Blinding concrete Sample Clauses
The 'Blinding concrete' clause specifies the use of a thin layer of low-strength concrete, known as blinding, placed over the prepared sub-base before the main structural concrete is poured. This layer serves to provide a clean, level, and stable surface, protecting the underlying material from contamination and preventing the loss of cement or water from the main concrete mix. By doing so, the clause ensures the quality and integrity of the structural concrete, reduces the risk of contamination, and facilitates accurate placement and finishing of the main concrete works.
