HGT ÜNKA.3.03.TB.041 20/06/2011/06 Non-shrink / Tixothropic Grouting Mortar PRODUCT DESCRIPTION CONSUMPTION ÜNKA-HGT, is a ready to use tixothropic non-shrink grouting mortar reinforced with fibers and specialty chemicals. ~ 1900 - 2000 kgs of ÜNKA-HGT for 1 m3. AREAS OF USE ATTENTION ÜNKA-HGT, is succesfully used in the grouting of; ¥ Do not use where environmental and surface temperature is below +10¼C. ¥ Water should never be added to the product after the mixing process is completed. ¥ The remaining product should be kept closed airtight in its original packaging. ¥ During outside applications, the application area should be protected against direct sunlight, wind, rain and frost. ¥ tie rod holes, ¥ steel constructions, ¥ concrete anchors, ¥ machine foundations, ¥ foundation plates, ¥ guide rails for heavy construction equipment, ¥ precast panel joints, ¥ tank and reservoir piers... etc. where non-shrinkage and high adherence properties are required. ADVANTAGES ¥ provides high initial and final strengths ¥ tixothropic - non sagging ¥ balanced expanding ability eliminates shrinkage ¥ its strong, homogenous and watertight structure gives durability and resistance against mineral oils, sulphates and against freezethaw cycles ¥ Ensures perfect adherence to sound steel and concrete surfaces ¥ Its strong and specially selected mineral aggregate base gives perfect durability against extreme temperatures ¥ Does not contain harmful chemicals which can have negative effects on concrete and steel. ¥ Its non-corrosive nature and watertight structure makes it possible to be used just about anywhere, preventing corrosion. TECHNICAL DATA ¥ Color: Grey powder ¥ Unit Weight of Fresh Mortar: ~ 2,1 kg/lt ¥ Storage: 12 months when kept in a dry and closed area stacked in loads of maximum 5 bags ¥ Packaging: 25 kg craft paper bag with PE lining ¥ Standard: TS EN 1504-3 R4 (Structural Repair Mortar) HEALTH & SAFETY ¥ Contains cement. As it is an irritant material incase of contact, wash with plenty of water. ¥ Protective mask should be worn during the preparation of the product. ¥ Tools must be cleaned with warm water before the residues fully cure. The cured product should be removed mechanically. -compressive strengths @ 20¡C with 10cm x 10cm x 10cm moulds -flexural strength @ 20¡C with 160mm x 40mm x 40mm moulds compressive strength 1 day (N/mm2) > 30 compressive flexural strength 28 days strength 28 days (N/mm2) (N/mm2) > 50 modulus of elasticity > 10 ~ 38.000 APPLICATION Surface preparation: Concrete surface should be in a rough structure and both concrete and metal surfaces should be clean, free from oil, grease, rust and all loosely adhering particles. Absorbent surfaces should be saturated with water thoroughly. The wetting process should be made 24 hours prior to the application. The surface should be dampen just before the application once more and the excess water should be removed with a sponge. Absorbant moulds should also be saturated with water. Mixing the product: The water/mortar ratio is 1 : 8. ÜNKA-HGT is mixed with a low speed compulsory mixer. 80% of the mixing water should be poured into the container and ÜNKA-HGT should be added slowly while mixing. The rest of the mixing water is added according to the level of flow (consistency) desired. The mixing process should be continued until the mixture is free from all lumps and air bubbles. The mortar should be left to rest for 5 minutes after the mixing process. For applications above 25¡C, additional mixing water might be needed for desired flow. Additional use of mixing water for desired flow in hot weather conditions will reduce the final strength of the mortar. Therefore 3.8 kgÕs of mixing water should not be exceeded even in extreme (hot) weather conditions. The fresh mortar temperature must be below 30¡C. Do not use at temperatures below +10¼C.
