    1. 1 Grouting of 2 skid-mounted ARIEL compressors with Chockfast Red & Red SG

    2. 2 Set up

    3. 3 Anchor calculations Before grouting the achorbols following data need to be checked or re-calculated: Required Bolt Force (kN) Bolt size Bolt length Pocketsize Planned torque (Nm) Groutlength Stretch-length

    4. 4 Preparation & grouting of the anchors

    5. 5 Install expansion joint rubber Expansion joints create ‘restricted’ areas in order to limit the flow of the grout Potlife (temperature) versus flowdistance will indicate the placement of the expansion joints To avoid shrinkage-cracks after the heatsink, joints are placed as a rule every 75-100 cm

    6. 6 Install shuttering

    7. 7 Some technical data - for 1 skid Total area to be grouted 9800 x 3430 mm Clearance 50 mm pouring hight (‘overpour’) 80 mm Total quantity of Chockfast Red® 54 units Anchordata (mm’s): 18 pcs M 30 x 3.5 class 8.8 L= 500 F= 200 kN Pocket ?200 x 200 x 375 L stretch 140 L grout 300 Actual elongation ? l 0.242 Torque 1200 Nm

    8. 8 Grouting the skid under the compressor The segment under the compressor could be reached properly by using several spiro tubes of Ř 125 with funnels, this enabled us to pour from the ‘inside’ as well.

    9. 9 Grouting the skid under the e-motor In contrast with the compressor part the area under the E-motor could not be reached (no man-holes were available in the skid) Consequently all grout had to pass through a slot of 50 x 1000 mm. consequently Chockfast Red® SG was applied

    10. 10 Reduction on material use Tight shuttering close to the contour of the skid avoided unnecessary coverage of floor
