Abstract

The concrete structures of mud concrete road and bridge road engineering generally faces serious freezing and thawing damage due to small section, large contact area, and the double role of vehicle load and bad natural environment, as well as the salt used to melt snow in winter. In order to improve the overall level of concrete frost resistance evaluation and concrete frost resistance design of our country's road engineering, through testing system, this paper also studies the influence law to hardened concrete bubble characteristic parameters of gas amount, air-entraining agent varieties, water cement ratio and other factors, which provides reference for concrete frost resistance design, air-entraining agent quality evaluation and the establishment of the relevant specifications. In addition, this papers uses high frequency vibrating rod in the laboratory to simulate high frequency vibrating concrete construction on site and studies the influence of high frequency vibrating to frost resistance of concrete by the influence rules of the time of vibrating to hardened concrete bubble characteristic parameters.
