ASTM C1107/C1107M-20 PDF Download

ASTM C1107/C1107M-20 is a standard specification for packaged dry, hydraulic cement grout (nonshrink). This standard is applicable for use in situations where a change in height below the initial placement height is to be avoided, such as in supporting structures or machinery. The grouts covered by this specification are made up of hydraulic cement, fine aggregate, and other ingredients, and they only require the addition of mixing water before use.

The standard provides detailed guidelines for the production of grout mixtures, including the prescribed conditions and equipment requirements. For smaller quantities, mortar-mixing apparatus is specified, while a clean, pre-wetted, and drained mixer is required for grout performance qualification. It is important that the mixer is free from hardened mortar and other foreign materials that can be removed with a trowel or hammer.

The standard also outlines the procedures for preliminary adjustment mixing and grout performance qualification, providing detailed instructions for consistency testing and determining the yield of the grout using a cylindrical measure.
