Consol Expander As

This technical data sheet provides information on CONSOL EXPANDER AS, an expanding grout admixture for mortar and concrete. It is supplied as a powder and contains a water-reducing agent to increase workability while reducing the water content. It produces microbubbles that cause wet volume expansion and fluidity without segregation. The document lists recommended uses, benefits, instructions for use including mixing and application, and precautions. Dosage is typically 0.45-1% with 0.45% recommended for paste grouting. It has a shelf life of 1 year in dry storage and trial mixes are needed to determine the optimal water-cement ratio and dosage.

CONSOL EXPANDER AS
Expanding Grout Admixture (For Mortar and Concrete)

DESCRIPTION TECHNICAL DATA


CONSOL EXPANDER AS is a plasticized expanding grout Dosage
admixture is supplied as a powder. This product is an 0.45% - 1 %
expansion system which compensates for plastic shrinkage (note: when excess dosage have been used, please

contains a water-reducing agent which increases the
workability of the mix with a reduced water content. result)
Applications include bed grouting, duct grouting, non-shrink
infilling and jointing. By introducing micro bubbles into the Typical Dosage
mix, it produces wet volume expansion and increased 0.45% for pasta grouting

INSTRUCTION FOR USE


Mixing
For pre-stressed concrete work, a mixing time of 3 minute
with a w/c ratio up to 0.45. A mechanically powered grout
mixer must be used. For quantities up to 50 kg a slow speed
drill fitted with a CONSOL EXPANDER AS mixing paddle
is suitable. Larger quantities will require a high shear vane
mixer. It is essential that machine mixing capacity and
labour availability is adequate to enable the grouting
operation to be carried out continuously. This may require
the use of a holding tank with provision for gentle agitation
to maintain fluidity. The selected water content should be
accurately measured into the mixer. Slowly add the cement
and CONSOL EXPANDER AS. Mix continuously for 5
minutes, making sure that a smooth even consistency is
obtained.

Application
Areas to be grouted should be prepared to ensure
substrates are clean, sound, and then pre-wetted. The
unrestrained surface area of the grout must kept to a
minimum. Place the grout within 20 minutes of mixing to
gain the full benefit of the expansion process. Adopt usual
placing or pumping procedures ensuring a continuous
operation.

PRECAUTIONS
• Avoid contact with skin and eyes
• Wear protective gloves and eye protection during work
• If skin contact occurs, wash skin thoroughly.
• If in eyes, hold eyes open, flood with warm water and seek medical
attention without delay.
