1. TECHNICAL DATA SHEET 105 - HB RAK NS GROUT (SPECIAL CEMENT MODIFIED NON - SHRINK GROUT) RAK NS GROUT HB is a pre - mixed, special cement modified c ementitious non - shrink grout which requires only the addition of water to obtain a free flowing non - shrink grout of excellent performance. 105 RAK NS GROUT (No n Shrink Gro ut) 105 RAK NS GROUT (N o n Shri n k Gr out ) ADVANTAGES RESISTANCE TO HIGH TEMPERATURE: ORDERING GUIDE • on - shrink • Pre - mixed and packed to avoid site variations and errors • High bond strength to steel and concrete • High early strength characteristics for rapid return • Adjustable consistency • High strength, impact resistance and durability • Non - shrink properties give maximum contact with bearing surfaces • Can be used up to a 80 mm thickness between plate and foundation RAK NS Grout can withstand high temperature (+400°C) for very long periods without deterioting substantially. PRODUCT NO. 105 STANDARDS ASTM C - 191, 878, 230 ASTM C - 827 - 78 PACKAGING 25kg Paper / Plastic Bag COLOR Grey RESISTANCE TO CHEMICAL ATTACK RAK NS Grout is watertight and is protected against environmental aggressive agents in solution. STORAGE RAK NS Grout should be stored in dry premises, away from direct sunlight, wind and humidity APPLICATION Mix the powder with measured quantity of water for a minimum of 5 minutes to obtain a smooth, uniform lump free consistency. Approximately 4.5 - 5.5 liters of water is needed for 25 kg of powder. Pour the grout continuously to eliminate air pockets. For a thick consistency, 3.5 - 4. 5 litres of water should be used and for dry packs 2 – 2.5 liters of water should be used.
