ISO 4111:1979 PDF Download

The ISO 4111:1979 standard outlines a method for determining the consistency of fresh concrete by assessing its degree of compactibility. The aim of this standard is to provide a reliable and standardized approach to evaluating the workability of concrete. The method described in the standard can be applied to concrete of various consistencies, with the exception of very fluid concrete. However, it is important to note that this standard is not applicable to concrete that contains aggregates larger than 40 mm in size. By employing the guidelines outlined in this standard, professionals can better understand and control the workability of fresh concrete, thus ensuring the quality and performance of the final product.
