LOW-ALKALI FLY ASH CEMENT AND METHOD OF MAKING |
摘要 |
A method for making a low-alkali fly ash cement includes forming a mixture of class C fly ash and an aqueous solution and forming low-alkali fly ash cement from the mixture. The aqueous solution has an alkali at a molar concentration between about 0.002 M and about 2 M. A low-alkali fly ash cement includes class C fly ash and an alkali activating agent. The low-alkali fly ash cement contains between about 3×10−4 wt % alkali activating agent and about 2 wt % alkali activating agent. A method for making fly ash cement includes forming a mixture of class C fly ash and water, wet pressing the mixture and forming fly ash cement from the mixture by curing the mixture at a temperature between about 60° C. and about 90° C. |
