AS 1012.25.1:2020 standard provides a detailed procedure for testing the fibre content of concrete in its plastic state using a wash-out method. The purpose of this standard is to establish a uniform method for determining the amount of fibres in concrete samples.

The test involves taking a sample from a concrete mixture, either from a concrete load or from laboratory-prepared concrete that has been compacted into a known volume. The sample is then subjected to a wash-out process where the steel or synthetic fibres are carefully removed, separated, and dried.

The fibre content is determined by measuring the mass of the fibres collected and the volume of the concrete sample. This standard ensures that consistent and accurate measurements of fibre content can be obtained, which is important for assessing the quality and performance of fibre-reinforced concrete. It provides a reliable and standardized method for testing the fibre content, thereby helping to ensure the integrity and reliability of concrete structures.
