A method for manufacturing an engineered stone, the method including: providing a mixture comprising at least a stone or stone like material and a binder; compacting the mixture; curing the binder; and further comprising printing a printed pattern on at least a top surface of the engineered stone.

Bioinspired chemical additives, coating, and chemical solution useful for enhancing the strength of self-healing hydraulic-cement concrete, comprising of micro/nano/textured dual phobic dot domains, hydrogel polymer, water, mineral oil, and surfactants assembled into micelle emulsion, mixed with cement, water, sand, and aggregates by weight percentage at a mix ratio of from 0.00001/99.9999 to 10.0/90, of which the ratio of water to cement from 0.10 to 0.80 (W/C), the volume fraction of cement for total volume of concrete from 5 to 50%, sand 40% to 90%, and aggregate 40% to 90%, a replacement of cement with cementitious materials from 0.01% to 75%, having an early age of compressive strength over more than 4000 (PSI) within 24 hour, ultimate compressive strength >7500 (PSI) after exposed over one year, gaining a self-healing efficiency over 80(%), contributed to dispersive, hydrogen, ionic chelating interactions, and activated with self-assembling thiol/disulfide plant-based protein fibril's crosslinking bonds.

The present provides a concrete and mortar mix and composition thereof with poor quality sand such as desert sand, hydraulic binder (cement) and filamentous cellulose, where the desert sand/spherical sand replaces conventional concrete river sands. The present disclosure also relates a filamentous cellulose, such as, cellulose filaments (CF), cellulose nano filaments, cellulose nanofibrils (CNF) and microfibrillated cellulose (MFC) as a concrete/mortar and sand adhesion additive with hydraulic binder (cement), and to a method of making the concrete. This method also relates to a method to prevent the sliding of individual sand grains against one another and therefor similarly contributes to the stabilization of the building materials.

A method for producing photocatalytic mortar includes providing a mortar-producing material including a fine aggregate and cement, a reactant mixture including a zinc source and urea, and a microorganism-containing mixture including water and a urease-producing microorganism, subjecting the microorganism-containing mixture and the reactant mixture to microbial induced precipitation in the mortar-producing material, subjecting zinc carbonate crystal-containing mortar produced to curing for the same to undergo hydration, and subjecting cured mortar to hydrothermal synthesis, so that zinc carbonate crystals therein are converted to nano zinc oxide crystals.

A method of producing a glass briquette in which reclaimed glass fines are mixed with a binder material to create a mixture. The mixture is subsequently compressed in a chamber to form a briquette having the shape of the interior of the chamber. The reclaimed glass includes glass fines of a size of smaller than 10 mm. The method is performed without melting the glass fines such that the resulting briquette contains the discrete glass fines held in the binder and may be used as a furnace ingredient for later glass product production. The glass briquette may contain other batch ingredients required in the production of glass.
