Abstract
Lithium-treated calcium aluminate cement (CAC)-based products, concretes, and related techniques are disclosed. In accordance with some embodiments, a lithium-treated CAC mixture may be produced by intergrinding ground-down CAC, class C fly ash, a lithium compound, and a polycarboxylate material. In accordance with some embodiments, a cementitious material may be produced by intergrinding said lithium-treated CAC mixture with class C fly ash, sodium citrate, and a polycarboxylate material. In accordance with some embodiments, a concrete may be produced by mixing said cementitious material (including said lithium-treated CAC mixture) with rock, sand, and water.
Claims29
A method comprising:
- producing a cementitious material comprising:
- a calcium aluminate cement (CAC)-based mixture comprising:
- calcium aluminate cement (CAC);
- a first amount of class C fly ash;
- a lithium compound;
- and
- a first polycarboxylate material;
- a second amount of class C fly ash;
- sodium citrate;
- and
- a second polycarboxylate material.
A method comprising:
- producing a calcium aluminate cement (CAC)-based mixture comprising:
- calcium aluminate cement (CAC);
- a first amount of class C fly ash;
- a lithium compound;
- and
- a first polycarboxylate material;
- wherein producing the CAC-based mixture involves intergrinding the CAC, the first amount of class C fly ash, the lithium compound, and the first polycarboxylate material;
- and
- wherein at least one of:
- the intergrinding is performed for about 30 minutes±10 minutes;
- the intergrinding is performed until a D90 particle size distribution in the range of about 30-40 μm is achieved for the CAC-based mixture;
- and
- the intergrinding is performed utilizing a triethanol amine (TEA) grinding aid.
