ASTM C 779 - DEPTH OF WEAR.
Abrasion resistance - Revolving disks. 32.5% improvement at 30 minutes.
ASTM D 3359 - SURFACE ADHESION
Adhesion of epoxy coatings is 22% higher over untreated samples. No change in adhesion for polyurethane.
Moisture loss during the critical, initial 24 hour period was determined on treated and untreated samples in a controlled environment cabinet. Untreated samples registered a 93% greater moisture loss over Ashford Formula treated samples.
ASTM C39 - COMPRESSIVE STRENGTH
After 7 days, an Ashford Formula treated sample had an increase of 40% more compressive strength than untreated samples.
After 28 days, it had a 38% increase over untreated samples.
ASTM C 805 - REBOUND NUMBER
Impact resistance by Schmidt hammer resulted in an incrase of 13.3% for an Ashford Formula treated sample versus untreated samples.
Using a 7-foot (2.13 m) head of water on a 4.91 square inch (124.71 mm) area treated with the Ashford Formula, the treated sample only allowed a seepage rate of 0.00073 oz (0.022 cc) per hour. After several days, the treated sample became damp, but no local seepage was observed.
ASTM C-1028 - FRICTION
Samples treated with the Ashford Formula were found to be far less slippery than untreated samples. The coefficient of friction on steel-troweled samples treated with the Ashford Formula versus the reference tile were (a higher ratio represents a reduction in slippage):
Dry - 0.86 vs. 0.71
Wet - 0.69 vs. 0.47
ASTM G 23 - LIGHT EXPOSURE DEGRADATION
Exposure to ultraviolet light and water yielded no evidence of adverse effects on samples treated with the Ashford Formula.

At least 93% greater moisture retention during the initial 24 hour curing period compared to untreated samples
Four Key Enhancements that the Ashford Formula does for concrete,
Three of them take place within hours or days: hardening, dustproofing, and curing. Only sealing requires significantly more time. While the sealing process is well advanced at about 90 days, allowing water to begin to bead on a smooth steel troweled surface, the concrete will continue its sealing process at a much slower rate for up to 9-12 months.

Burnished Concrete Floor:
Apply product immediately following the finishing operation, as soon as the surface is firm enough to walk on and before hairline checking and temperature cracking begin. Curecrete recommends application using a low pressure, high-volume pump that will dispense material at 40 - 70 psi (276 - 483 kPa) and roughly 3 - 5 gal (11 - 19 L) per minute. Keep the entire surface wet with Ashford Formula for 30 minutes, working it into the concrete surface with a soft-bristled broom. As the Ashford Formula becomes slippery underfoot, lightly mist the surface with water. As it again becomes slippery underfoot, thoroughly flush the entire surface with water and squeegee it completely dry to remove all surface alkali and/or Ashford Formula residue.
Exterior/Broom Finished Concrete Floor:
On exterior broom-finished surfaces, no flushing is required, but any remaining Ashford Formula must be squeegeed or broom-swept from the surface after 30 - 40 minutes.
