Admixtures for Concrete & Ancillary Products | Mapei
MAPEI’s Admixtures for Concrete products are formulated with an emphasis on high-performance concrete. By incorporating the optimum use of Portland cement and cementitious material in combination with local aggregate, our products achieve superior strength, workability and enhanced finishing at low water-to-cement ratios.
MasterGlenium 3030 | Master Builders Solutions - North America
Recommended uses of MasterGlenium 3030 concrete superplasticizer: Concrete where high flowability, high-early and ultimate strengths and increased durability are needed Self-consolidating concrete Concrete where normal, mid-range, or high-range water-reduction is desired Concrete where normal setting times are required
Use of Water Reducers, Retarders, and Superplasticizer
Water reducers, retarders, and superplasticizers are admixtures for concrete, which are added in order to reduce the water content in a mixture or to slow the setting rate of the concrete while retaining the flowing properties of a concrete mixture.
Superplasticizer: Types, Advantages & Disadvantages
Superplasticizers (SPs) are also known as high- range water reducers that are additive used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow a 30% or more reduction in water content.
Effect of Superplasticizers to Enhance the Properties of Concrete
This study aimed to study the effects of asuperplasticizing admixture, namely, Sikament-NN superplasticizer, on concrete properties, such as workability and compressive strength. Experiments were
- What is superplasticizer in concrete?
- Superplasticizer in concrete is also known as high performance water reducers or high-range water reducing admixture. Compared with ordinary water reducers, superplasticizers have a higher water reduction rate, which can reach 12%~25%, or even higher. At the same water-cement ratio, superplasticizers greatly improved the workability of concrete.
- What is a superplasticizer used for?
- Superplasticizers (SPs), also known as high range water reducers, are additives used for making high strength concrete or to place self-compacting concrete. Plasticizers are chemical compounds enabling the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more.
- What is high-efficiency concrete superplasticizer?
- High-efficiency concrete superplasticizer is a chemical admixture that can significantly improve the workability of commercial concrete and significantly reduce its mixing water volume. It is one of the important products in the pillar industry of new building materials.
- What is the difference between superplasticizers and water reducers?
- At the same water-cement ratio, superplasticizers greatly improved the workability of concrete. It’s easier to prepare high-flow concrete with a slump of up to 25cm without producing too much air entrainment, and do not cause excessive retarding of concrete, while the slump of concrete mixed with ordinary water reducers is usually around 10cm.
- What is the difference between a plasticizer and a superplasticizer?
- Plasticizers are chemical compounds enabling the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent. Plasticizers and superplasticizers also retard the setting and hardening of concrete.
- Are polycarboxylate superplasticizers good for concrete admixture?
- Polycarboxylate superplasticizers have become one of the most important superplasticizers in the concrete admixture market, that’s due to its outstanding advantages, such as high water-reducing rate, good effect, good adaptability with cement, and slump protection performance.
