6 TOP SURFACE PREPARATION 6.0 PROCEDURE 6.1 J. A. Jones Construction Company Engineering shall map the surface of the entire pour delineating the areas that can be made to meet the required elevation and finish by grinding and the areas that must be chipped out to sound concrete and topped.

i 6.2 The areas requiring chipping and topping shall be chipped down to a minimum of one and one-half inch (It') below required elevation.

-1 6.3 After chipping to sound concrete and prior to any topping or grinding of other area, J. A. Jones Construction Company Engineering shall notify Ebasco Engineering that the. area is ready for inspection.

Any area containing unsound concrete shall be inspected by the Windsor Probe method.

In ver-Ifying the concrete soundness, the equivalent average 28 day compressive strength shall not be less than 5000 PSI and none of the equivalent com-pressive strengths shall be less than 4600 PSI.

1 6.4 Areas requiring grinding only to produca an acceptable surface shall be

-2 ground with suitable grinding machines un.til' acceptable by the Engineer.

Area shall be determined by estimating workable area that can be worked, based on " pot life" and required cooling time if repair requires more than one Inch (l") thickness, Reference 7.3.2.

7.1.2 Clean area to be worlied as follows:

7.1. 2.1 Chip to sound concrete.

7 1.2.2 Surface must be drye 7.1.2.3 Remove all dust, laitance, grease, and other foreign pa rt i cl es.

j 7.1.3 Straighten and support waterstop as required.

7.2 MIXING

7. 2.1 Mix Sikadur-Hi-Hixf Gel two (2) parts epo'xy per manufacturer's recomenda t ions.

Amount to be determined by area to be worked.

7 2.2 Measure Colma Quartzite Aggregate and mix one (1) part Sika-Hi-Mod Gel epoxy to one (1) part Quartzite Aggregate. Add aggregate slowly to binder while mixing.

~

7. 2. 3 Do not attempt to use after pot life" has expired.

By adding aggregate, it will add approximately five (5) minutes to " pot lifd'.

7.3 APPLICATION 7.3.1 Apply prepared, epoxy mortar to embed waterstop a,s required per attached sketch, Appendix A.

7.3.2 Apply mortar not to exceed one Inch (l") thickness.

If required mortar thickness exceeds one inch (l"), allow preceeding layer to cool before applying second layer.

Coolness can be determined when the mortar becomes hard.

It should be cool, approximately one (1) hour after mixing.

continue toward the front of the void.

Place concrete at a low rate of placement to allow sufficient' time for consolidation and removal of air.

By starting,the placing at the r. ear, the air will be forced out the front.

After the large opening of the void has been filled and consolidated, add forms ap required until concrete cannot be placed and vibrated into the large opening of the void.

Then add required forms *and " birds, mouth" and place concrete through the top,of the void at the surface of the slab.

Only place at a rate that can be consolidated.

Fill the entire void including the void on the surface and the drilled hole from the surface into the vold.

10.4 An expanding plug as detailed on attached sketch, Appendix "D',

shall be g

, fabricated for each hole to be pressure grouted, and coated with wax to g

prevent adherence of the epoxy.

Each plug shall provide a fill port and l

a vent.

The fill port shall be provided with a quick coupling and the l

j vent with a cap or valve for venting.

The supply line between the pressure pot and quick coup 1.Ing shall be provided with a sight glass for observing i

3 flow of epoxy.

l 10 5 The grouting operation shall begin with hole number 24.

Assure,that all l

holes are clean and dry, then pack hole number 24 with pea gravel from one 3

of the. sealed bags.

When the hole has been packed with the pea gravel, I

install the plug, as provided in 10.4 above.

Mix only-the amount that can be used in approximately 15 minutes or as directed by the Sika representative.

Place.the container of epoxy Into one of the g

paint pressure pots which has been connected to the quick coupling in the

l!

plug in' hole 24.

Apply air pressure as directed by Sika representative

-(approximately 10 PSI) to pressure pot and observe flow of epoxy in sight t

glass.

When the epoxy runs out, switch grout supply line to other pressure pot and continue grouting operation.

Clean first pressure pot grout supply line with Sika Equipment cleaner 650 while additional epoxy is being mixed.

