ISO 7033:1987 PDF Download

ISO 7033:1987 is a standard that outlines a specific method for determining the particle mass-per-volume and water absorption of fine and coarse aggregates used in concrete. The method utilizes a pyknometer, a device used to measure the volume of aggregate particles. The standard covers various aspects of the testing process, including definitions, required apparatus and equipment, sampling procedures, the actual testing procedure, relevant calculations, and guidelines for reporting the results.

By defining a standardized method, this standard ensures consistency and accuracy in the determination of particle mass-per-volume and water absorption of aggregates, which are crucial factors in the design and quality control of concrete. It provides a reliable and repeatable approach that can be followed by organizations and laboratories involved in the production, construction, or testing of concrete. Compliance with this standard helps to ensure that the aggregates used in concrete meet the required specifications and performance standards.
