Engineering Grouts

We manufacturing a wide range of Construction Grouts (K-5 STONEHARD 60) which is high strength, free flow and non-shrink grout. Benefits : Prepacked, factory controlled consistent material needing only addition of waterShrinkage offset by expansion to ensure original volume is retainedFree flowing, self levelling grout l Easy placement and filling of under bases of machineryNon metallic and chloride free. Product :A Single pack ready to use, ultra high strength, free flowing, non shrink grout. K-5 STONEHARD 60 is a blend of specially processed cement and special fillers, free from corrosive substances and additives. Uses :Bolt pockets and base plate grouting of all equipment, Crane, stanchion bases and all type of machinery with dynamic load. Description : K-5 STONEHARD 60 is based on specially processed cement containing fillers and additives. K-5 STONEHARD 60 is supplied as ready to use grout requiring addition of precise quantity of water at site (3.750 to 4 Litre/25 Kg Grout). K-5 STONEHARD 60 is suitable for gap widths of between 10mm - 50mm. For width less than 10mm K-5 STONEHARD EP resin grout can be used (see separate data sheet for more information) for thickness in excess of 50mm. (say 75-100), cleaned washed 10mm aggregates can be incorporated at the rate of 50% - 100% of the quantity of grout used. Yeild : One pack of K-5 STONEHARD 60 will produces approximately 12.5 litres of grout when mixed with specified quantity of water. Typical Strength Development :Compressive strength : Average strength (Kg/cm 2 ) at flowable and pourable consistency. Pourable W/P=0.15Flowable W/P=0.16Days CS - Range Days CS Range 1 200 - 250 3 300 - 3507 375 - 450 28 500 - 650Properties : The water needs to be precisely measured and 25 Kg of K-5 STONEHARD 60 will require 3.750 litre for pourable consistency (W/P - 0.15) and 4 litres for flowable consistency (W/P - 0.16). Yield per 25 Kg : 12.5 lit.. approx : Pourable Life : 20 minutes : Application temp. : 10oC to 40oC; Expansion (% Vol): 0.8 to 1.5%. Flow : 20 to 25 cm on flow table. 315% at flow consistency.Instruction For Use : Mixing :(1) Place 80% of the water required in a concrete mixer [100% in case of a grout mixer].(2) Slowly add the required amount of K-5 STONEHARD 60 while continuously stirring for 1 minute. Add balance quantity of water (20%) and mix for 3 to 5 minutes. The mixed grout must be placed immediately and grouting must be continue till the cavity is filled. Surface Preparation :(1) All contaminated surfaces must be cleaned thoroughly by chemical or mechanical methods.(2) All bolt pockets and under bases must be free from dust, laitance and of sound substrate.If needed, substrate with water to allow for full absorption for atleast 24 hours. Just before the grouting is to commence, all water must be removed completely leaving the surface only damp.Bolt Pockets :Depending on the size of the bolt pockets, 50-100% cleaned 10mm sound aggregates by weight of grout consumption may be incorporated to economies on grout and also to keep the heat of hydration low. When the thickness exceeds 100mm-150mm our technical department may be contacted for advise. There must be atleast 12 hours gap between bolt pocket and under base plate grouting sequence. Mechanical mixing using a grout mixer or freefall concrete mixer is recommended. No hand mixing is permitted.
