New product S-630
CAPSTONE S-630
S-630 is the newest product launched in 2012. Its strength has reached 9000psi unbeatably. It shows the highest technique of capping gypsum at present all over the world and the R&D ability of TAIWAN CAPSTONE Lab.
The holding time is slightly longer than any other products at 40 mins. It fits the highest strength concrete compressive test.

According to C617/AASHTO T231 5.1.1:
- The average strength of 15 cylinders capped with the materials is not less than 98 percent of the average strength of 15 companion cylinders capped with neat cement paste or 15 cylinders ground plane to within 0.002 in (0.05 mm). The test result of average strength is 1.038. It passes C617/AASHTO T231 5.1.1.
- The standard deviation of the strengths of the capped cylinders is not greater than 1.57, the test result is 1.012. It passes C617/AASHTO T231 5.1.1.
