DESCRIPTION
KKS® GROUT 80 is a ready-mixed cementitious grout with selective aggregates, just add water to create a unity mixture with excellent flow, shrinkage compensated, self levelling, suitable for normal pumping or pouring. Early compressive strength development speed of this product is super high, and extending working time is suitable for large application areas.
ADVANTAGE
•    Quality stability - the product is packaged and pre-mixed at the factory.
•    High flow and self-leveling.
•    Excellent flow-ability for both pouring and pressure pumping.
•    Shrinkage compensated feature provides an excellent base. 
•    Fast growing strength allows early loading.
•    Compressive strength, bending strength and adhesion is ultra-high.
•    Non-chloride, will not rust, bleed, or harm metal on contact.
•    Great waterproofing, non-toxic, non-corrosive. 
USE
•    Widely used in pressure pumping construction and repair mortar.
•    Can be used for repairing some structural components such as panels, prefabricated walls, foundation base; repairs for beams, columns and post-tensioning structures. 
•    Can be used in the pressure pumping construction into the gap between concrete structures and precast concrete. 
•    The high early strength property is suitable for work that requires early loads including machine bases structural columns, restressed girders, bridge bearings, rail posts and seating’s bolt etc.

APPLICATION
SUBSTRATES PREPARE
Surface must be clean, free from oil, grease and other contaminants. Moisten with water but do not leave the water remains on the surface before application KKS® GROUT 80. 
For floor or concrete repair in large areas, suitable adhesives should be used, such as KKS® LATEX 310, 315.
MIXING
Mix with proportion of water/powder is 14% (about 3.5 liters per 25 kg bag).
To achieve the desired results, use a mortar mixer. Do not mix it by hand.
Pour 80% of water into the mixing tank, add the flour slowly and mix at least 3-4 minutes until the mixture becomes plasticizer, add the remaining water and mix to reach the required flow.
Pour mortar after mixing to release the air bubbles that created during the mixture.
APPLICATION
Construction of grout must be rapid and continuous from one side, without interruption to avoid bubbles trapped in grout. Ensure formwork is firmly placed and watertight, pour the grout to fill and full. Do not use the machine, just use the iron rod or wood to compact. For KKS® GROUT 80 to achieve optimum expansion result, apply mortar as quickly as possible, preferable within 15 minutes after mixing.
CLEANING OF TOOLS 
Clean with water as soon as the equipment is no longer used.
CURING 
Protect by covering as much as possible the mortar’s surface to avoid the premature of drying out, the regular curing methods also help, such as: moisturizing with water, covered with wet burlap, other equivalent measures, or using KKS® CURING 810 as curing agent.
