Abstract

The setting of cement is adversely affected by soluble borates. To reduce interference, the extent to which borate can be insolubilized has been investigated. One specific mechanism of insolubilization is by inclusion into ettringite. Ettringite, Ca6Al2(SO4 )3(OH)12.26H2O, is a normal and stable constituent of Portland cement. It has an open but non-zeolite framework. Borate can substitute partially or fully for sulfate. It is concluded that ettringite has potential to reduce the solubility of borate.
