AASHTO T 155-2023 - Water Retention by Liquid Membrance-Forming Curing Compounds for Concrete

Introduction: Standard Name: Standard Method of Test for Water Retention by Liquid Membrane-Forming Curing Compounds for Concrete

Standard Number: AASHTO T 155-23

Scope: This test method covers the laboratory determination of the ability of liquid membrane-forming compounds for curing concrete to reduce moisture loss from mortar specimens during the early hardening period as a measure of their applicability for curing concrete. The values stated in SI units are to be regarded as the standard. This standard may involve hazardous materials, operations, and equipment. It does not address all safety concerns, and users must establish appropriate safety practices. Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns upon prolonged exposure. The quality of results depends on personnel competence and equipment calibration.
