Concrete plasticizers

گالن 20 - 220 - 1000 لیتری

The NR100 concrete superplasticizer is a polymer‑based admixture that can significantly reduce the water content of concrete without affecting its workability. This product also increases the strength and overall quality of concrete, making it more efficient and effective in practical applications.

NR100 Concrete Superplasticizer – ZORLU Chemical

Mechanism of Action

The mechanism of NR100 is based on polycarboxylate ether (PCE) technology. When PCE is added to the concrete or cement mix:

Coating of Particles: PCE molecules form a thin layer around cement particles, completely covering them and promoting separation.
Side Chain Repulsion: The side chains of the PCE create electrostatic repulsion between particles.
Main Chain Hydrophobic Effect: The hydrophobic main chain interacts with cement particles, rearranging water molecules away from cement surfaces.
Result: The mix becomes more fluid, slump is increased, and cement hydration is enhanced over time.

Quality Identification:

Color: Ideal is honey‑like. Dark brown suggests non‑PCE materials.
Viscosity: Should feel like oil, with a uniform, sediment‑free appearance.

Dosage

Standard Range: 0.3% – 0.8% of cement weight.
The exact dosage depends on trial mixes, climate, and material properties.
Overdosage may cause delayed setting, especially in sulfate‑resistant cement. Consult ZORLU Chemical for special cases.

Properties & Effects

Maintains workability for up to 30 minutes.
Prevents bleeding and segregation.
Suitable for thin and densely reinforced formworks.

Method of Use – NR100 Concrete Superplasticizer (ZORLU Chemical)

Dosage Calculation:

Determine the required amount of admixture based on the cement content of the concrete mix.
Dilution:

Dilute the calculated amount of superplasticizer with twice its volume of mixing water.
Addition to Mix:
- Gradually add the diluted admixture into the fresh concrete during mixing.
- Ensure uniform distribution by adding it steadily, not all at once.
Application Points:
- Can be added in the batching plant during production or directly into the truck mixer on‑site.
- If added to ready‑mix trucks, ensure thorough mixing before pouring.
Mixing Time:

Mix for a minimum of 1 minute per cubic meter of concrete to achieve proper dispersion.
Important Note:

Never pour the superplasticizer directly onto dry cement. Doing so can reduce efficiency and compromise performance.
