Scope

Scope: This document specifies the raw materials, concrete performance, mix design, construction, and quality inspection of crack self-healing cement concrete. This document is applicable to non-structural stress cracks caused by changes in concrete temperature and humidity, with a width not exceeding 1.0 mm; Main technical content: The crack self-healing technology for cement concrete is an important direction in the development of modern concrete technology. Adding repair agents in advance during concrete preparation can endow concrete with crack self-healing capabilities, enabling active identification and automatic healing of cracks, which can greatly enhance the durability of concrete and reduce the cost of project operation and maintenance. This document specifies the raw materials, concrete performance, mix design, construction, and quality inspection of crack self-healing cement concrete, and is of great significance for improving the standardization and normalization of the application of repair agents in highway engineering.
