ULTRATECH POWERGROUT NS1 Single Component Grouting Compound for Tiles (40 KG)

91 000 74051 Powergrout NS1 is a cement-based, high-performance precision grout / structural grout made by UltraTech. It's a single-component, polymer-enriched, non-shrink, non-expanding grout designed for heavy-duty structural grouting rather than light tile-joint filling. 🛠️ Where & How It's Used Powergrout NS1 is typically used for structural and industrial-grade applications, e.g.: Grouting under base plates of machines, heavy equipment foundations, bearing plates, columns, precast concrete elements. Anchoring bolts, dowel rods, heavy railings, or precast beams where load transfer and stability are critical. Repair works on concrete surfaces, potholes, structural void-filling, and other critical structural maintenance tasks. 🔧 Key Features & Benefits High compressive strength — design strength up to ~ 95–100 MPa at 28 days. Non-shrink and non-expanding — ensures dimensional stability after setting, critical in structural grouting to avoid cracks or settling. Self-compacting / flowable grout — flows easily into gaps and voids without need for vibration.Single-component (ready-mix) — just add water (≈ 16.5–17 % by weight) and mix; simpler than multi-part epoxies. Good bond strength and adhesion to concrete and steel — for stable anchoring and load-bearing. 📄 Technical / Use Specifications (Typical) Parameter / SpecValue / Detail Water-to-Powder Ratio ≈ 16.5–17 % for flowable mix Yield per 40 kg bag ~ 19–20 litres grout paste Design Compressive Strength Up to ~ 95–100 MPa (28 days) Standards Compliance ASTM C1107, ASTM 190, ASTM C 109, ASTM C 940, C 469, IS 4031, IS 2770, IS 5816 etc. Additives Allowed Can be blended with well-graded coarse aggregates (up to 20 mm) for large volume pours ⚠️ Important Use & Handling Notes Before grouting: surface must be clean — no oil, dust, laitance; reinforcement/steel surfaces should be clean, dry, and properly treated. Mixing: use mechanical mixer; mix thoroughly to lump-free consistency; let stand ~2 min, remix before pouring. Do not over-water to extend pot life — extra water will reduce strength & bonding. It is self-compacting: no vibration needed; using mechanical vibrators may reduce performance. For external conditions or harsh environment: proper curing (water curing for 3 days) may be needed depending on site.
