An exemplary process for forming a cured hybrid magnesium cement composition may include first combining a mixture of magnesium-containing material, a metal silicate inorganic polymer having a repeat unit of SiP.sub.2O.sub.7, and a salt having a non-metallic oxide anion, and then mixing the mixture with water.

A hybrid magnesium cement composition formed from an A-side component and a B-side component. The A-side component includes an A1-component including a light-burn grade magnesium-containing material, and an A2-component including a non-metallic oxide salt. A B-side component having a metal silicate polymer is included.

A dry construction composition is easily wet-sprayable by means of a screw pump, thus forming, after hardening, a durably mechanically resistant insulating material (<0.1 W.Math.m1.Math.K1). The composition contains: A at least one binder, itself including: A1 at least one main binder containing lime and/or at least one alumina source and/or at least one calcium sulfate source, preferably at least one alumina source, A2 at least one water-retaining agent, and A3 preferably at least one surfactant; and B at least one biosourced filler, preferably of plant origin. The ratio B/A (liters/kg) is between 2 and 9. The composition is intended to be mixed with water in a water/binder ratio A of no lower than 0.8. Also disclosed is a wet composition, the preparation thereof, to the binder A taken in isolation, and to a method of spraying the composition onto a horizontal or vertical substrate or by molding.

A method for production of a modified cement powder comprises the steps of: a) acquiring batch cement, and b) forming a modified cement powder with an average particle size of between 2 nm and 150 nm. A method for improving the stability of a soil sample comprises a steps of: a) acquiring the soil sample, b) acquiring a cement, c) forming a cement powder (nano-cement) with an average particle size of between 2 nm and 150 nm, optionally preparing a suspension of the nano-cement in water, d) mixing the cement powder or the suspension of the cement powder in water with the soil sample in a weight ratio of between 1:100 and 1:1 of the cement powder to the soil sample, respectively, e) applying the mixture obtained in step d) to the required construction site, optionally by applying the PWS mixtureing, f) forming the mixture at the construction site in accordance with a predetermined construction project until a structure of predetermined dimensions is obtained, g) exposing the structure obtained in step f) to an amount of water for the curing time.

A cured hybrid magnesium cement (HMC) composition and an exemplary process for forming a cured HMC composition are disclosed. The cured HMC composition includes a magnesium-containing material, a metal silicate inorganic polymer having a repeat unit of SiP.sub.2O.sub.7, and a salt having a non-metallic oxide anion. The process includes first combining a mixture of magnesium-containing material, a metal silicate inorganic polymer having a repeat unit of SiP.sub.2O.sub.7, and a salt having a non-metallic oxide anion, and then mixing the mixture with water.

Disclosed herein are fire resistant compositions and articles, for example, in the form of boards, insulation, sheeting, blocks, panels and similar materials of construction. Also disclosed are methods of preparing fire resistant compositions and articles and methods of use thereof.

A system and method for applying a construction material is provided. The method may include mixing blast furnace slag material, geopolymer material, alkali-based powder, and sand at a batching and mixing device to generate a non-Portland cement-based material. The method may also include transporting the non-Portland cement-based material from the mixing device, through a conduit to a nozzle and combining the transported non-Portland cement-based material with liquid at the nozzle to generate a partially liquefied non-Portland cement-based material. The method may further include pneumatically applying the partially liquefied non-Portland cement-based material to a surface.
