Concrete News: ASTM C
The materials used asgm ingredients in packaged, dry, grout include hydraulic cement, fine aggregate, and other ingredients. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Does the grout shrink in 28 days? Work Item s – proposed revisions of this standard. They require only the addition of mixing water for use.
ASTM-C was initially introduced to the public asmt C does not address bleeding. The materials used as ingredients in packaged, dry, grout include hydraulic cement, fine aggregate, and other ingredients. Compressive strength tests are run at maximum and minimum temperatures both initially and at the end of working time. Will the grout offer adequate load support when c107 machine is running or when the precast or columns rest squarely on it? Grade C grouts will perform as long as they have c117 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. 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.
The grout is tested at the manufacturer’s maximum allowed water-to-dry solids ratio and is rated as plastic, flowable, or fluid. Grout shall be prepackaged, non-metallic, and non-gaseous. 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.
In addition to a good specification and an excellent product, the proper preparation, placement and protection of these materials is critical.
They require only the addition of mixing water for use. 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. 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.
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. Their function is three fold: 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.
Use on a local area network or other network is not permitted.
For compliance, a grout must achieve a conservative day strength of psi Only B and C grouts address post-hardening shrinkage. 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.
Determine the yield of the grout using the mL cylindrical measure described. The performance requirements of the specimens are presented xstm details. Non-shrink grouts play a key role in the structural stability of most construction projects. Most specifications require higher strength.
Certified independent test data required.
This would require the non-shrink grout to have compressive strength in the to psi range.
