Testing concrete -- Procedure and terminology for the petrographic examination of hardened concrete
This British Standard describes procedures and terminology for the examination of hardened concrete and mortar. The procedures are intended to be performed by an appropriately qualified or experienced concrete petrographer.
The principal application of the method described requires the use of a polarizing petrological microscope for the examination of concretes containing Portland and other cements. The petrographic procedures outlined are applicable to the examination of samples of all types of hardened hydraulic cement-based materials, including concrete, mortar, grout, cement and gypsum-based plaster, render, terrazzo, and similar materials.
In this British Standard, the material for examination is designated as “concrete”, even though the commentary is also applicable to the other mixtures, unless the reference specifically excludes a material other than concrete.
