Acid Resistance Testing

In extensive testing, a test cylinder made with Dynastone® technology is tested alongside an identically sized test cylinder made with traditional Portland mix. Each was submerged in a 1.0 pH acid bath for thirty 24-hour soak cycles. Between each cycle, each unit was scrubbed to remove any gypsum coating that may had developed as a result of corrosion and each bath was replenished to a 1.0 pH level. The results:

Acid Resistance Testing Weight Loss- 1 pH
Cycles	Traditional Portland	Dynastone®
30	15-30%	1-3%

See the results in high resolution:

• Dynastone® vs Concrete at 20 cycles x 1

• Dynastone® vs Concrete at 20 cycles x 2

• Dynastone® vs Concrete at 20 cycles x 3

• Dynastone® vs Concrete at 20 cycles x 4

Compressive Strength

The reaction that occurs with the Dynastone® technology is not a normal pozzolanic reaction. The initial strength gain is a result of the hydration of cement and water. Later age strength is attributed to the pozzolanic reaction, however, the strengths continue to increase surpassing that seen in normal fly ash concrete. This is due in part to the Dynastone® activator.

Time	Target Minimum Strengths	Dynastone®
12 hours	1500 psi	2000 psi
1 day	1800 psi	2000-3500 psi
28 days	5000 psi	5000-6000 psi
56 days	5000 psi	6000-8000+ psi
