Why Gypsum Capping TAIWAN CAPSTONE

Around 30 mins, the strength of the gypsum can reach 5,000~9,000 psi (350~630 kgf/cm2). This type of gypsum is mostly used in the capping material for concrete compression test according to ASTM C617 standard, so our high strength Capping Gypsum the offer the convenient and excellent testing material for civil engineering industry.

What methods of capping are recommended for

Unbonded caps are not permitted for strengths exceeding 80 MPa (11,500 psi), because there are insufficient data on their performance with concrete stronger than 80 MPa (11,500 psi). High-strength gypsum cement and neat portland cement capping materials are generally acceptable as capping materials, but rarely used.
