Vacuum Dewatering of Concrete Improves Economic Benefits
Shorten the production cycle and improve work efficiency After vacuum casting, vacuum concrete dewatering reduces the water-cement ratio and solves the problem of difficulty in construction work and strength that ordinary concrete can not solve. This shortens the connection time between processes. And accelerate the construction cycle to create the conditions.
(1) After the construction of ordinary concrete, after the concrete is poured and molded, the time for plastering the surface needs to wait for 24 hours during the construction of the summer. However, the vacuum concrete is hard and fast and can be immediately wiped out after dehydration, which saves time and labor.
(2) Vacuum concrete can be removed in advance to increase the template turnover rate. Ordinary concrete construction (1520e) removes the mold for not less than 24 hours, and vacuum concrete can be removed in about 6 hours, and the template turnover rate increases by 25@%.
(3) Shorten the maintenance time. Due to its high early strength, vacuum concrete has a rapid increase in strength. It can shorten the maintenance time by 10% compared with ordinary concrete and can open traffic in advance. In the construction of Daqing Road, there was an intersection that opened to traffic 15 days after the concrete was molded. After observation, no changes occurred in the road section and there was no crack on the surface.
The economic benefits are achieved using concrete vacuum dewatering technology. The greatest benefit to the company is to save raw materials and reduce engineering costs. After the vacuum treatment of concrete, the strength is increased, the amount of cement is greatly reduced, and obvious economic benefits can be obtained. The template generally saves 15%-30%.
It can be proved through the above discussion that the vacuum dehydration process can not only improve the performance of concrete, but also obtain greater economic benefits and immeasurable social benefits. It is an effective and practical advanced construction technology, and it will continue to develop with the development of science and technology. , play a very active role in the basic construction.
