ASTM C936/C936M-21b PDF Download

The ASTM C936/C936M-21b standard provides guidelines and requirements for interlocking concrete pavers used in the construction of paved surfaces. The specification covers the materials used in manufacturing the pavers, including cementitious materials, aggregates, chemical admixtures, and integral water repellents.

The standard also outlines physical requirements for the pavers, such as compressive strength, dimensional tolerances, and surface quality. It provides guidance on sampling and testing procedures to ensure that the pavers meet the specified requirements.

Additionally, the specification includes guidelines for visual inspection of the pavers during the construction process and sets criteria for rejecting specimens that do not meet the required standards.

Note 1 of the specification emphasizes that if specific features are desired, such as weight classification, higher compressive strength, surface textures, finish, color, or other special features, these properties should be specified by the purchaser. The specification advises consulting with local sellers to determine the availability of units with the desired features.
