A method of making a chemical-resistant concrete composition, namely a quartz-based casting composition, is provided. The quartz-based casting composition provides excellent resistance to attack by chemicals, including weak and strong acids. The quartz-based casting composition is useful as concrete in various construction applications where corrosion resistance is needed. The casting composition includes a dry component and a wet component. The dry component includes about 25% to about 100% by weight quartz and the corrosion resistance increases with increasing quartz content.

Thermoset ceramic compositions and a method of preparation of such compositions. The compositions are advanced organic/inorganic hybrid composite polymer ceramic alloys. The material combines strength, hardness and high temperature performance of technical ceramics with the strength, ductility, thermal shock resistance, density, and easy processing of the polymer. Consisting of a branched backbone of silicon, and alumina, with highly coordinated Si—O—Si or Al—O—Al bonds, the material undergoes sintering at 7 to 300 centigrade for 2 to 94 hours from water at a pH between 0 to 14, humidity of 0 to 100%, with or without vaporous solvents.

Methods for the production of ceramic composites in which three-dimensional (3D) printed organic polymer fibers are embedded in an amorphous inorganic ceramic matrix are provided. The composites are made by electrospinning the organic polymer fibers and collecting them in a liquid or gel collector. Ceramic precursors added to the liquid collector after the fibers are collected, or present in the gel collector during the electrospinning, are then cured to form a solid ceramic matrix around the organic polymer fibers to produce an organic polymer fiber-reinforced ceramic.

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.
