What construction projects to pay attention to winter additive
Time:2015/11/3 16:56:34                  Click:1503

With the increasing use of concrete admixtures, more and more sites will use concrete admixtures, there are more sites will use concrete admixture double admixing technology to improve the performance of concrete to improve concrete's mechanical index and durability reduce the construction period, save cement.

During the winter construction, if a good mix concrete directly frozen in the air, then the role of cement basically stopped, the intensity does not increase, it will affect the life and safety of future construction, etc., so in the winter, when construction, In order to maintain the normal use of the strength of concrete, it is necessary to accelerate concrete setting before digestion cement, the concrete from freezing, concrete admixtures generally in the winter will be used include air-entraining admixture, early strength admixture and antifreeze Three admixtures.

Three additives generally used in combination, the performance of concrete will play better, and the project is completed degree will naturally speed up.

Winter highway construction project, for example, typically will be used in admixture of cement concrete pavement, curbs, gutters and other surface structures and crash barrier structure, once in a while Weihai highway construction, because tight schedule, so must the winter construction, construction of more thin-walled structures, in order to ensure the quality of concrete in construction on the application of air entraining water reducing agent, increase the workability of concrete to meet construction standards in winter, after the construction of the highway quality inspection results It showed strength fully meet the design requirements.
It can be seen, when the winter construction of concrete, to use air-entraining superplasticizer increase the workability of concrete, add another accelerator and antifreeze.
