Polydos SR 830

High-Performance Superplasticizer Concrete Admixture

Standard
Ministry of Public Works Specification No: 04.613/1-A3
TS EN 934-2 Tables 11.1 and 11.2: Set retarding / high-range water-reducing / superplasticizer concrete admixture

Description
Polydos® SR 830 is a new-generation, polycarboxylate-based high-performance superplasticizer designed for concrete production. It is particularly suitable for producing concrete mixes that require high early strength development, high water reduction, and excellent flowability.

Fields of Application

• Ready-mixed concrete production requiring long-distance transportation in hot climate conditions

• To compensate for consistency loss in hot, windy, and humid weather

• Concretes requiring excellent flowability and workability retention

• High-quality and high-strength concrete production

• Densely reinforced concrete structures that are difficult to place

• Concretes requiring dense and smooth surface finishes

• Production of impermeable concretes

• Architectural, structural, and decorative concrete applications

• Elements with complex geometries requiring detailed and intricate formwork

• Used in the production of self-compacting concrete (SCC)

Features / Advantages

• Maintains workability for long durations during hot seasons without the need for re-tempering

• Prevents rapid slump loss and provides extended workability depending on cement type

• Enables high unit weight and mechanical strength

• Results in concrete with fewer voids, smooth surface finish, and lower permeability

• Allows easier placement and faster strength gain, leading to labor savings and earlier formwork removal or reuse

• Reduces carbonation rate and improves mechanical properties such as shrinkage and creep

• Ensures long-distance pumpability

• Significantly improves early strength development

• Greatly reduces mixing water requirement

• Provides excellent self-compacting capability to the concrete

Dosage
For flowable and self-compacting concretes, it is recommended to use 0.5 – 2.0 kg per 100 kg of binder (cement – microsilica – fly ash).
The dosage may vary depending on the aggregate properties, concrete class, water/cement ratio, water quality, and ambient temperature. Therefore, it is advised to determine the optimal dosage by conducting preliminary laboratory trial mixes.
While adjusting workability, the high water-reducing effect of the admixture should be taken into account and adding excess water to the mix should be avoided.
