Polycarboxylic acid water reducer mother liquor with high slump retention
-------XRT-E
XRT-E is a next-generation slump-retaining polycarboxylate superplasticizer (PCE) independently developed by our company, designed to significantly mitigate slump loss in concrete. This product is engineered for synergistic blending with high-range water-reducing PCE, making it ideal for applications in pumped concrete, ultra-fluid self-compacting concrete (SCC), high-strength/high-performance concrete (HPC), and commercial ready-mix concrete.
◆ Sustained Dispersibility: Time-release of dispersive moieties maintains fluidity for 90-120 minutes without compromising early
strength development.
◆ PH-Responsive Kinetics: Hydrolysis rate is self-regulating, accelerating as alkalinity increases during hydration.
◆ Steric Stabilization: Grafted polyether side chains (PEO) form a 15-20nm protective layer, preventing particle flocculation through
steric hindrance.
Slump Retention: Maintains ≥200mm slump flow for 2 hours at 0.15-0.25% dosage (ASTM C1437).
Compatibility: Fully miscible with Type I-V cements and mineral admixtures (fly ash, slag, silica fume).
Hydration Control: Retards initial setting by 60-90 minutes while enhancing 28-day compressive strength by 10-15%.
Pore Structure Optimization: Reduces capillary porosity by 25%, improving chlorideion penetration resistance (ASTM C1202).
| Application Field | Description |
|---|---|
| Concrete Preparation | Used for early strength, slow setting, precast, cast-in-place, flowable, self-compacting, mass, high-performance, and fair-faced concrete. Also for pre-mixed concrete in industrial and civil buildings. |
| Commercial Concrete | Applied in low-grade commercial concrete production. |
| Infrastructure | Utilized in high-speed railways, nuclear power, water conservancy, subways, and large bridges. |
| Key Projects | Used in major national projects such as highways and port terminals. |
| General Construction | Applicable to civil construction and commercial concrete mixing stations. |
◆ Recommended Dosage
The typical dosage ranges from 0.6% to 1.2% by mass of the total binder materials (cement + supplementary
cementitious materials). The optimal dosage should be determined through trials based on:
1. Cement type and fineness
2. Aggregate properties (particle size distribution, moisture content)
3. Target slump retention time
4. Ambient temperature and humidity conditions
◆ Compatibility & Formulation
1. Synergistic Blending: Can be combined with high-range polycarboxylate superplasticizers (PCE) to optimize
water reduction and workability retention.
2. Solo Application: Suitable for standalone use in standard concrete mixes requiring moderate slump retention.
3. Dosing Method: For best results, add the mother liquor during the mixing process after initial water addition.
