EARLY HIGH-STRENGTH MINERAL POLYMER

An early high-strength concrete composition is formed of a polysialatesiloxo material obtained by adding groundblast furnace slag to a reactant mixture consisting of alumino-silicate oxide (Si2O5, A1202) with the aluminum cation in a four-fold coordination, strong alkalis such as sodium hydroxide an...

Beschreibung
Zusammenfassung:	An early high-strength concrete composition is formed of a polysialatesiloxo material obtained by adding groundblast furnace slag to a reactant mixture consisting of alumino-silicate oxide (Si2O5, A1202) with the aluminum cation in a four-fold coordination, strong alkalis such as sodium hydroxide and/ or potassium hydroxide, water, and a sodium/potassium polysilicate solution. The slag may be added in an amount of 15 to 26 parts, by weight, based upon the reactant mixture. Sufficient hardening for demolding is obtained in about 1 hour with this composition.
