MABNA P-R-16 retarding Superplasticizer Concrete

MABNA P‑R‑16 Concrete Superplasticizer is used to enhance concrete workability either at the batching plant or at the project site.

With set‑retarding and slump‑retention characteristics tailored for hot‑season concreting, it is an excellent choice for reducing the water‑to‑cement ratio in tropical and hot‑climate regions.

It also increases concrete strength (typically up to the 35 MPa grade) and enables the development of economical mix designs during summer.

This product belongs to the third generation of advanced admixtures, formulated on modified polycarboxylates, which deliver:

• Significant reduction in mixing water,
• Increased flowability,
• Retention of concrete workability for extended durations (typically 1 – 4 hours).

MABNA P‑R‑16 is engineered for producing:

• High‑Performance Concrete (HPC)
• High‑Strength Concrete (HSC)
• Self‑Compacting Concrete (SCC)
• Durable, low‑permeability concretes

• Main Applications

  • Production of high‑strength concrete at batching plants.
  • Long‑distance transportation of concrete in hot weather (up to approximately 2 hours).
  • Production of Self‑Compacting Concrete (SCC).
  • Concreting in very large sections where significant placing time is required.
  • Concreting in thin sections with congested reinforcement.
  • Increasing 3‑day and 7‑day compressive strength compared to mixes without superplasticizer.
  • Manufacture of concrete using crushed aggregate.
  • Casting of slabs, foundations, columns, walls, bridges, and similar structural elements.

  • Advantages

    • Reduces the water‑to‑cement ratio, increasing compressive strength and durability of concrete.
    • Maintains slump and workability for 1 to 4 hours (depending on conditions).
    • Minimizes shrinkage and thermal cracking.
    • Reduces permeability to water, chloride ions, and sulfates.
    • Improves abrasion resistance and durability against freeze‑thaw cycles.
    • Prevents bleeding and segregation.
    • Allows reduction of cement content by approximately 10% to 20% (depending on materials and mix design) without compromising strength.
    • Compatible with supplementary cementitious materials such as silica fume, fly ash, and slag.
    • Suitable for concreting in hot climates and for mixes requiring long transport times.
    • Enhances cohesion and plastic viscosity in concrete.
    • Further decreases overall concrete permeability.
    • Does not delay long‑term compressive strength development.
    • Fully compatible with all types of Portland cement and pozzolanic materials such as silica fume.
    • Prevents cracking due to shrinkage and concrete contraction.
    • Eliminates cold joints in prolonged pouring operations.

• Storage Conditions:

  • • Shelf life: One year when stored in the original, unopened packaging under suitable conditions.
    • Recommended storage temperature: Between +5 °C and +35 °C.
    • Protection requirements: Keep away from frost and direct sunlight.
    • Packaging: Available in 20 kg plastic containers and 1000 kg IBC tanks.
