ISO 3893:1977 PDF Download

ISO 3893:1977 is a standard that establishes a system of classification for concrete based on its characteristic compressive strength at 28 days. The standard applies to all types of concrete made using cements that comply with the general definition outlined in ISO/R 597.

The purpose of this standard is to provide a consistent framework for categorizing concrete based on its compressive strength, which is an important characteristic for assessing concrete quality and performance. By specifying the compressive strength at 28 days, the standard allows for comparisons and classification of different concrete mixes in terms of their strength properties.

In addition to providing a classification system, ISO 3893:1977 also includes a table that delineates specific requirements applicable to different categories of concrete. These requirements ensure that the concrete meets certain quality standards and performance criteria.
