What is construction adhesive

This application is a new application field of building structural adhesive. Although the bonding and assembly of the concrete roof of Sydney Opera House in Australia and the examples of column lengthening and foundation pile lengthening in China earlier, because the basic research on its design theory and calculation is still in the initial stage, it is still in the trial period. However, its development prospects should be very broad.

Building structural adhesive can be used not only for pouring and bonding between steel plate and concrete when steel clad reinforcement of concrete structure, but also for sealing cracks in general components. This kind of application is also a large and wide field. It can be used not only in building components, but also in the repair and repair of various engineering projects such as water conservancy and military industry.

Building structural adhesive can be used to bond and repair all kinds of old buildings and ancient buildings (wood structure, masonry structure and concrete structure), as well as a unit component. The repair process is simple and the repair effect is good. There are many examples of such applications. In addition, it has been used in the repair of highway pavement and airport runway for decades. For the bonding and repair of hydraulic structures, building structural adhesive also has broad application prospects.

This kind of application mainly uses the building structure adhesive as a bonding material to firmly bond the steel plate or profile used for reinforcement, or other reinforcement materials (such as carbon fiber, aramid, chlorine fiber, etc.) to various concrete components, such as beams, columns, joints, brackets, slab surfaces, tunnels and arch roofs, so as to strengthen the original concrete structure. There are many application examples of building structural adhesives in this field, which have been completed; The reinforcement works of concrete structures have achieved satisfactory results.
