1.0 INTRODUCTION

1.1 PURPOSE 1.1.1 The purpose of this instruction is to provide installation methods for grouting under base plates, equipment bases other structural .

components or as specified on design document.

1.2 SCOPE l.2.1 Angle or Flat Base Plates

,_s, 1.2.1.1 The determination of which base plates require grouting shall be

( ) made by the responsible craf t support installation personnel or

\' . Civil Department craf t. This determination should be made prior to room / area turnover. ,

The maximum allowable gap under baseplates which does not require grout shall not exceed 1/16" for at least 80% of the base area.

The naximum thickness of epoxy grout for use under baseplates shall not exceed the followina values unless otherwise approved by the engineer via operational traveler or design document:

1. Insido containment: 1/2" thick maximum.
2. dutside containment : 1" thick maximum.

1.2.2 Equipment Bane  ;

1.2.2.1 Af ter completion of the curing of the cement grout placed per CCP-16, if gaps form between the cement grout and equipment base, gaps shall be filled per this instruction. Since verification of the size and extent of the gap is dif ficult on closed-in box-type equipment bases, grouting shall be in accordance with the instruction provided by engineering on an operation traveler.

4.2.1 Mix the entire contents of each of the following constituents as

, received from the TUCCO Test Lab

1. Ceilcote 658-N grout liquid (Resin)
2. Ceilcote Hardener 4-A
3. Silica Aggregate 4.2.1.1 Add the hardener to the resin component, stir thoroughly, approximately two (2) minutes until completely mixed. Pour this into the mixer or mixing container and add silica slowly and mix until it is uniform tan in color with no dry areas remaining. Pour this mixture into the grease gun or pump. Po t life is approximately 30 minutes at 70*F so small batches should be used and extra guns available.

4.2.1.2 If the grout is above 90*F prior to mixing, chill the sealed container to cool the material. If the temperature is less than 70'F the grout should be warmed to make mixing and handling easier. Best handling properties are achieved at 75'F 15'F, but it is not necessary to maintain these temperatures.

  • t 4.2.L.3 Clean mixing equipment with Ceilcote T-435, lacquer thinner, ketones or xylot.

4.2.1.4 Approximate work time of 658-N is 30 minutes at 70'F. Working time will be less above 70'F and more below 70*F. Best flowable mixture will be between 70'F and 90*F.

4.2.1.5 Ceilcote 658-N shall not be placed unless the surface temperature of the area to be grooted is at or above 50*F. Infrequent dips in tem-perature to 40*F is permissible during placement and/or cure; however, the elapsed time the temperature is below 50*F shall be added to the cure timo.

4.3 CURE OF CROUT 4.3.1 Cure of grout before placement into service, provided service area is ,

not submerged: '

Surface Temperatures Hours of Cure 50*=b9'F 72 hrs.

4.6 GROUT PLACEMENT 4.6.1 Base Plates 4.6.1.1 Inject grout through pre-drilled holes using grease guns or airless pump.

4.6.1.2 Repair of grout holes shall not be required.

1 4.6.2 Equipment Bases 4.6.2.1 Where possible, pressure grouting shall proceed in a fan-like manner from one side of base. As soon as grout is emitted from an adjacent

) hole and the grout is free of bubbles, injection may begin at that opening.

1 This step-wise procedure is continued until the grout is forced from all sides of the base plate or holes adjacent to the edge.

4.7 FORMWORK j 4.7.1 658-N grout is fluid which normally is pumped under pressure and a

form or " dam" shall be provided as required along the place edge.

, If necessary provide vent holes in the dam for air relief.

1

5.0 SAFETY PRECAUTIONS 5.1 This grout contains epoxy resin and polyamine hardener. Avoid direct 1 contact with skin or mucous membranes. Epoxy resin can cause ir-ettation to skin on prolonged contact and may cause sensitization.

Hardeners cause skin irritation, dermatitis, or other allergic re-sponses. Keep away from heat, sparks, and open flame. No welding i

should be permitted within 50 feet of the working area or directly

above. "No SM0 KING" signs should be posted in the working area.

Mix in a well ventilated area. Avoid excess breathing of vapors.

