Grout shall be prepackaged, non-metallic, and non-gaseous. Most specifications require higher strength. The procedures for preliminary adjustment mixing and grout performance qualification are presented in details. Grade C grouts will perform as long as they have adequate post-hardening expansion to counteract drying shrinkage over a wide temperature range. This option is mobile friendly and compatible with all devices, including mobile tablets and smart phones.
The higher expansion allowed for Grade A grouts can result in lower compressive strengths and may not compensate for long-term drying shrinkage.
Concrete News: ASTM C
Although C addresses grout limitations with respect to temperature, consistency, and working time, it fails to set limits for these parameters, allowing manufacturers to do so. 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 both mechanisms. Compressive strength tests are run at maximum and minimum temperatures both initially and at the end of working time.
The performance requirements of the specimens are presented in details. Mixer for grout performance qualifications shall be clean, pre-wetted, and drained and essentially free of hardened mortar and other foreign material that can be removed with a trowel or by reasonably striking with a hammer.

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.
In other words, a grout that is working well on a project in Philadelphia, may not work in Phoenix. 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 content.
A grout with very narrow limits may comply with Asgm, but such narrow parameters could result in failure. It is the c107 of the user of astmm standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
In addition to a good specification and an excellent product, the proper preparation, placement and protection of these materials is critical. The procedures for preliminary adjustment mixing and grout performance qualification are presented in details.
Certified independent test data required. Grouts covered are composed of hydraulic cement, fine aggregate, and other ingredients. For compliance, a grout must achieve a conservative day strength of psi The materials used as ingredients in packaged, dry, grout include hydraulic cement, fine aggregate, and other ingredients. 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.
Consistency testing shall be performed on the grout mixture. Their function is three fold: For smaller quantities of grout, the mortar-mixing apparatus shall be as specified. This abstract is a brief summary of the referenced standard.
Determine the yield of the grout using the mL cylindrical measure described.
Will the grout offer adequate load support when the machine is running or when the precast or columns rest squarely on it? Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Non-shrink grouts play a key role in the structural stability of most construction projects. Is it possible to improve your non-shrink grout specification and lower your in-place grout cost?
Grout consistency is tested both after initial mixing and at 1c107 end of the grout’s stated working time at the manufacturer’s allowed temperature ranges. C classifies grouts into three categories: Combining values from the two systems may result in non-conformance with the standard.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
