BS 1881-122:2011

Testing concrete. Method for determination of water absorption

Status : Confirmed, Current   Published : July 2011



What is this standard about?

It provides a way to test the water absorption of concrete.

Who is this standard for?

  • Manufacturers and users of concrete
  • Designers, engineers, architects
  • Regulatory bodies

Why should you use this standard?

It specifies a method for determining the water absorption of concrete specimens cored from a structure or a precast component.

The method may also be used to determine the water absorption of concrete cast into prisms or cylinders where the surface to volume ratio can be calculated and where no point in the specimen is more than 50 mm from a free surface.

The measured water absorption of the specimen is corrected to that equivalent to a surface to volume ratio of a core 75 mm long with a diameter of 75 mm.

NOTE: Absorption values for cast specimens are normally slightly lower than those for a core from the same concrete but the difference can be more significant if the aggregate is absorbent.

What’s changed since the last update?

This part of BS 1881 is a technical revision superseding BS 1881-122:1983 which is withdrawn.
