Five Star* grout - Direct Chemicals

1 General-purpose, shrinkage-compensated, cementitious groutfor dry packing, grouting, boltfixing and bedding of machineryFive star * grout five star groutis shown to beeffectively non-shrink by ASTM C827 Early Volume Change ofCementitious Mixtures which, unlikeother methods, measures expansionor shrinkage from time of placing Volume expansion to ASTM C827when unrestrained is greater than1 0% Precision grout suitable for use overa range of temperatures and siteconditions Can be pumped, poured, trowelledor dry packed Does not contain iron, aluminium orother additives which have notwithstood the tests of time Thermal expansion similar to that ofgood quality concrete Good flow properties Can be applied in thicknesses from10 mm to 100 mm Does not significantly loseworkability during pot life Under stanchion plates andmachinery (static loads only)

2 Grouting bearings, precast units,floors etc Fixing anchor bolts, ballustrades,crash barriers, starter bars Underpinning Void fillingConstraintsFive star groutmust only be used inconfined situations, under baseplates, inholes and benefitsconstruction 2007 Uniclass L642 five star groutis a premixed cementitious grout developed for applications where aneconomical grout with good flow and strength is star groutis based on specially selected Portland cements, graded aggregates andadmixtures including a special form of carbon. This special formulation produces a grout which conforms to ASTM C827 Early VolumeChange of Cementitious Mixtures. It does not contain iron, aluminium or other additiveswhich produce non-shrink characteristics by chemical reaction. This eliminates any subsequent problems of dimensional instability, corrosion or star groutis designed primarily as a flowing grout but can also be used at atrowellable or dry pack this productAll tests carried out at max.

5 five star groutneeds only to be mixed withsufficient water to give consistency should be carried out in a proprietarygrout mixer or by using a medium speeddrill (650 rpm) with an MR4-type obtain the consistency required, addwater as follows:Dry pack mix: approx. 2 25 litres water per 25 kg bag. Trowellable mix: approx 3 5 litres water per 25 kg bag. Pourable mix: up to 5 litres water per 25 kg entraining excessive quantities of airduring surfaces should be clean and surfaces must be free from anycontamination including oil, grease, laitanceand dust and for maximum bond, thesurface should be roughened andpre-soaked with clean water. Immediately prior to grouting, remove freewater including that in bolt holes orrecesses. Metal surfaces must be free from rust, scale,oil or grease but removable metal shimsshould be lightly oiled.

6 Ensure bolt holes are free of dust, water orany loose material. Formwork should be wellsealed to prevent pouring, the area to be groutedshould be shuttered and a header box usedto maintain a grout head of 150 200 mmduring the pour. Machine mixing isrecommended to achieve continuouspouring. For large applications five Stargroutshould be placed by pump and hasbeen formulated to give a 35 minuteworking time. It does not contain metalparticles; wear and tear on equipment issimilar to conventional sand/cement and placement can be carried outbetween +5 C and +40 C. In service, FiveStar groutwill perform similarly to othercementitious mixes based on Portlandcement in the temperature range of 20 Cto +150 grout flow is essential andsufficient grout and water should beavailable to be mixed to ensure there is nodiscontinuity of the the thickness of grout is greater than100 mm, use five star repair concrete.

7 The grout around the edges of baseplatesmust be finished flush with the sides bycutting the grout while still green afterstripping formwork. Cracking due toexpansion may result in such areas wherethere is no star groutis based on Portland cementand good concreting practice with regards toplacing and curing especially under winterconditions must be not add water above the recommendedstated only clean (potable) leaving unconfined areas of groutproud around bearings PreparationApplicationconstruction stored unopened in a dry place attemperatures above 5 C, shelf life is 12months from date of and shelf lifeFive star groutis supplied in 25 kgpolythene lined For a pourable mix each 25 kg bagproduces approximately litres of 71 bags per cubic metre. When using atrowellable mix the yield is 13 litres 77bags per cubic metre.