Continue this switching and mixing operation until epoxy is observed passing I

Into one of the adjacent cored holes or abil.ity to move epoxy has ceased.

If epoxy cannot be moved by the 10 PSI pressure, increase the pressure by 5 PSI if increments until the epoxy begins to move' or until 25 PSI has been obtained.

If the epoxy cannot be moved at 25. PSI hold this pressure for 15 minutes.

-4 10.7 If epoxy is observed passing into one of. the adjacent cored holes, continue to hold pressure on the first hole, mix additional epoxy and fill hole which epoxy was observed flowing irr to, approximately half full with neat epoxy, pour small amounts of pea gravel into the hole and " rod" into the neat epoxy, continue adding neat epoxy and pea gravel until hole is full.

A SURFACING

("T i High-modulus, high-strength, AGENTS moisture-insensitive epoxy adhesive SIKA CHEMICAL / LYNDHURST. N..J. 07071 DESCRIPTION Sikadur Hi-Mod is a 1004-solids, 2-component, moisture-insensitive, epoxy-resin

. system. It is an all-purpose, high-strength, rigid adhesive designed for structural bonding of dry, can't -dry, damp, or wet structural materials free,of standing water. Especially suitable for bonding fresh plastic-portland cement-to sound hardened concrete, or, when mixed with granules, to prepare a high-strength grout to level base plates and to anchor bolts.

ADVANTAGES

. Unique, non-polusulfide bonding adhesive - - Sikadur Hi-Mod is a polysu1 fide-free adhesive for ' gluing

• plastic concrete to hardened concrete.

. High-strength adhesive for *can't-dru' surfaces - - Exclusive' formulation.

Patented curing agent makes Hi-Mod insensitive to moisture before, during, and after cure. Reduces need for job shut-down due to wet oonditions.

. Ercellent adhesive for grouting base plates and anchoring bolts. - When mixed with granules, Sikadur Hi-Mod produces a high-strength grout for base plates and to anchor bolts.

DESCRIPTIO.'{

SIKA CHEMICAL / LYNDHURST, N. l. 07071 Sikadur Lo-Mod Lv is a 1004-solids,1004-reactive, 2-component, moisture-insensitive.,

epoxy-resin system. Its low modulus of clasticity provides greater 'give' under stress due to impact and thermal change. Excellent for epoxy-mortar floor toppings and patching on dzy, can't-dry, damp, or wet structural materials that are free of standing water. LV's also an efficient penetrating impregnation to seal dry porous substrates.

ADVANTAGES

. Unique, low-modulus adhesive for *can't-dry

• surfaces ?, Patented, exclusive formulation of Lo-Mod LV makes it insensitive to moisture before, during, and after cure. Reduces need for job shut-down due to wet conditions.

. Impact, thermal-resistant toppings, patches, overlays, grouts - - Lo-Mod LV has an approximate minimum tensile strength of 3,000 psi and a minimum tensile elong-ation of approximately 5% for greater 'give' under stresses of impact and thermal change.

. Effective sealer for dru, porous concrete - - Low viscosity (lightweight oil) enhances penetration of dry, porous concrete. Also seals LV-mortar toppings.

Subject:

WATERFORD SES UNIT NO. 3 CONCRETE REPAIRS FOR PLACEMENT 499S02-10B The repair procedure for mat placement 10B, section 9.6, deals with waterproofing the repaired area. The extent of the waterproofing should be such that the entire length of the west face of placement 10B be water-proofed using W. R. Grace's bituthene to a depth as shown on the attached sketch. This will require excavating a trench along the side of the foundation mat, preparing the. surface and applying the waterproofing membrane .according to Ebasco specification LOU-1564.475. An additional 12 inches -of the waterproofing membrane wich a bead of bituthene mastic should ba installed around all edges. It should be also made clear that the repair of the voids o E She west face of placement 10B be made prior to concreting wall placements 565-1A, 499S04-4A-1 and 499SO4-8A-1. These walls are exterior vans located above the voids. .The concrete being used to repair these voids should also be anowed to reach design strength before these walls are placed. 23C/n Enclosure ec: A.
