The mature development of the construction industry is a well-known phenomenon. Among the many construction sites, almost every stage requires massive amounts of concrete to assist construction. Among them, the quality of concrete is related to the foundation of the building. Its quality will directly affect the stability and risk of the building in the later period. But for concrete, segregation is a frequent bad phenomenon, and we need to use concrete anti-segregation agents to deal with it.
Everyone is talking about segregation, so what are the specific manifestations of concrete segregation? It means that the cohesion of the various components of concrete is insufficient, causing the mixture to separate from each other, causing the internal structural composition to be disordered. We only know that concrete anti-segregation agents must be added when mixing concrete, but we do not know what hazards will occur when concrete segregates.
1. It will affect the concrete pumping process, causing the mixer to stick to the tank and the pump tube to become clogged, thus delaying the progress of the project.
2. It will affect the appearance of the concrete after it is poured, resulting in sand patterns on the surface of the concrete and exposure of reinforced aggregates.
3. It will have a certain impact on the strength of concrete, resulting in a significant reduction in the pressure-bearing capacity of the concrete structure, a serious reduction in quality, and even rework.
4. It will affect the uniformity of the concrete, causing the shrinkage of each part of the concrete to be different, so after the pouring is completed, shrinkage cracks may occur. Especially when pouring floor slabs, segregation will thicken the cement slurry on the surface of the concrete, intensify shrinkage, and then lead to cracks and unnecessary rework costs.
5. It will have a serious impact on the durability properties of concrete such as frost resistance and impermeability.
Concrete segregation is a very bad phenomenon in construction projects. Its occurrence is often accompanied by various rework operations, during which a lot of unnecessary waste is wasted. cost input, and also delayed the normal project progress. Therefore, when mixing concrete, remember to add concrete anti-segregation agent.
