T/HCBA 002-2022 High-performance concrete spraying application technical specification
Abstract
Main technical content: The main aspects of quality control for high-performance shotcrete are clarified. Since the quality of high-performance shotcrete is influenced by multiple factors such as raw materials, mix ratio, spraying process, spraying equipment, and construction operators, this specification stipulates the requirements for each aspect involved in its production and application. The spraying process of shotcrete is divided into wet spraying and dry spraying. Dry spraying has a high rebound rate and serious pollution, and the construction technology level of dry spraying shotcrete in China is relatively low. This specification only includes high-performance shotcrete when using the wet spraying method.
