Methods and compositions for the installation of scientifically engineered and constructed unpaved runways are disclosed herein. The compositions are heterogeneous mixtures produced by blending aliphatic or cyclic organic compounds with binders that chemically react with gravel, aggregate, and soil particles to create permanent bonds, resulting in a strengthened and stabilized surface. When blended into the aggregate of a runway surface, the organic compounds act as a carrier fluid, distributing the binder system evenly so particles of all sizes are thoroughly and uniformly coated with the composition. Once the composition is distributed, an adhesion promoting compound reacts with constituents in the aggregate to increase the formation and strength of chemical bonds between particles.

A polymer-based compound, useful as a polymer masonry unit is disclosed that can include a polymer added to a quarry byproduct to manufacture a quality brick unit. The present disclosure solves the technological problem of providing a structurally sound brick or concrete alternative without the need for kiln firing, using traditionally unusable waste material. By combining quarry byproduct and a polymer, a polymer masonry unit can be fabricated having compressive strength and architectural utility. In one exemplary embodiment, fiber elements can be added to the byproduct and polymer mixture to increase structural stability. The present disclosure improves the performance of the system itself by providing a basic block or brick unit using an environmentally responsible manufacturing process that reduces cost and waste. The manufacturing process includes a polymer/base material that can be poured into molds that cures over a predetermined period, without the need for kiln firing.

An organic-inorganic composite including: a plurality of anisotropic ceramic particles having different aspect ratios; a resin that is combined with the ceramic particles; and a plurality of projections projecting out from the surface of the ceramic particles, thereby increasing the shear resistance of the interface between the ceramic particles and the resin. At least some of the ceramic particles neighboring each other are closely arranged such that the projections partially contact each other, thereby increasing the shear resistance between the ceramic particles due to the contacting ceramic particles.

A premixed photoluminescent composition and related hardened form and method of forming joints for pavers or stones. The premixed photoluminescent composition comprises solid aggregates; a photoluminescent particulate component adapted to emit light when photoexcited; and a binder. When in contact with an activator, oxygen or water, the binder is adapted to harden into a water-resistant binder matrix that bonds the solid aggregates and embeds the photoluminescent particulate component. In use, the water-resistant binder matrix has a transparency allowing transmission of at least a portion of the light emitted by the photoluminescent particulate component.

A crosslinkable polymer powder compositions redispersible in water includes one or more vinyl ester polymers, one or more compounds bearing epoxide groups and optionally one or more curing agents which crosslink with the compounds bearing epoxide groups. The vinyl ester polymers do not comprise any epoxide-functional monomer units. The crosslinkable polymer powder compositions redispersible in water includes ≥51% by weight, based on the total weight of the vinyl ester polymers, of one or more compounds bearing epoxide groups.
