Ultratech Powergrout NS2 SP, For Construction, 40 Kg

Product Details

UltraTech POWERGROUT NS2 is a cement-based, non-shrink, non-expanding, polymer enriched, high performance, high early strength and high quality binder for precision grouting applications. POWERGROUT NS2 is developed by using special polymers, additives and selected fillers. Variants POWERGROUT NS2 FLOWABLE POWERGROUT NS2 NORMAL Areas of Application METHOD OF APPLICATION Features & Benefits Specification Ready-to-mix single component system, no hassles of mixing the ingredients Excellent bond strength Non-shrink, Non-expandable grout Economical with graded coarse aggregates for higher volume applications Subsequent usage time in 24 hours Ultimate compressive strength Consistent in quality Enhanced flow properties and pot life Self-compacting in nature No bleeding and better consistency UltraTech POWERGROUT NS2 is recommended for grouting with design strength of 80 MPa for foundation base plates, machine foundations and beds, which demand high strength for micro piles and pile caps, shear wall bond beams, for fixing and anchoring the precast elements, for manufacturing of high strength pavers and blocks. Surface Preparation Prepare the surfaces before the application of UltraTech POWERGROUT NS2 by removing oil, bond inhibiting agents, dirt, dust and laitance with suitable methods like by using wire brush, water jetting, mopping, etc. Proper checking of reinforcement and other elements to be grouted need to be carried out as per the structural requirements before placing UltraTech POWERGROUT NS2. The shuttering has to be proper without any gaps or loose materials to ensure nil leakages during the usage of UltraTech POWERGROUT NS2 Appropriate anti-corrosion and bonding agents to be applied over the old and renewed reinforcement bars and metal areas and over old-new concrete joints before grouting Mixing UltraTech POWERGROUT NS2 requires 14-15 % of water by weight of material Add UltraTech POWERGROUT NS2 to the measured quantity of water with constant stirring using a mechanical mixing device. Mix to a thick lump-free consistency Allow to stand for 2 minutes for the mix to mature and then remix to use. Do not add any extra water to alter the mix consistency or to extend the pot life Further water additions will hamper the strength and adhesion properties of UltraTech POWERGROUT NS2 Addition of upto 12 mm down well graded aggregate in 1:0.5 ratio by weight can be done as per the site requirement For specific high volume applications addition upto 20 mm down well graded aggregates can also be used at 1:0.5 ratio Application Use the mixed UltraTech POWERGROUT NS2 to the prepared substrate using the appropriate pouring technique UltraTech POWERGROUT NS2 should not be vibrated with any mechanical vibrators as it is self-compacting by itself Any external vibrations will segregate the mix and there are chances of changes in the product performance from the designed properties Curing is required only for extreme climatic condition of application
