Claim 13:
14. A method of manufacturing a magnesium oxide cement, the method comprising:
dissolving magnesium chloride in water to form a brine solution;
dissolving MgO endothermically in the solution to form a cement mixture;
adding aggregate to the solution;
mixing the cement mixture; and
curing the cement mixture in a mould,
wherein the molar ratio of MgO:MgCl2:H2O is 5-9:1:10-20;
wherein the MgO comprises a first and second plurality of MgO particles, wherein the first plurality of particles has a surface area of at least 70 m2/g, and wherein the second plurality of particles has a surface area at least 40 m2/g lower than the first plurality of particles.
