, light appearance.
It is made by mixing sand, lime, and water, then pressing the mixture into moulds. The bricks are hardened not by firing, but by autoclaving (curing with high-pressure steam), which causes a chemical reaction forming calcium silicate hydrates.
