Cement content of concrete

The cement content of concrete has an effect on its durability and permeability as well as having a direct relationship to the physical strength of concrete in a structure.  A lack of cement could lead to a more permeable concrete being present than specified, which would promote the ingress of carbon dioxide, chloride ion and/or moisture into the concrete, reducing the time taken for corrosion to form on reinforcing steel.

The cement content of concrete may be determined from dust or lump/core samples obtained from site, using either chemical testing methods or petrographic analysis (core sample recommended).

Results are expressed by the cement content found against mass of sample and are presented in tabular form.

The cement content is determined in accordance with BS 1881:Part 124:1988 and is covered by our *UKAS accreditation.
