by At present, there are three commonly used cast structural materials, namely cast steel structure building, precast concrete building and cast wood structure building.
Although they are both cast structures, there are still great differences in their impact on the environment.
Want to know the differences between them? Follow Xiaobian and continue to look down! 01 cast wood structure cast wood structure cast wood structure because of its relatively low material price, its cost is also low.
Raw materials are lightweight building materials, which are easy to transport, have little impact on the surrounding environment during construction, and the recyclability of raw materials after demolition is also one of its advantages.
However, because the raw material is wood, the felling of trees will be increased, resulting in damage to the environment, which is contrary to the double carbon policy currently implemented by the state, and the quality of wood is low, and the application scenario will be relatively narrow.
In addition, due to the limited raw materials, precast wood structure buildings can only be limited and can not be vigorously promoted.
02 precast concrete building precast concrete building precast concrete components have improved in quality compared with wooden structures, but their heavy weight makes transportation a big difficulty.
Moreover, the raw materials of precast concrete components are still non recyclable building materials such as cement, sand and gravel, which will still produce a large amount of construction waste that is difficult to degrade after demolition, Increase the pressure on the environment.
03 cast steel structure from the main structure to the wall and roof structure, the cast steel structure steel structure building adopts recyclable or degradable materials, steel as the frame and thermal insulation wallboard as the enclosure structure, which can replace clay bricks, reduce the consumption of cement, sand, stone and lime, reduce the damage to non renewable resources, and echo the current national double carbon policy.
It not only has high resource utilization rate, but also can reduce the impact of construction waste on the environment and avoid the problem of “construction waste besieging the city”.
After reading the advantages and disadvantages of the above three common cast materials, Xiaobian just wanted to shout: “steel structure yyds!” Whether in terms of environmental protection or quality, steel structure has certain advantages, and cast steel structure also conforms to the current national double carbon policy.
It will be the core of the construction industry in the future! Keep up with the policy, do green building, Zhonghe is in action!!..
