In the first quarter of 2023, shortages of cement materials remain in many regions of the country, and companies producing ready-mixed concrete continue to be unable to fulfill all of their orders or are forced to postpone certain jobs due to the inability to obtain the cement necessary to meet the design specifications of concrete . This is especially true for high-strength concrete mixtures. Without a real solution to this logistical problem, many in the industry are trying to find alternative solutions for mixtures that require large volumes of cement. Fortunately, the answer has already been found – in the form of superplasticizers.
Superplasticizers are traditionally known for their water-reducing properties, which improve the flow of concrete without adding additional water and reducing the overall strength of the mixture. These same qualities make it possible to reduce the amount of cement materials.
When mixed with water, cement particles naturally attract each other and form clumps. This means that only some cement particles can properly complete the hydration process, reducing the strength of the finished product. High-strength mixtures require more cement to increase the percentage of cement that binds and hydrates with water molecules. When a superplasticizer is present in the mixture, it bonds with the cement particles and neutralizes the force that pulls them together. This prevents them from forming clumps in the mixture and frees up more cement molecules to complete the hydration process. This way you get the same result, but with less cement than using a traditional high-strength mixture.
When choosing a superplasticizer for a concrete mixture, many different factors must be taken into account. Flow and strength requirements must be taken into account, as well as weather conditions and the area of application.
