Can the anchorage adhesive and sticky steel adhesive be replaced each other?
It is often heard that some people have asked whether the anchorage adhesive and sticky steel adhesive can be replaced each other during the reinforcement projects since they are both used to bond steel and concrete for reinforcement purposes. The answer is: No. Why? Let's know the reason together.
The difference between the anchorage adhesive and the sticky steel adhesive
The anchorage adhesive is used for planting rebars. It is suitable for the reinforced concrete structural members and the post-anchor design of structural reinforced ribbed steel bars. The main colloidal property is structural adhesive splitting tensile strength. While the sticky steel adhesive is used to bond steel. It is suitable for concrete bending, large eccentric compression and tension member reinforcement, and its colloidal performance is mainly based on tensile strength, elastic modulus. In terms of performance requirements, the anchorage adhesive is lower than the sticky steel adhesive.
In the reinforcement project, the anchorage adhesive and sticky steel adhesive must be specially used for different cases.
In the “Code for Acceptance of Construction Quality of Reinforced Building Structures” GB50550-2010, it is stipulated that during the process of reinforcement, anchorage adhesive and sticky steel adhesive are strictly prohibited together. Because the price of barreled anchorage adhesive is only 70-75% of the price of sticky steel adhesive. If the sticky steel glue manufacturer directly uses the formula of the barrel anchorage adhesive to replace the formula of the sticky steel glue in order to save the cost, the adhesive property of the sticky steel adhesive which does not meet the production standard will be reduced, and it will leave security risks for the reinforcement project. Therefore, when doing reinforcement work, we must choose a reliable manufacturer of sticky steel glue.
