bs test for chloride content in concrete

Concrete Chloride Testing Structural Guide

Testing of Chloride Content. The testing of the chloride content of reinforced concrete is done as stipulated in BS1881. When the structures are retrofitted, this issue is the rise and the requirement of the testing of chloride becomes a must with the exposure condition that the structure is located.

Chloride in concrete (BS 8500)

Chloride in concrete (BS 8500) BS 8500 Concrete Complementary British Standard to BS EN 206 requires that concrete should have a maximum chloride ion content by mass of cement depending on certain criteria. This is expressed as a chloride class e.g. Cl 0,40 The use of a comma,instead of a full stop . is how it is expressed in the main Standard BS EN 206.

Chloride limits in the ACI 318 Concrete Construction

A new test, the Soxhlet method (ACI 222.1), has been de-veloped to test these aggregates or to test concrete made with these aggregates. This test uses chunks of concrete or aggregate instead of crushed and powdered material. The chunks or pieces are treated with boiling water, which is then tested for chloride content. So far, the test appears
