Cementitious ULTRATECH POWERGROUT NS3, 40 KG

91 000 74051 Powergrout NS3 is a cement-based, polymer-enriched, non-shrink, non-expanding precision grout designed for structural/industrial-grade applications. It belongs to the "Industrial & Precision Grout" line of UltraTech's building-products range. It comes in two variants: NS3 Flowable and NS3 Normal — allowing flexibility depending on site needs. ��️ Where & How It's Used Powergrout NS3 is suited for structural and medium-heavy grouting jobs such as: Grouting micropiles, pile caps, shear-wall bond beams. Fixing and anchoring precast elements, fasteners, rails, structural anchors. Manufacturing high-strength pavers & blocks, and concrete repairs where a strong binder and grout is required. �� Key Features & Benefits High early & compressive strength — design strength ~ 55–60 MPa (flowable variant) under recommended conditions. Non-shrink and non-expanding — ensures stable, reliable grouting without cracks or voids. Self-compacting / Flowable (in flowable variant) — flows into gaps/voids without need for vibration, making placement easier. Single-component, ready to mix and use — no need for multiple additives or complex mixing; reduces on-site hassle. Good bond strength & durability — ensures stable anchoring and long-term performance under load. Economical for high-volume applications — coarse aggregates (e.g. up to 12 mm–20 mm) can be added (in recommended ratio) when larger volumes are needed. �� Typical Specifications Parameter / PropertyValue / Detail Design Compressive Strength ~ 55–60 MPa (Flowable NS3) Mixing Water-to-Powder Ratio ~ 14–15% by weight (some sources list 10-10.5% depending on consistency) Yield per 40 kg Bag ~ 19–20 L (at ~15% w/p ratio) Compliance Standards ASTM C1107, ASTM 190, ASTM C940, ASTM C469, ASTM C348; Indian standards IS 4031, IS 2770, IS 5816. Application Time / Pot Life Typically up to 24 hours for subsequent usage (depending on ambient conditions) ⚠️ Important Usage / Handling Guidelines Surface must be clean — free from dust, oil, laitance, bond-inhibiting agents before grouting. Mixed grout should not be over-watered; adding more water than recommended reduces strength and compromises bond. Do not use mechanical vibration when placing — because grout is self-compacting; vibration may lead to segregation and weakness. For external or exposed applications: may require proper curing, depending on ambient conditions.
