AASHTO T 155-13 (2017) PDF Download

The AASHTO T 155-13 (2017) standard outlines a laboratory procedure used to evaluate the effectiveness of liquid membrane-forming compounds in curing concrete. This standard focuses on measuring the compounds' ability to reduce moisture loss during the initial stage of concrete hardening.

The test method described in this standard is designed to assess the efficiency of the curing compounds by quantifying their capacity to retain water within the concrete. It serves as a vital tool for manufacturers and users of these compounds to evaluate their performance and ensure compliance with quality standards.

The standard provides clear instructions on the laboratory procedure to be followed, specifying the necessary materials and equipment required for conducting the test. Test specimens are prepared using a specific concrete mix, and the liquid membrane-forming curing compound is applied according to the manufacturer's recommendations.

The efficiency of the curing compound is determined by analyzing the moisture loss from the concrete specimens during the early hardening period. This measurement allows for a reliable assessment of the compound's ability to retain water and facilitate proper concrete curing. Compliance with this standard ensures the effective use of liquid membrane-forming curing compounds in concrete construction, promoting optimal concrete performance and durability.
