Historical Version s – view aetm versions of standard. A good rule of thumb is an over design factor of 1. Certified independent test data required.
Is it possible to improve your non-shrink grout specification and lower your in-place grout cost? In addition to a good specification and an excellent product, the proper preparation, placement and protection of these materials is critical. This standard does not purport to address all of the safety concerns, if any, associated with its use. ASTM-C was initially introduced to the public in All trademarks shown are the intellectual properties of their respective owners.
They require only the addition of mixing water for use. However, even the best grouts may aatm if not installed correctly.
Grouts covered are composed of hydraulic cement, fine aggregate, and other ingredients.
Concrete News: ASTM C
This would require the non-shrink grout to have compressive strength in the to psi range. Work Item s – proposed revisions of this standard. 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. For compliance, a grout must achieve a conservative day strength of psi Determine the yield of the grout using the mL cylindrical measure described. Most specifications require higher strength. Grade C grouts will perform as long as they have adequate post-hardening expansion to counteract drying shrinkage over a wide temperature range.
Grout mixtures shall be produced using the conditions prescribed. Although C addresses grout limitations with respect to temperature, consistency, and working time, it fails to set limits for axtm parameters, allowing manufacturers to do so.
Does the grout shrink in 28 days? 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. Grout shall be prepackaged, non-metallic, and non-gaseous. This abstract is a brief summary of the referenced standard. C does not address bleeding.
ASTM C-1107
Non-shrink grouts play a key role in the structural stability of most construction projects. Grout mixtures shall be produced using the conditions prescribed.
For smaller quantities of grout, the mortar-mixing apparatus shall be as specified. Grout shall be bleed free and attain 7, psi Determine the yield of the grout using the mL cylindrical measure described.
In addition asm height change, critical elements of working time placeability and compressive strength are measured at varied temperature ranges and at varied consistencies or water content. Mixer for grout performance qualifications shall be clean, pre-wetted, and drained and essentially free of hardened mortar and other foreign material that asstm be removed with a trowel or by reasonably striking with a hammer.
Grouts covered are composed of hydraulic wstm, fine aggregate, and other ingredients. In other words, a grout that is working well on a project in Philadelphia, may not work in Phoenix.
The grout is tested at the manufacturer’s maximum allowed water-to-dry solids ratio and is rated as plastic, flowable, or fluid. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Only C11107 and C grouts address post-hardening shrinkage. They require only the addition of mixing water for use. JavaScript seems to be disabled in your browser.
