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 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.
Claims20
A curable mixture configured to set in the presence of water, the mixture comprising:
- magnesium oxide;
- and
- at least one first accelerant, wherein the at least one first accelerant comprises magnesium chloride in the form of MgCl2.6H2O or magnesium nitrate in the form of Mg(NO3)2.6H2O;
- at least one second accelerant, the at least one second accelerant is different than the at least one first accelerant, wherein a proportion by weight of the at least one second accelerant is equal to or less than 2% of a proportion of magnesium oxide by weight of the mixture;
- wherein a proportion by weight of MgCl2.6H2O or Mg(NO3)2.6H2O is 80% to 120% of the proportion of magnesium oxide 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 6000 psi;
- and
- wherein the 1-day strength of the mixture once combined with water and permitted to cure is at least 4000 psi.
