With the rapid development of the national economy, urban construction is changing with each passing day, and more and more high-rise buildings are being built. The underground space of high-rise buildings has also been valued as a parking space and warehouse for sale. Then, it is clear that the occurrence of concrete cracks greatly jeopardizes the use of underground space values.
The concrete cracks in the basement of high-rise buildings mainly have the following aspects: (1) the influence of cement hydration heat; (2) the influence of internal and external constraints; (3) the influence of external temperature changes; (4) the influence of concrete shrinkage deformation. Generally, such a bottom plate has a large area, and the base plate mostly doubles as a basement floor. After the foundation floor is poured, the internal maximum temperature differs greatly from the outside temperature. If certain measures are not taken, the concrete will be easily cracked, affecting the integrity of the structure and causing leakage of groundwater, causing extremely serious damage to the entire project.
Cracks that have been treated with unidirectional carbon fiber cloth
Due to the large cross-sectional size of the mass concrete structure, the possibility of cracks caused by external loads is small, but the temperature change caused by the hydration heat released by the cement during the hydration reaction and the concrete shrinkage will produce large temperature stress and shrinkage stress.
Once there is a problem with concrete cracks, Mankate unidirectional carbon fiber cloth can be used to strengthen the whole structure, which can effectively inhibit the further expansion of the crack and reduce the structural deflection. Nanjing Mankate's unidirectional carbon fiber cloth is made of imported carbon wire. It has high flatness, and the cutting is not scattered, it is the best quality. If you use it together with Nanjing Mankate adhesive, it can form a complete unidirectional carbon fiber cloth reinforcement system to further ensure project safety.
