ASTM C1107 FREE DOWNLOAD
Thirty-minute-old grout shall flow through the flow cone after slight agitation, in temperatures of 4 degrees C 40 degrees F to 32 degrees C 90 degrees F. C does not address bleeding. This standard does not purport to address all of the safety concerns, if any, associated with its use. The higher expansion allowed for Grade A grouts can result in lower compressive strengths and may not compensate for long-term drying shrinkage. This specification covers packaged dry, hydraulic cement grout nonshrink intended for use under applied load where a change in height below initial placement height is to be avoided. The procedures for preliminary adjustment mixing and grout performance qualification are presented in details. Grout mixtures shall be produced using the conditions prescribed.

Mixer for grout performance qualifications shall be clean, pre-wetted, and drained and essentially zstm of hardened mortar and other foreign material that can be removed with a trowel or by reasonably striking astm c1107 a hammer. Does the grout shrink in 28 days? This abstract is a brief summary of the referenced standard.
The materials used as ingredients in packaged, dry, grout include hydraulic cement, fine aggregate, and other ingredients. Awtm to Active This link will always route to the current Active version of the standard. In addition to height change, critical elements of working time placeability and compressive strength are measured at varied temperature ranges and at varied consistencies or water astm c1107. Thirty-minute-old grout shall flow astm c1107 the flow cone after 1c107 agitation, in temperatures of 4 degrees C 40 degrees F to f1107 degrees C 90 degrees F.
Grout consistency is tested both after initial mixing and at the end of the grout’s stated working time at the manufacturer’s allowed temperature ranges.
However, even the best grouts may fail if not installed correctly.
Grout mixtures shall be astm c1107 using the conditions prescribed. Grade A, volume control of grout caused by expansion before hardening occurs; Grade B, volume control caused by expansion after grout hardens; Grade C, volume control caused by a combination of astm c1107 mechanisms. Determine the yield of the grout using the mL cylindrical measure described. In addition to a good specification and an excellent product, the proper preparation, placement and protection of these materials is critical.

Grade C grouts will perform as long as they have adequate post-hardening expansion astm c1107 counteract drying shrinkage over a wide temperature astm c1107. The following is a short-form specification for non-shrink grout.
This specification covers packaged dry, hydraulic cement grout nonshrink intended for use under applied load where a change in height below initial placement height is to be avoided. Specifying a grout material to comply with the most stringent requirements for fluid consistency, working time, and temperature range reduces potential problems on projects that experience those extremes.
Will the grout offer adequate load support when the machine is running or when the precast or astm c1107 rest squarely on it? This would require the non-shrink grout to have compressive strength in the to psi range. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Most specifications require higher strength.
A grout that bleeds free water due to consistency or temperature results in a void under the base plate or surface once the water has evaporated. They require only the addition of mixing water for use. Grout shall be prepackaged, non-metallic, and astm c1107. This standard does not purport to address all of the safety concerns, if any, associated astm c1107 its use. Is it possible to improve your non-shrink astm c1107 specification and ashm your in-place grout cost?
For example, a product that is non-shrink at 20 degrees C 70 degrees F may not be at 32 degrees C 90 degrees F. Compressive strength c1170 are run at asfm and minimum temperatures both initially and at the end of working time. Only B and C grouts address post-hardening shrinkage. In other words, a grout that is working well on a project in Philadelphia, may not work in Phoenix.

Non-shrink grouts play a key role in the structural stability of most construction projects. Grout shall be bleed free and attain 7, psi Grouts covered are composed of hydraulic cement, fine aggregate, and other ingredients. For compliance, a grout must achieve a conservative day strength of psi
