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.

A solid cement construction panel includes an interior core filling sandwiched between two exterior faces to form a composite panel. The interior core filling is constructed to have a high strength cement, EPS (expanded polystyrene) foam, fly ash, sand particles and water, wherein the interior core filling has properties of heat preservation and soundproof. Each of the exterior faces is made of fiber reinforced material having properties of light weight, heat insulation, fireproof, and waterproof and moisture-proof.

A structural material composition comprises: a geopolymer matrix, the geopolymer matrix formed from an alumina silicate source and an alkaline activator; and an antibacterial agent (e.g. biocide and/or heavy-metal based antibacterial agent) encapsulated in an antibacterial agent carrier to form a first plurality of encapsulated antibacterial agent particles. The first plurality of encapsulated antibacterial agent particles is integrated with the geopolymer matrix during polymerization.
