LOW EFFLORESCENCE TILE GROUT COMPOSITION

摘要

The present invention provides a dry mix of cement, sand, metakaolin in the amount of 5 wt % or less, based on total solids in the dry mix, and aluminum cement in a low amount (≦1 wt. %, based on total solids in the dry mix) useful as a tile grout, as well as uses thereof and to methods of using the same as a tile grout. The dry mix when made into a mortar exhibits excellent resistance to efflorescence as a tile grout.
