Concrete is defined as a composite material that consists essentially of a binding medium within which are embedded aggregates. Most of the time, it is a combination of fine aggregate and coarse aggregate.
Concrete admixtures improve the properties of concrete in construction with special requirements. Chemical admixtures such as concrete superplasticizers can provide a number of beneficial effects on the handling of consolidation of fresh concrete as well as on the performance of both hardened and fresh concrete. To be able to successfully achieve the desired results and in order to avoid unnecessary instances, there are some precautions to be taken into consideration.
Furthermore, chemical concrete admixtures are used to achieve the desired workability in case of a low water-cement ratio. These admixtures also help in setting time of concrete for long distance transportation.
The following are some of the most important purposes for which admixtures are used:
When Concrete Admixtures are being used?
Selection of Concrete Admixtures
Concrete chemical admixtures should be selected as per the specifications and should be used as recommended by a professional manufacturer like Corrotech Construction Chemicals.
For large concrete construction projects, the quantity of the admixture to be used should be obtained from tests reports for concrete mixed with admixtures at various percentage admixtures use. Chemical manufacturers say that these tests are conducted to fully understand the behavior of admixtures on the desired quality and strength of concrete. Thus, the optimum quantity of admixtures can be selected for a specific application based on results.
It is highly important that concrete admixtures should, including the Corromix Admixtures range, be used judiciously according to specification and method of application. This is to avoid adverse effect on concrete properties at fresh and hardened state.
