Abstract

The present invention discloses a water-proof rust-resistant agent with the ingredients by the following weight percent: 10 to 20 percent of modified organosilicone, 10 to 30 percent of alkamine, and 60 to 70 percent of water. The modified organosilicone is alkyl alkaoxy silane with the chemical formula of R'Si(OR3)3, wherein, R' and R represent the alkyl. The present invention is free from negative influence on the condensation time and the strength of the concrete, and has the advantages of low consumption volume and high rust-resistant performance. The present invention has remarkable functions on the self water prevention of the concrete structure and the rusty corrosion of the steel bar, and also has the functions such as water reduction, air introduction, plasticity preservation and corrosion prevention, thereby can be used as the additive for the concrete pumping agent, the water-proof agent and the rust-resistant agent.

Description

(1) Technical field [0001] The invention relates to a reinforced concrete rust inhibitor. (2) Background technology [0002] According to the survey on the durability of my country's coastal port wharf projects, the durability problems caused by the corrosion of steel bars account for more than 80% of reinforced concrete, and many marine engineering buildings have rust cracks along the bars and concrete in only 3 to 5 years after construction. The peeling of the protective layer and other phenomena have to be overhauled in advance, and the durability of the port project is far less than the designed service life. Therefore, effective measures must be taken to improve the durability of reinforced concrete in harbor engineering construction. [0003] In the United States, the United Kingdom, and the Middle East, there are a large number of reports on the concrete structure damage of roads and bridges caused by deicing salt and seawater erosion. Corrosion of steel bars is also...
