The grout is tested at the manufacturer’s maximum allowed water-to-dry solids ratio and is rated as plastic, flowable, or fluid.
Their function is three fold: This would require the non-shrink grout to have compressive strength in the to psi range. Certified independent test data required.
Grade C grouts will perform as long as they have adequate post-hardening expansion to counteract drying shrinkage over a wide temperature range.
A grout with very narrow limits may comply with C, but such narrow parameters could result in failure. Is it possible to improve your non-shrink grout specification and lower your in-place grout cost? Link to Active This link will always route to the current Active version of the standard. Grout shall be bleed free and attain 7, psi Consistency testing shall be performed on the grout mixture. For compliance, a grout must achieve a conservative day strength of psi C does not address bleeding.
For example, a product that is non-shrink at 20 degrees C 70 degrees F may not be at 32 degrees C astj degrees F. Grout mixtures shall be produced using the conditions prescribed. Historical Version s – view previous versions of standard. Referenced Documents purchase separately The documents listed below are referenced within sstm subject standard but are not provided as part of the standard.
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. All trademarks shown are ast, intellectual properties of their respective asm. 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. Grout mixtures shall be produced using the conditions prescribed.
They require only the addition of mixing water for use. Combining values from the two systems may result in non-conformance with the standard.
The materials used as ingredients in packaged, dry, grout include hydraulic cement, fine aggregate, and other ingredients. Will the grout offer adequate load support when the machine is running or when the precast or columns rest squarely on it? Consistency testing shall be performed on the grout mixture. It has since undergone a few revisions and continues to be improved upon.
We recommend users of early versions of Internet Explorer to update to Version 10 or later. For smaller quantities of grout, the mortar-mixing apparatus shall be as specified. For smaller quantities wstm grout, the mortar-mixing apparatus shall be zstm specified.
The performance requirements of the specimens are presented in details. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Determine the yield of the grout using the mL cylindrical measure described.
Only B and C grouts address post-hardening shrinkage. 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.
Concrete News: ASTM C
This standard does not purport to address all of the safety concerns, if any, associated with its use. Grouts covered are composed of hydraulic cement, fine aggregate, and other ingredients.
However, even the best grouts may fail if not installed correctly.
