Research on Generating Mechanism and Treatment Measures of Concrete Bubbles

Abstract:

Concrete bubble is a common phenomenon in the concrete construction process. Generation and existence of concrete air bubble not only influence the concrete appearance, but also affects concrete service life. Especially for concrete surface with high requirements just as water diversion tunnel, concrete bubble gradually raises concern of engineering construction parties. Engineering technical personnel take a number of measures to eliminate concrete surface bubble in project practice. Based on analysis of many bubble elimination methods, generating mechanism and treatment measures of concrete bubble are discussed, providing reference for eliminating concrete bubbles.
