I have a 25,000 lb machine setting on a base of severly deterioated Embeco grout. What is the general opinion of grout properties in way of dampening vibration? To what degree can grouting influence or dampen machine vibration? The machine is a 6 stage IR Centac. 4 stage at one end, motor in the middle ,and a two stage booster at the other end.
Sep 23, 2016 · Grouting refers to all work to be carried out to properly fill the space between concrete surfaces and base plates of equipment, steel structures or concrete prefabricated elements. In concrete foundations (particularly machine foundations) grouting is used to achieve adequate transfer of horizontal and vertical forces.
Grout Consistency: The general rule is the less water added to a bag of grout, the stiffer the mix, and the corresponding higher compressive strength obtained. Grout mixed in a plastic consistency is suitable for smaller baseplates such as for columns or precast panels. Flowable grout can be used for small to medium size machine baseplates.
2. Grouting underneath base plates of machines. 3. Grouting of columns / stanchion foundations. 4. Grouting of crane rails, anchor bolts, dowel bars etc. ADVANTAGES 1. High early and ultimate strength: Perma Grout-60-White achieves a compressive strength of over 300 kg/cm2in 24 hours and strengths in excess of 600 kg/cm2 in 28 days. 2.
7.4 Construction Grout can be placed in thicknesses from 10 mm minimum up to 100 mm in a single pour when used as an under-plate grout. For thicker sections, it is necessary to fill / bulk out Construction Grout with well graded, silt free aggregate such as Conbextra Grout Aggregate, to minimise heat build up. Filling / bulking out of the grout ...
In cold wind farm we need to use thermal blanket to keep the grout warm. First of all pipe are lubricated with standard Portland cement slurry. Then, grouting is prepared in the mixing machines. We are using 2 machines in parallel because mixing time (minimum 7 minutes) is about 2 times the time needed to empty the mixer.

Aug 06, 2018 · The grouting of machine base plates and the anchoring/alignment equipment to a foundation provides a strong and rigid support between a machine and the foundation. The foundation and the anchoring of machinery to the foundation are key elements in determining long term geometrical alignment and key machine performance results.
Some specifications call for grouting of anchor pockets and under-plate bearings at the same time; this can lead to air entrapment and voids in the pockets, unless the grout is very fluid. Removable shims: Steel shims are used to provide the correct levelling and alignment of the baseplate which is then fixed in place using anchor bolts.

A Professional’s Guide on Grouting and Concrete Repair 3. In 2005, ASTM C 1107 was revised to where specific grades of nonshrink grout (Grades A,B and C) are no longer specified within the standard. Due to this revision, a precision nonshrink grout can no longer be specified using this test method.
Voids in the grout. The support provided by a grout is the Effective Bearing Area. This can be affected by grout leakage, unlevel plate, shrinkage of grout, inadequate mixing of grout, wrong placement method, poor grout flow or entrapped air voids. It can result in cracking and crumbling of the grout under the base plate.

By sloping out from the base plate you can get a little more bearing area on your pier. The grout allows a little play in the as-cast foundation height as gives you space for leveling. On exterior base plates the grout keeps water from sitting in the plate/pier joint. Not really compelling arguments for sure.
