BS 1881-128:1997 PDF Download

BS 1881-128:1997 is a standard that focuses on the testing and analysis of fresh concrete. Specifically, it describes three different methods for determining the total cement content present in the concrete samples. These methods provide a means for accurately assessing the cement content, which is an important parameter in evaluating the quality and properties of concrete.

In addition to determining the cement content, two of the tests described in the standard also allow for the determination of the proportions of pfa (pulverized fuel ash) or ggbs (ground granulated blast-furnace slag) present in the concrete. This feature adds value to the standard by enabling the analysis of supplementary cementitious materials used in concrete mixtures, which can have a significant impact on its performance and durability.

By providing clear instructions and guidelines for these analysis methods, BS 1881-128:1997 ensures that laboratories and testing facilities have a standardized approach for assessing the cement content and optional supplementary materials in fresh concrete. This standard serves as a valuable resource for quality control and assurance in the construction industry, enabling professionals to make informed decisions regarding the use of specific concrete mixtures.
