Admixtures

Multiplast AirEnt

Multiplast AirEnt air-entraining admixture consists of surface-active chemicals that create small, stable air bubbles uniformly throughout a concrete mix. The bubbles are mostly under 1 mm in diameter, with a high proportion being smaller than 0.3 mm. The primary purpose of using Multiplast AirEnt is to enhance freeze-thaw and scaling resistance, thereby extending the service life of concrete. Improved cohesion and compaction further contribute to the durability and longevity of concrete structures. It is particularly suitable for durable concrete exposed to thermal fluctuations around the freezing point (0°C), lean concrete with a cement content of less than 250 kg/m³ and low fine sand content for pumping applications, and concrete with lightweight aggregates to improve homogeneity, workability, and overall application.

Multiplast AlkaSil

Aggregates form a major component of the concrete mix. Certain constituents in aggregates can react with alkali hydroxides in concrete. This reactivity is potentially harmful only when it causes significant expansion, typically becoming visible after a decade. This alkali-aggregate reactivity (AAR) has two forms—alkali-silica reaction (ASR) and alkali-carbonate reaction (ACR, sometimes called alkali-carbonate rock reaction or ACRR). ASR is more often a concern than ACR because reactive silica minerals in aggregates are more common. Multiplast AlkaSil is designed to prevent alkali-aggregate reaction.

Multiplast AntiShrink

Multiplast AntiShrink reduces both drying shrinkage and autogenous shrinkage. This shrinkage-reducing concrete admixture promotes expansion of the concrete at approximately the same volume that normal drying shrinkage contracts it. The net change in length of the hardened concrete is minimal, preventing shrinkage cracks. Multiplast AntiShrink admixture is ideal for situations where shrinkage cracking could lead to durability issues or where excessive shrinkage joints are undesirable for economic or technical reasons.

Multiplast AntiWash

Multiplast AntiWash is used for all underwater construction. In hydropower structures and for mass underwater concreting projects like the construction of weirs, concreting for dams, and the erection of caissons, concrete placed underwater is inherently susceptible to cement washout, laitance, segregation, cold joints, and water entrapment. Multiplast AntiWash makes concrete suitable for all types of underwater applications.

Multiplast Multichem

The usage of high-performance cements has been growing in recent years as a natural consequence of high-performance concrete production. For such high-performance cement, there is a need for economical and effective admixtures. This can be achieved by optimizing several parameters, ranging from clinker chemistry and reactivity to cement particle size distribution. The production of such high-performing cements at a reasonable cost, considering clinker content and energy requirements for high-fineness grinding, can be challenging. The use of Multiplast Multichem cement additives becomes necessary.

Multiplast ReProtekt

MULTIPLAST RePROTEKT is a special liquid concrete admixture that utilizes migrating corrosion inhibitor technology. It protects steel reinforcement, carbon steel, or other embedded metal in concrete. Corrosion induced by carbonation, chloride penetration, and other factors can be prevented using the RePROTEKT admixture. When added to the concrete mix, RePROTEKT diffuses to the surface of the reinforcement and forms a protective layer, thereby preventing corrosion.

Multiplast SpryCon

Sprayed concrete and plaster are fast-setting and hardening materials used for the stabilization and support of structures, as well as for concrete applications without the need for shuttering or molds. Multiplast SpryCon admixture enhances the use of machines to achieve multiple properties of sprayed concrete and plaster. With the increasing demand for underground infrastructure in India and worldwide, Multiplast SpryCon plays a crucial role in meeting this need. This method offers high construction speed and outstanding economic benefits, making it the ideal solution for many challenges.

Multiplast Super

Multiplast Super is a superplasticizer produced from processed sodium naphthalene sulphonate formaldehyde condensate and is supplied as a brown liquid. Cement particles tend to clump together, and Multiplast Super improves the dispersion of agglomerates within the concrete mix, ensuring more efficient cement usage. It enhances cohesion, reduces the risk of segregation and bleeding, and minimizes laitance and permeability. Increased density improves durability and resistance to aggressive agents compared to control mixes. Multiplast Super is a low-cost water reducer that can provide one or a combination of these benefits.

Multiplast Super R

Multiplast Super R100/R200/R300 are super plasticizers with retardation properties, produced from processed lignosulphonates and sodium naphthalene sulphonate formaldehyde condensate, and are supplied as brown liquids. Generally, cement particles tend to clump together, and Multiplast R100/R200/R300 works by improving the dispersion of the agglomerates within the concrete mix, ensuring that the cement is used more efficiently. It improves cohesion, reduces the risk of segregation and bleeding, and minimizes laitance and permeability. An increase in denseness enhances durability and resistance to aggressive agents compared to control mixes. Multiplast R100/R200/R300 are cost-effective water reducers that can provide one or a combination of these benefits. The retardation properties of Multiplast Super R products are highly suitable for high-cement construction. Delayed concrete setting reduces the heat of hydration, preventing thermal cracking.
