Admixtures & Additives - MC-Bauchemie
However, with the high-quality Centrilit additives from MC, you can significantly exceed the standard requirements specified for these types of concrete. Their pozzolanic properties strengthen the bond zone between the hardened cement paste and the aggregate, while optimising the packing density of the concrete structure down to the micro level.
Sika Plastocrete | Concrete Admixture | Sika Thailand
Sika Plastocrete is a plasticizer admixture for concrete and mortar in liquid form that acts both as a highly efficient plasticizer and waterproofing agent. Sika Plastocrete provides the following properties: Improved workability without increased water content. Allows easier compaction leading to denser concrete and superior finish.
Sikament NN | Superplasticizers
Sikament NN is a highly effective dual action liquid superplasticiser for the production of high slump concrete or as a substantial water reducing agent. Sikament NN provides the following properties: As a Superplasticizer: Workability is greatly improved Increased place ability in slender components with packed reinforcement

Powder Superplasticizers | Concrete Admixtures | Sika SA | Sika South
Construction Concrete Admixtures Powder Superplasticizers Sika provides a wide range of concrete admixtures with innovative options for concrete mix design, whether it's for substantially reducing the water content of a mix (e.g. with Sika ViscoCrete/ Sikament), using a more economical mix design or achieving sufficient early strength.
- How do plasticizers and water reducers affect concrete strength?
- Since the heat of hydration of mass concrete goes down when the cement weight goes down, plasticizers can do this. Plasticizers and water reducers are chemical admixtures used to make concrete more workable. Unless the mixture is “starved” of water, increasing the w/c ratio reduces the concrete’s strength.
- What are plasticizers & water reducers?
- Plasticizers and water reducers are chemical admixtures used to make concrete more workable. Unless the mixture is “starved” of water, increasing the w/c ratio reduces the concrete’s strength. An increase in durability is achieved by decreasing the water content (without “starving” the concrete).
- What is a hydrophilic plasticizer?
- The primary purpose of hydrophilic plasticizers is to improve the concrete’s plastic and flow properties, as evidenced by their increased wet ability. This plasticizer makes a lot of air get into the concrete mix. It is possible to lower the tension of the water in the solution and make the concrete more flexible.
- What is a plasticizer in concrete?
- and more resistant to cold. A plasticizer is an additive used in concrete to improve its workability, performance, and durability. Plasticizers are typically added to concrete mixes to make pouring, shaping, and finishing easier. They can also help to increase the strength and reduce the permeability of the hardened concrete.
- How do Plasticizers make concrete stronger and last longer?
- Plasticizers make concrete stronger and last longer by reducing the amount of water and cement needed to reach a certain level of workability. Since the heat of hydration of mass concrete goes down when the cement weight goes down, plasticizers can do this. Plasticizers and water reducers are chemical admixtures used to make concrete more workable.
- What makes a good plasticizer?
- A good plasticizer makes concrete or mortar flow in a way that is different from how an air-entraining agent does it. But some plasticizers also add air to the material, making it easier to work. A good plasticizer should add 1% to 2% of the air to concrete at most because adding air to concrete makes it less strong.
