Cementaid Rapidard - High Early Strength Admixture

Waterproofing and Admixtures

RAPIDARD

High Early Strength and Set Accelerating Admixture

EFFECTS:

Produces normal concrete strength in reduced times as follows:

Qty. used per 40 kg bag	Normal 7 days strength at:	Normal 28 days strength at:
3/4 litres 1 litre 1.5 litres 2 litres	4 days 3-4 days 3 days 2 days	12-14 days 8-10 days 7-8 days 6-7 days

(Approx. results only - brand cements vary somewhat.)

Rapidard contains special high-early-strength components, plus Calcium chloride, plus anti-corrosion factors. Rapidard increases workability considerably, and the mix may be adjusted to take advantage of this, by reducing water content about 1 litre for each litre of Rapidard used.

SETTING TIME:

Rapidard has only a limited effect on initial setting time, being designed for adequate time for working and placing, and yet accelerate strength gain after setting. At 1 litre/bag, setting time will be reduced by about 30% at 2 litres, by about 50%. If required, this can be corrected by use of PLASTET No. 2 for set retardation.
When used in place of water the Rapidard causes cement to harden in minutes.

WHERE RECOMMENDED:

For early stripping of formwork, early use of concrete structures, increased mold turnover for pre-cast units. Also for large concrete floor pours, to allow finishing to closely follow placing..

CAUTION:

NOTE: Rapidard contains calcium chloride and is not recommended for prestressed concrete or reinforced concrete exposed to moisture or dampness. (See SUPERPLASTET F)

SPECIFICATIONS
