6.2. GENERAL SURFACE PREPARATION & APPLICATION

Foundations for Rotating / Reciprocating Equipment:

Surface preparation of foundations for rotating/reciprocating equipment will be done as per paragraph 4 of DEP 31.29.00.10-Gen., Installation of Rotating Equipment.

Special attention will be paid to the extent of the grouting. As mentioned in DEP 31.29.00.10-Gen., the foundation will be sized so that grouting can be extended to 50 mm beyond the base/sole plate or the shims.

If the size of concrete foundation is greater than the base/sole plate, formwork will be used to match the 50 mm.

Foundations for Steel Structures and Stationary Equipment:

The surface of the foundation under the base plate of the object to be grouted will be chipped and brushed to remove the weak upper layer of the concrete, damaged concrete and any oil-soaked concrete areas. Prior to grouting, loose concrete or dust will be removed, preferably by compressed air.

Before grouting commences the concrete surfaces will be soaked with clean water for 24 hours, unless the grout Manufacturer specifies otherwise.

QQQ AAA TTT AAA RRR

Grouting of Steel Structures and Stationary Equipment:

The installation of the grout will be carefully supervised.

Special attention will be paid to prevent distortion of the item being grouted.

The placing of sand-cement grout mortar will commence not later than 15 minutes after completion of the mixing. No grout mortar will be used that has not been placed after 30 minutes from completion of mixing.

Under no circumstances will re-mixing or knocking up be allowed.

Proprietary grouts will be mixed, placed and cured in strict accordance with the grout Manufacturer's instructions.

Vent holes should be drilled in base plates to avoid air pockets.

The grout will fill all voids between the base plate or sole plate and the foundation, and will have full surface contact.

Cement-based grout will be kept moist during the first 7 days after placing and will be protected from sunshine and drying out by protective covering as per DEP 34.19.20.31 Clause 10.3.2.

After hardening, wedges will be removed and the resulting voids filled with grout.

The grout thickness will be minimum 25 mm but will not exceed 50 mm.

Grouting will be extended 50 mm beyond the base/ sole plate if the concrete foundation is greater than the base/sole plate. Form work will be used to match the 50 mm.

The edge of the grout will be provided with a chamfer of approximately 25 mm.

The Gout is regarded as Non- shrink if its volume is not less than the Initial Volume, after Hardening for 28 days. During this period the test specimens shall have been completely protected against drying, evaporating, Carbonation and exposure to temperatures outside the range 230 C 30 C as per the DEP 34.19.20.31 Clause 10.1.2.

6.3. MATERIALS AND USAGE

Only materials approved by Contractor will be used. Fosroc - Conbextra BB 80 OR BASF-

Master Flow 928 T)

6.3.1) FOSROC CONBEXTRA BB 80:

It is a non-shrink cementitious bearing grouting (dry powder) material will be used Flanged Lighting Columns, Heavy stanchion bases and base plates for reciprocating pumps, anchor bolts, Steel Structures etc

The grouting material is packed in 25 Kg air tight plastic bags used up to the section thickness up to 100mm. For the thicker sections more than 100mm, the clean washed 5-10mm silt free aggregate will be mixed (Max.Ratio1:1) with the grouting powder as per the manufacturer recommendations.

Storage mixing & placing and curing shall be in accordance with the manufacturer recommendations.

T-4.234.076 Rev. C Page 9 of 30

QQQ AAA TTT AAA RRR

The grouting material will be mixed with a measured amount of clean water at WATER: POWDER ratio of 0.15 at a maximum temperature of 250C.Water Temperature will be Monitor by use of Thermometer.

The Compressive Strength of the grout must be 45 N/mm2 @ 24 Hours, 60 N/mm2 @ 3 days, 70N/mm2 @ 7 days and 85 N/mm2 @ 28 Days as per manufacturers data sheet recommendations and as per BS 1881 Part 116 1983.

6.3.1.1) PRE-SOAKING

Bolt holes and fixing pockets must be blown clean of any dirt or debris.

For a minimum of 24 hours prior to pouring, the area of cleaned substrate should be soaking with wet Hessian with fresh water to minimize localized absorption and to assist in the free flow of the grout.

Immediately before grouting, any free water should be removed. Particular care should be taken to blow out all holes and pockets.

Forms will be waxed or use of Silica as necessary to prevent sticking and leak proof as Conbextra BB 80 is a free flow grout. An intensive care will be paid to ensure that the grout cannot squeeze out from below and around the forms during placing and setting.

Ensure the Form work is secure and watertight to prevent movement and the area should be free from excessive vibration. Shut down all machineries until the grout has hardened.

6.3.1.2) MIXING & PLACING

For the best result, the grouting material shall be mixed with mechanical mixer for larger quantity. Dont use a colloidal impeller mixer for mixing.

To produce a fluid grout, add 3.75 Lit. of water (below 250C) will be to a 25Kg bag of Conbextra BB 80.The water should be accurately measured into the mixer. Slowly add the total content of the Conbextra BB 80 powder and mix continuously for 5 minutes on high shear / speed until the smooth and even consistency is obtained.

Place the grout within 15 minutes of mixing to attain full strength.

Conbextra BB 80 can be placed in thickness up to 100 mm in a single pour.

Continuous grouting operation will be takes place until the process is finished.

The mixed grout shall be poured only from one side of the void to eliminate the entrapment of air or surplus pre-soaking water.

6.3.1.3) CURING

On completion of the grouting operation, exposed areas should be thoroughly cured. This should be done by the use of continuous application of water with Hessian up to 7 days as per DEP 34.19.20.31 Gen Clause 10.3.2.

The Grouted area shall be covered with Wet Hessian with Polythene double Layer and/or as per DEP 34.19.20.31(Gen) Amendments plus Manufacture recommendation.
