Methods for engineered cellular magmatic geotechnical fill and articles thereof are disclosed. For example, the magmatics may include one or more infiltration materials that are configured not to sinter when a foamed mass is formed. The infiltration materials may be enclosed in cells of the foamed mass and may be floating and/or fixed to the cell walls.

Described are dry cast lightweight veneer blocks and a system and method of installing lightweight veneer blocks. The courses can be assembled without mortar between the courses. As an example, sides of the veneer blocks have areas that recede from an imaginary plane between adjacent veneer blocks to give a deep texturing and a shadow effect between veneer blocks. The installation system and method include a substrate, an air barrier applied to the substrate, a plurality of veneer blocks, and an adhesive applied between the plurality of veneer blocks and the air barrier.

The present invention discloses a novel, improved, simple and economic process for manufacturing lightweight ceramic sand. The lightweight ceramic sand is produced from the industrial wastes, wherein the major raw materials are fly ash, bauxite residue and biomass-coal fly ash. The present invention relates to the production of new fine particulates at high throughput and at low manufacturing cost to provide an alternative or substitute to the fast-depleting natural sand including crushed stones and lightweight fine aggregates produced from expanded clay, expanded glass and volcanic activities. Lightweight ceramic sand of the present invention can be used as a building and construction material and foundry sand.

To provide a prestressed concrete which can be used for non-primary structural members such as general building members by using a chemical stress induced by an expansive material and a mechanical stress induced by a rust-resistant wire together and achieving reduction in weight and suppression of cracking. A prestressed concrete for non-primary structural members is characterized in that a mechanical stress induced by a tensional material and a chemical stress induced by an expansive material for a concrete are introduced and that the tensional material is a rust-resistant continuous fiber reinforcing wire.

The invention discloses high-strength glass-ceramic-based lightweight aggregates and the preparation method thereof. The mass ratio of raw material components is 50-70 parts of engineering muck, 20-40 parts of glass, 3-7 parts of calcium carbonate, 3-7 parts of magnesium oxide, and 2-10 parts of a nucleating agent; the nucleating agent is at least one of calcium fluoride, titanium dioxide, and chromium oxide. After crushing, mixing, and granulating, spherical particles with a particle size of 10-12 mm are formed; and then the product can be obtained after drying, sintering, and cooling. The obtained lightweight aggregate from the invention has a diopside matrix which provides high strength and a low water absorption rate at low densities. Moreover, waste glass and engineering muck could be utilized with high value.

A method of agglomerating bulk ceramic fibers includes mixing the bulk ceramic fibers with water to form wet fibers; mixing the wet fibers with a binder including an organic binder and/or an inorganic binder to form agglomerates; and drying the agglomerates. The agglomerates may be mixed with additional binders and fillers to form an insulating mix that may be used to insulate a furnace or other heat source. A foaming nozzle may be used for the application of agglomerates. A foaming agent and water are air atomized within the foaming nozzle and the resulting foam is mixed into pneumatically conveyed agglomerates, which result results in a lightweight refractory material layer on a target substrate.
