MCON NSG 40

1. Use mechanical mortar mixers, preferably of the slow speed (250-350 rpm) paddle mixer or revolving drum type mixer. Hand mixing rarely achieves the desired result. Allow approx 5 minutes for mixing.

2. Thorough mixing is essential for achieving maximum results. Add MCON NSG 40 slowly into recommended amount of clean water in a mixer. Use as little water as is required for ease of placement.

3. Placing conditions, including temperatures may require mixing water adjustments as may be essential for practical purposes. Small trial batches to ascertain the best working consistency for the operation are recommended.

1. After completion of concreting work the open edges shall be cured by applying suitable MCON CURE CC or any other effective curing membrane manufactured by MCON.

2. Other curing methods, such as covering with plastic sheet, wet hessian cloth are also accepted.

1. Dual Expansion – Expands in plastic state as well as post initial setting.

2. Low water permeability – excellent resistance to ingress of water so can be used in Tie rod holes grouting.

3. Pre packed – Factory controlled mixing avoids onsite batch mixing variations

4. Free Flow – Ensures that the grout easily reaches in all slots of the grouting area.

5. Over Head & Underground – Can be used in below the ground applications like piling.

Surface Preparation

1. The substrate surface must be free from oil, grease or any loosely adherent material.

2. If the concrete surface is defective or has laitance, it must be cut back to a sound base.

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

Application

1. In order to prevent air voids apply mixed MCON NSG 40 from one side or corner only. MCON NSG 40 should be placed within half an hour of mixing.

2. Flowable mix may be used with low pressure cement grouting equipment or may be hand rodded into restrained sections. High points must be adequately vented to allow entrapped air to escape. Plastic mortar may be rodded into place.

3. Consistency can range from thick cream to smooth plastic.

4. For large volume of placement areas MCON NSG 40 may be pumped with a heavy duty diaphragm pump, screw or any other standard pump.

5. MCON NSG 40 shall be used in the thickness range of 20mm to 100mm in single pour. For thickness of a section is more than 100mm, 50-70 % (by weight of MCON NSG 40) 6-10mm down washed coarse graded aggregate shall be used to reduce temperature built up in the hardened grout.

2. Anchorage of bolt and steel bar

3. Base plate grouting of cold as well as hot rolling mills in steel plants.

4. Grouting of bearing pads

5. Grouting of heavy Turbines base
