Superplasticizer Admixture

Increasing the strength and workability of concrete by reducing the amount of water used.
A concrete mixture is made up of a combination of cement, water, sand (fine aggregate), and crushed stone or gravel (coarse aggregate). Sometimes an admixture is added to improve the properties of this concrete.

Admixtures are liquid or powdery agents that are added to the concrete while it is being mixed. They enhance the properties of fresh and hardened concrete.

Retarding & plasticizer admixtures can delay the setting of concrete by a small percentage, or cause it to set slower by changing its water content. They can also reduce the likelihood of separation or bleeding between the concrete and surrounding surfaces, thereby improving the concretes durability.

Sika ViscoCrete 2100 is a plant-added high range water reducing and superplasticizing admixture that utilizes Sikas ‘ViscoCrete’ polycarboxylate technology to provide excellent plasticity while maintaining slump for up to 90 minutes, with controlled set times.

Enhanced Slump Life and Set Control:

With a sand ratio up to 25%, Sika ViscoCrete 2100 provides plasticized concrete with high slump. This is particularly useful when placing self-compact concrete that requires low water cement ratios to maintain a fluid and smooth consistency.

Suitable for use in both ready mix and precast applications, Sika ViscoCrete 2100 can be dosed in small amounts to obtain water reductions from 10-15%, or achieves water reductions up to 45% at high dosage rates.

Yeast fermentation waste (YFW) and fly ash are both biological additives that have been shown to be effective in the production of concrete. Their ability to bind the particles of cement in the concrete matrix makes them more effective in the production of stronger and more durable concrete, especially when the optimum water-cement ratio is reduced to as little as 0.25.
