ActiveTechnical requirements of anti-washout admixture for underwater concrete
水下不分散混凝土絮凝剂技术要求
Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and packaging for anti-washout admixtures used in underwater concrete. It is applied in construction projects involving underwater concreting, such as bridge foundations, port facilities, and dam repairs, where the admixture prevents cement washout and ensures concrete cohesion during placement in water. The standard serves as a quality benchmark for manufacturers and testing laboratories to evaluate the performance of these admixtures in marine or hydraulic engineering contexts.
