Engineering Classifications and Comparisons
Unconfirmed Compression Test
- Two samples prepared... one cured for 7 days and one cured for 14 days.
- 7-day Compressive Strength=79 psi
- 14-day Compressive Strength = 166 psi
- 47% Increase
- Indicates the CaSO4 tends to gain strength with time.
- Due to crystallization & cementation, CaSO4 tends to form self-bonding aggregates.

Summary
CaSO4 ~ 1.6 Ton/CY vs. Limestone ~ 1.375-1.9 Ton/CY
GS-100 is 10-15% Lighter than Limestone > More Volume for Less Weight!
GS-100 is Higher Load Bearing > 1" of GS-100 ~ 1.5" of Limestone!!
GS-100 is Less Expensive than Limestone > $$ Savings!!
