ZS-Masonry Cement Grinding Aid
1. Product Introduction
What is ZS-Masonry Cement Grinding Aid?
ZS-Masonry Cement Grinding Aid features a core combination of water-retention components, foam-stabilizing/air-entraining agents, and a mild alkanolamine strength-enhancement system. It is tailored for masonry cements with low-clinker ratios and high levels of limestone and fly ash. The product boosts grinding efficiency and output while optimizing mortar water retention, workability, and bond strength, effectively addressing common issues such as poor water retention, cracking due to rapid water loss, poor workability, and low strength.
How Does It Work?
Grinding & Dispersion: Adsorbs clinker, limestone, and fly ash particles; neutralizes static electricity to prevent balling and caking; refines powder and optimizes particle size distribution; increases hourly output and reduces grinding energy consumption.
Micro Air-Entraining: Contains built-in micro-air-entraining agents that generate uniform, tiny air bubbles, enhancing mortar smoothness and workability during plastering.
Water Retention: Polymer water-retention components lock in mixing water, achieving a water retention rate of ≥85%; prevents rapid moisture loss after application, thereby reducing the risk of hollow spots and cracking.

5. Frequently Asked Questions
Q: How is the optimal dosage determined?
A: The recommended range is 150g – 300g per ton of cement. Exact dosage depends on clinker grindability, mill type, and SCM content. Our technical team can assist with mill trials.
Q: Will adding this product cause excessive air entrainment or a significant drop in strength?
A: No. The formulation allows for controlled, micro-level air entrainment, producing fine, uniform bubbles that improve workability while steadily enhancing strength. Issues such as oversized voids or marked strength reduction do not occur.
Q: With a low clinker content, is the strength enhancement sufficient?
A: Yes. ZS-Masonry Cement Grinding Aid is formulated with multi-component active activators optimized for limestone and fly ash systems. It effectively compensates for strength even at low clinker ratios, consistently meeting M5, M7.5, and M10 grade standards.
Q: How should the product be stored?
A: Store in a sealed plastic container at room temperature. Protect from freezing in winter. Do not store with strong acid additives. Shelf life: 6 months.

7. Usage Guidelines
Calibration: Install a dedicated metering pump and calibrate to target dosage. Addition point: clinker feed belt or mill feed port.
Application Point: Apply evenly onto the clinker feed before entering the mill.
Monitoring: Track mill amperage, production rate (t/h), and cement quality (Blaine, residue).
Note: We provide methods for detecting and controlling the feed rate.
