Powder vs. Liquid Polycarboxylate Superplasticizers

Comparison Table

Key Insights

• PC-1162: More general-purpose, designed for concrete (ready-mix, SCC, precast, high-strength).

• Liquiment® 1641 F: A solid-type PCE used broadly in cement admixtures; versatile but less specialized in mortar systems.

• Liquiment® / Melflux® 5581 F: Optimized for dry mortar applications (self-leveling, grouts, screeds). Strong in early strength development and fluidification of sulphates.

In short:

• If your focus is concrete production (ready-mix, SCC, precast) → PC-1162 is more suitable.

• If you need broad cement admixture compatibility → Liquiment® 1641 F works well.

• If your projects involve dry mortar systems (floor screeds, repair mortars, SLU) → Liquiment® / Melflux® 5581 F is the better choice.

Sectoral Suitability & Dosage Rates

Key Takeaways

• PC-1162 → Best suited for concrete applications (ready-mix, SCC, precast, high-strength).

• Liquiment® 1641 F → Optimized for cement-based admixtures, versatile in blended systems.

• Liquiment® / Melflux® 5581 F → Designed for dry mortar systems (floor screeds, grouts, repair mortars), with strong early strength and fluidity benefits.

• Melflux® Series → Broad portfolio covering both concrete and mortar applications, offering flexibility across dosage ranges.

Preparation

• PC-1162 is supplied in powder form.

• Before use, it should be pre-dissolved in clean water by slowly adding the powder while stirring.

• A mechanical mixer is recommended to ensure a homogeneous solution.

Dissolution

• The working solution is typically prepared at 20–40% solid content.

• The pH should be maintained in the range of 7–9.

• Dissolution should be carried out at room temperature; avoid high temperatures to preserve stability.

Usage

• Recommended dosage: 0.06% – 2% of cement weight.

• Dosage depends on cement type, water-to-cement ratio, and the desired workability and strength.

• For best performance, add PC-1162 in solution form directly into the concrete mix.

• Compatible with other admixtures, but pre-testing is advised to confirm synergy.

Storage

• Store in a dry, cool, and well-ventilated warehouse.

• Protect from moisture; once the package is opened, consume quickly to avoid clumping.

• Shelf life: 24 months in original packaging under proper storage conditions.

• Avoid direct sunlight and high temperatures.

Summary:

• Preparation → Pre-dissolve in water with mechanical mixing.

• Dissolution → 20–40% solution, room temperature, pH 7–9.

• Usage → 0.06–2% dosage, add as solution.

• Storage → Dry, cool, ventilated place; shelf life 24 months.

Frequently Asked Questions (FAQ)

1. What is the main difference between PC series, Liquiment®, and Melflux® products?

• PC series (e.g., PC-1162) → Primarily designed for concrete applications (ready-mix, SCC, precast, high-strength).

• Liquiment® 1641 F → A general-purpose polycarboxylate superplasticizer optimized for cement-based admixtures.

• Melflux® 5581 F and Melflux® series → Specially developed for dry mortar systems (floor screeds, grouts, repair mortars, SLU), offering strong early strength and fluidity.

2. Which product is suitable for which sector?

• Concrete (ready-mix, SCC, precast, high-strength) → PC series

• Cement admixtures → Liquiment® 1641 F

• Dry mortar systems (screeds, grouts, repair mortars, SLU) → Melflux® 5581 F / Melflux® series

3. What are the recommended dosage ranges?

• PC series (PC-1162): 0.06% – 2%

• Liquiment® 1641 F: 0.05% – 1%

• Melflux® 5581 F / Melflux® series: 0.05% – 2%  Dosage depends on cement type, water-to-cement ratio, and the desired workability/strength.

4. Should I choose powder or liquid form?

• Powder form → Longer shelf life, lower transport cost, ideal for international trade and storage.

• Liquid form → Ready-to-use, easier dosing, preferred in local ready-mix concrete plants for daily operations.

5. What is the CAS number?

• The most commonly referenced CAS number is 37199-81-8.

• Note: Polycarboxylate superplasticizers are polymeric blends, so CAS numbers may vary depending on the monomer base (TPEG, HPEG, APEG, MPEG).
