SUBSTRATE QUALITY / PRE-TREATMENT

Concrete:

▪ The concrete shall be thoroughly clean, free from oil,grease,dust, loose material, surface contamina- tion and materials which will impair the grout flow or reduce adhesion strength.

▪ Laitance, delaminated, weak, damaged and deterior- ated concrete shall be removed to provide a structur- ally sound substrate.

▪ Any pockets or holes for structural fixings should also be cleaned of all debris.

Steel, iron:

▪ Clean, free from oil or grease, rust and scale etc.

Shutter/Formwork

▪ All formwork should be of adequate strength, treated with release agent and sealed to prevent leakage of pre-wetting water and grout.

▪ Ensure formwork includes outlets for removal of the pre-soaking water.

▪ A header box/hopper should be constructed on one side of the formwork so that a grout head of 150-200 mm can be maintained during the grouting opera- tion.


MIXING

▪ Tasir-sopecgrout01 shall be mixed using suitable grout mixing equipment combined with agitator for continuous large volume mixing. Volume capacity of equipment should be applicable to the volume of material being mixed for a continuous operation.Equipment trials should be considered to ensure product can be mixed satisfactory.

▪ Pour the minimum water ratio in the correct propor- tion into the mixer. While stirring the water, slowly, add the powder to the water.

▪ Add more water within the mixing time upto the maximum allowed until the desired consistency is achieved.

▪ Do not add more water than the maximum specified.

▪ Mix continuously for a minimum of 3 minutes. For larger mixes the mixing time shall be extended to ap- proximately 5 minutes or as necessary until the grout achieves a lump free smooth consistency.


APPLICATION

Pre-Wetting

▪ The prepared concrete substrate shall be thoroughly saturated with clean water for 12 hours before ap- plication of the grout.

▪ The surface shall not be allowed to dry within this time.

▪ Prior to application of the grout, all water shall be re- moved from the substrate.

Placing

▪ Immediately after mixing pour/pump the mixed grout into the header box/hopper ensuring continu- ous grout flow during the complete grouting opera- tion to avoid trapping air.

▪ For large volume placement, grout pumps are recom- mended. Equipment trials should be considered to ensure product can be pumped satisfactory.

▪ Surface finishing should be carried out to the re- quired surface texture as soon as grout has started to stiffen.

▪ After the grout has initially hardened, remove form- work and trim edges while concrete is ‘green’.

▪ For cold weather working consider using warm wa- ter to assist with achieving strength gain and main- taining physical properties.


CURING TREATMENT

▪ After the grout has initially hardened, remove form- work and trim edges while concrete is ‘green’.

▪ Protect the fresh material from premature drying and cracking using an appropriate curing method e.g. cur- ing compound,moist geo-textile membrane, hessian, polythene sheet etc.

▪ In cold weather apply insulated blankets to maintain a constant temperature to prevent surface damage.


CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened material can only be mechanically removed.


LIMITATIONS

▪ Keep exposed surfaces to a minimum

▪ Avoid application in direct sun and/or strong wind

▪ Use only on clean, sound substrate

▪ Substrate must be free of ice before application

▪ Do not exceed water addition

▪ Do not use vibrating pokers

▪ Do not add additional water during the surface finish- ing as this will cause discoloration and cracking

▪ To avoid cracking in warm temperatures keep bags cool and use cold water for mixing
