Abstract
According to some embodiments, a curable mixture configured to set in the presence of water, wherein the mixture comprises magnesium oxide, a primary cementitious component (e.g., slag cement) and at least one accelerant. A proportion by weight of the primary cementitious component is 80% to 120% of a proportion of magnesium oxide by weight.
Claims29
A curable mixture configured to set in the presence of water, the mixture comprising:
- magnesium oxide;
- and
- a primary cementitious component, wherein the primary cementitious component comprises slag;
- and
- at least one accelerant, wherein the at least one accelerant comprises at least one of the following:
- magnesium chloride, magnesium nitrate, and magnesium sulfate;
- wherein a proportion by weight of the primary cementitious component is 80% to 120% of a proportion of magnesium oxide by weight of the mixture;
- wherein a sum of the proportions of magnesium oxide and the primary cementitious component comprises at least 15% by weight of the mixture;
- wherein the mixture does not include Portland cement or gypsum;
- wherein the 7-day strength of the mixture once combined with water and permitted to cure is at least 2000 psi;
- and
- wherein the 1-day strength of the mixture once combined with water and permitted to cure is at least 1000 psi.
