| PRODUCT HISTORY | | In 1970, TAIHEIYO MATERIALS CORPORATION has developed the EXPAN products.
EXPAN consists of free calcium oxide as the major component, calcium silicate and interstitial material and its expansion is due to the crystal growth of Ca(OH)2 delivered by hydration of CaO.

- EXPAN-S
Used for manifacture of high strength concrete products, such as hume pipes, box culverts, etc., utilizing chemical pre-stress introduced by its restrained expansion againts re-bars.
- EXPAN-M
Used for crack reduction of massive concrete structures, with which usually cracks due to drying shrinkage and those due to heat hydration are seriourly concerned.
|
| BENEFITS | | Crack Reduction
Crack due to drying shrinkage of concrete, which is an inherent drawback of cement, can be reduced by mixing cement with an appropriate amoutn of EXPAN because its expansion effectively conpensates for the drying shrinkage.