, In enclosed areas or where ventitation is poor, use an approved air mask and utilized adequate safety precautions to prevent fire or explosion. Protective gloves, clothing, and goggles should be

used when mixing and pouring grout.

August 1981 TECENICAL BULLETIN 9-9 Revision 2 65J-N TEHFE'ATURE RESIST.*.NT GROUT Ceilcote 658-N is a high temperature resistant, high strcngth epoxy grout. It was developed specifically to e'st the requirement of high strength a; high teeperatures including applications in the nuclear industry. 653-N Greut should be used for pressure injection grouting of base plates, hollow put; bases, and cracked concrete to fill, voids, cracks, and fissures. It has been tested at temperatures ranging from ambient to 350*F. in accordance with ASTM C-579 and Texas Utilities Services Specification, CP-EI-13.0-1 (" Procedure for Epoxy Grout Compressive Strength Test") and has been found to be sufficient for use both outside and inside containment areas. Testing temperatures were chosen to

  • simulate potential base plate temperatures inside containment areas.

l (O) COMPRESSIVE PROPERTIES

  • m T E?ERATURE COMPRES3IVE STRENGTH (PSI) 73'F. 15,600 125'F. 14,200 150'F. 13,800 200'F. 10,500 250*F. 6,150 300'F. 3,640 350'F. 2,620
  • These results represent actual' test data from one batch of material and )

do not reflect batch-to-batch variations. The minimum ambient temperature compressive strength (rejection criteria) is 12,000 psi.

RADIATION TOLERANCE TEST Ceilcote 658-N Crout (tested with Ceilcote 650 aggre6 ate), was exposed to 2 x 10 rads of gamma radiation in air at a rate of 0.9 x 107 rada per hour at Oak Ridge National Laboratories, Oak Ridge Tennessee. The flexural strength and modulus (

of elasticity were tested before and af ter exposure with no apparent effects. l CURE TDfE VS. TEMPERATURE Temperature affects the working time and curing time of 658-N Grout. At 70'F.,

the grout has an approximate working time of \ hour. Warmer teeperature m il shorten this tima; cooler will lengthen. The foundation being grouted will probably be cooler.than room temperature unless the room temperatura has Sean

/

O s

constant for some time. Temperatures vary so radically (day vs. night, day vs.

day) that field judgement must be used as the final measurement of cure and working

(

V) time.

PLACDfD*f 658-N Grout should be placed by means of pressure injection. Holes should be drilled to intersect cracks and voids to be filled. For more information on pressure grouting techniques, refer to Bulletin 9-1.8-1 for 647 Repair Grout (do not use mixing information for 647 Perair creut).

If the packaged grout is above 90*F., chill the sealed pails of greut liquid in a tub of ice or cover the pails with water-soaked burlap. It is not necessary to cool the grout below 70*F. In cold weather, materials should ba store? in a warm place. Lov terperatures make the grout stif f and hard to hedle. For best handling properties, the intredients should la at 75'F. t 5'F.

MIXING INSTRt'CTIt '!S These proportions are supirseded by those on the package label if they differ.

One Unit Ng 658-N Grout Liquid 8 lbs.12 oz.

Hardener 4A 1 lb. 4 oz.

325 Mesh Silica 15 lbs.

(Approximate yield 400 cubic inches per unit.)

Add the hardener to the resin component; stir thoroughly, approximately two (2) minutes until completely mixed.. Pour this into the mixer or mixing container and add silica slowly and mix until it is uniform tan in color with no dry areas remaining. Pour the mixture into the grease gun or pump. Pot life is approxi-mately 30 minutes at 70*F. so small batches should be used and extra guns available. If eaterial is supplied in other than the unit size listed above, field mixing proportions are as follows:

Parts by Weight 658-N Grout Liquid (100 parts)

Hardener 4A ( 14 parts) 325 Mesh Silica (171 parts)

Guns may be cleaned using Ceilcote's T-435 Solvent before the liquid grout gels.

Safety glasses should be worn while pressure injecting grout.

FLASH POINT: Pensky-Martens Closed Cup 658-N Liquid Above 230*F. (110*C.)

Hardener No. 4A 210'F. (99'C.)
