How thick can you pour non-shrink grout?
Minimum application thickness is 1” (25 mm) and a maximum thickness of 4” (100 mm).
What is Class C grout?
Class C grouts: (also known as Performance Grouts) are shrinkage compensated (non-shrink) during both the plastic and post hardened state.
What is ASTM C476?
ASTM C476 defines two types of grout: fine and coarse. Fine grout contains sand smaller than ⅜ in. (9.5 mm) as its only aggregate, while coarse grout allows pea gravel smaller than ½ in. These requirements prescribe minimum and maximum aggregate sizes and a minimum grout compressive strength of 2,000 psi (13.79 MPa).
Will non shrink grout crack?
Cement based repair mortars, non-shrink grouts or concretes may form fine plastic shrinkage cracks when exposed to hot weather conditions. Cementitious repair mortars and non-shrink grouts have a minimum and maximum application temperatures as well as material temperature requirements.
What is considered non shrink grout?
Non-shrink grout is a hydraulic cement grout that, when hardened under stipulated test conditions, does not shrink, so its final volume is greater than or equal to the original installed volume. It is often used as a transfer medium between load-bearing members.
Where can I use non shrink grout?
NSPG is used when setting machinery bases, generators, mills, presses, compressors, etc., structural grouting of precast columns, steel columns, and anchoring of sign posts, anchor bolts, and dowels. It is essentially a structural filler in these applications.
How long does it take for non shrink grout to dry?
A damp cure of at least 1 day is necessary to control the non-shrink characteristics and maintain strength levels. When properly mixed to a fluid consistency, FastSet™ Non-Shrink Grout will fully comply with ASTM C1107 and retain a fluid consistency for 20 minutes at 70 degrees F (21 degrees C).
Why did my non shrink grout crack?
When the water content inside the cementitious material drops below 80% RH, then cement curing and hydration stops. Cracks typically occur within the first few hours after application due to rapid water loss from the surface quicker than it can be replenished by the bulk mix and can occur up to 72 hours later.
Which is the most common specification for non shrink grout?
ASTM C-1107 This is the most common specification covering three grades of non-shrink grout: Grade refers to the expansive mechanism Grade A Pre-Hardening Volume-Adjusting: Volume control of grout is caused by expansion before hardening occurs.
Which is ASTM standard for dry cement grout?
Active Standard ASTM C1107 / C1107M | Developed by Subcommittee: C09.43 Book of Standards Volume: 04.02 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.
How long to cure Quikrete fastset non shrink grout?
Place the grout quickly and continuous-ly using light rodding to eliminate air bubbles. CURING A damp cure of at least 1 day is necessary to control the non-shrink characteristics and maintain strength levels. WORKING TIME When properly mixed to a fluid consistency, QUIKRETE FastSet Non-Shrink Grout will fully
What do you need to know about hydraulic cement 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. Grouts covered are composed of hydraulic cement, fine aggregate, and other ingredients. They require only the addition of mixing water for use.
