Reinforced concrete should be the architectural term that is often heard. As the name implies, reinforced concrete is composed of two materials with different mechanical properties, such as steel and concrete. The tensile and compressive properties of the steel bars are good, especially the tensile properties are good. The concrete has good compressive performance and poor tensile strength, and the compressive strength of concrete is about 10 times of the tensile strength. Take the example of the beam, under the load, the upper part of the neutral layer of the beam is the compression zone, and the part below the neutral layer is the tension zone.
Then, why does reinforced concrete that looks so strong have such a serious problem of cracking or even collapse? In fact, the reason is still very complicated. Due to the low tensile strength of the concrete, the plain concrete beam will be broken by the crack in the tension zone under the small load. At this time, the compressive strength of the concrete in the compression zone is not fully utilized. Since the tensile properties of the steel are good, if a proper amount of steel is placed at the lower edge of the tension zone of the beam, the steel is used instead of the concrete, so that the compressive strength of the compressed concrete can be fully utilized, which greatly improves the bearing capacity of the beam. If the width of small cracks is above 0.1mm and they are still at rest, they can be directly used by surface sealing. Here, Nanjing Mankate sealing glue is recommended. Mankate sealing glue has high tentacity, strong adhesion, abrasion resistance and corrosion resistance. It is suitable for this simple gap repair.
Reinforced concrete beams are not a simple combination of two materials, steel and concrete. To make these two materials with different mechanical properties work together as a unified component, the basic premise is to ensure the bond between them. It is not only limited to the adhesion of the hydrogel to the surface of the steel bar, but it contains the combined action, that is, the friction and the adhesion of the surface of the steel bar or the mechanical nip between the surface ribs and the surrounding concrete. These bonding effects allow the steel and concrete materials to work together. Bonded steel reinforcement is made of special sticky steel plate reinforced adhesive as the binder, and the steel plate is pasted on the surface of reinforced concrete structure, wood structure and masonry structure, and the strength of the original structure is strengthened by the performance of the reinforced adhesive. It is equal to double insurance.
Mankate's bonded steel plate reinforced adhesive has no added quartz stone, light weight, no sag on the back surface, excellent anti-aging, chemical corrosion resistance and water resistance; small shrinkage after curing, large ratio range and long operation time; if you are interested in this product, please call our one-stop service hotline: 400-894-5118.
