351.1R-12 Report on Grouting Between Foundations and Bases for Support of Equipment & Machinery
Published By | Publication Date | Number of Pages |
ACI | 2012 | 25 |
This report provides an overview of current practices of grouting for support of equipment and machinery. Materials and installation methods are described for epoxy and cementitious-based grouts used as the load-transfer material between equipment bases and their foundations. Characteristics of placed material, test methods for forecasting long-term performance, qualification of grout materials, foundation design and detailing considerations, and installation procedures are described. Keywords: bleeding; consistency tests; curing; durability; epoxy grout; cementitious-based grout; equipment grout; formwork (construction); foundations; grout; hydraulic cement grout; inspection; machinery grout; mixing; placing; sand-cement grout; stiffness; strength; tests; volume change.
