What is the definition and specifications of fair-faced concrete?

Fair faced concrete is one which after removal of form work is not required to have any further finishes on it like plastering, etc.

Since concrete surface is intended to remain visible all relevant specifications of the concrete surface need to be given in the Tender.

Broadly speaking these specification besides giving compressive strength, etc. of the concrete should also be dealing with desired appearance of the concrete.

As in all works, they should also specify tolerance limits of defects or blemishes for fair faced concrete. Generally blemishes associated with Fair faced concrete are Blowholes, Steps, Fins, Colour variation, etc.

For details and better understanding you may refer to 'Guide to Off form concrete finishes' published by Cement Concrete and Aggregates Australia' Though in India we do not follow it I found it interesting and quite in detail.
