The fluidity of concrete is one of the main important characteristics of the material, because its plasticity directly affects its ability to be easily placed in a form or formwork without loss of strength and quality. Increasing the flow of concrete can be useful in some construction situations where it is necessary to make it easier to place or to provide easier access to hard-to-reach places. In this article, we will give examples of some methods for increasing the fluidity of concrete.
Increasing the volume of water when mixing the material
Adding more water can increase the flow of concrete. This is the simplest method, which is usually used by either inexperienced or simply irresponsible craftsmen. After all, this approach can adversely affect the strength and durability of the entire concrete structure. Therefore, it is important to maintain the correct ratio of water and cement to ensure optimal strength.
Use of plasticizers
Plasticizers are chemical additives that are added to concrete to reduce its water absorption and increase plasticity. They increase the fluidity of concrete without the need to increase the amount of water.
Use of superplasticizers
Superplasticizers are the same plasticizers that allow you to increase the fluidity of concrete at very low water acceptability, but have been more modernized. They are most effective when it is necessary to obtain a more fluid consistency of concrete, and in addition, high-quality superplasticizers, such as Teknoflow Super, ensure uniform distribution of the material during pouring without the formation of voids and increase the strength characteristics of the concrete structure, even at low temperatures.
Use of special aggregates
The use of some special aggregates, such as reclamation sand or high-quality fine-grained aggregate, can improve the flow of concrete.
Of course, it is better to use special additives for concrete, which do not impair its quality in any way. And in order to choose the right material, please contact 067 486 42 41 for advice.
