ISO 1920-4:2020 PDF Download

ISO 1920-4:2020 is a standard that provides guidelines and procedures for testing the strength of hardened concrete. The standard aims to ensure consistent and accurate measurement of the strength properties of concrete samples. It outlines the various test methods and techniques that can be employed to determine the compressive strength of concrete.

The standard covers procedures for preparing concrete test specimens, including the size and shape of the specimens, as well as the curing conditions required for proper hardening. It also describes the testing apparatus and equipment that should be used, including the compression testing machines and load cells.

ISO 1920-4:2020 provides detailed instructions on conducting the compression test, which involves applying a steadily increasing load to the concrete specimen until it fractures. It defines the calculation methods for determining the compressive strength based on the maximum load applied and the dimensions of the specimen.
