摘要 |
A binder composition for Portland cement is disclosed, said composition including 100 parts by weight metakaolin and, based upon said metakaolin, from 20 to 70 parts by weight slag; from 85 to 130 parts by weight of at least 1 material selected from the class consisting of fly ash, calcined shale, and calcined clay; from 70 to 215 parts by weight finely divided silica, preferably amorphous silica; and from 55 to 145 parts by weight of a mixture of potassium silicate and potassium hydroxide, wherein at least 55 parts by weight is potassium silicate. The binder composition can be mixed with Portland cement or with a combination of Portland cement and fly ash to provide a composition curable to a material having a high early strength and a high ultimate strength.
