Cementitious Grout

Clients can avail from us Cementitious Grout that is non-shrink, expansive, high early strength, and high workability (flow) general purpose cementitious grout. The Cementitious Grout is made available under the brand name Kemgrout – GP. Cementitious Grout (KEMGROUT – GP), offered by us, is a nonmetallic, cement based grout with good (workability flow) and positive volumetric expansion. Cementitious Grout is chloride and iron free hence no corrosion & loss of cohesive strength due to corrosion by oxidation particles. The high early strength of cured grouts allows the immediate installation & operation of the machine or equipment. The grout sustains the high dynamic and static loads transfer by the running machine & equipment. The grouting height provision of the grout is 110 - 120 mm.

• Non metallic - no cohesion loss due to corrosion.
• Chloride free - no corrosion of steel.
• Good workability and flow-ensure larger contact.
• Non-shrink - duel shrinkage compensation - ensures volume stability.
• High early & ultimate compressive strength.
• Excellent bond between machinery and foundation.
• Nontoxic
• Nonhazardous
End Uses
• Grouting of bolt pockets & base plate of any machine & equipment.
• Boilers, pump sets, generators, turbines, stanchion bases & motors etc.
• Grouting of columns in precast constructions.
Directions For Use
• Surface Preparation: The concrete surface including bolt pockets shall be free of oil & greaseThoroughly wire brush the surface to remove dirty & dust. Remove Oil & grease, degreasing with xylene, Toluene or Trichloroethylene solvent. Hack the concrete surface for improvement in bonding.Wash the surface with water till it cleans to a original concrete substrate. Saturate the surface with water prior to grouting.
• Shuttering / Formwork Provide wooden or steel leak proof formwork to withstand operational stressers. Seal the gaps of formwork and concrete surface with Kemgrout -gp grout in thick mortat consistency by mixing with less quantity of water. Allow it to cure for 3-4 hours before starting of group pouring / placement.
• Mixing Grout mixer or freefall type concrete mixer is recommended.Selection of the grout / concrete mixer capacity will depend on the volume of mixed grout required. The mixer vessel / pot shall be clean & dry. Charge 80% of mixing water. The water must be clean, cold and chloride free. Start the mixer. Start addition of grout powder slowly & continuously for about a minute. Add 25-30 nos. of 5-10 cm size stones or coarse aggregate (clean & dry) for lumpsfree efficient mixing of grout. Add balance 20% of mixing water and mix for 4-5 minutes. Now the grout is ready for pouring / placement.
• Placement / Pouring Pour the mixed grout through a 10 cm wire mesh kept on a pouring vessel (200 liter fitted with 2 inch ball value at bottom end of the drum) keep the grout agitating by wooden baffle. make sure that the surface is saturated with water & damp .Excess water if any remove by hand pump or cotton waste. Pour the mixed grout from one side only to avoid air/gap entrapment. Provide 100 mm minimum exposed area (shoulder) of grouts at pouring end and 50 mm on the other end. Cover the grout exposed area by plywood or polyethylene (HDPE) sheet for retrain & evaporation of water. Incase grouting bed height exceeds 110 MM, mixing of 50 % by weight of 5 - 10 mm coarse aggregate (clean & dry) is recommended. Provide atleast 10 - 12 hours gap between two subsequent grouting operations.
Grout Quantity Estimation
• Quantity of powder grout required in kgs. = 2.1 - 2.2 x volume of grouting void in liters.
• (Consider about 5% in kgs. wastage and other contingencies while calculating the requirement)
Cleaning Of Tools & Equipments : Easily cleaned with water immediately after the use. Storage & Shelf Life : Store the material away from moisture, water & cover it by tarpaulin in unopen condition. Shelf life is 6 - 7 months from the date of manufacture Packing: 30 kg woven sack with a plastic liner.
