Abstract
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.
Claims21
A method of making a hardened water-resistant photoluminescent composition, the method comprising:
- providing a dry premixed photoluminescent composition, the premixed photoluminescent composition comprising solid aggregates, a photoluminescent particulate component adapted to emit light when photoexcited, and a water-activated binder;
- and
- contacting the dry premixed photoluminescent composition with water to activate conversion of the water-activated binder, via diffusion of water, into a water-resistant binder matrix having a transparency allowing transmission of at least a portion of the light emitted by the photoluminescent particulate component, thereby forming the hardened water-resistant photoluminescent composition;
- wherein the binder is made of particles having a particle size ranging from 75 μm to 9.50 mm.
A method of making a hardened water-resistant photoluminescent composition, the method comprising:
- providing a dry premixed photoluminescent composition, the premixed photoluminescent composition comprising solid aggregates, a photoluminescent particulate component adapted to emit light when photoexcited, a water-activated binder, and one or more additives being at least one of an anti-leaching agent, a hydrophilic agent, a pH-control agent, a water-resistance agent, and a dust control agent;
- and
- contacting the dry premixed photoluminescent composition with water to activate conversion of the water-activated binder, via diffusion of water, into a water-resistant binder matrix having a transparency allowing transmission of at least a portion of the light emitted by the photoluminescent particulate component, thereby forming the hardened water-resistant photoluminescent composition.
A dry premixed photoluminescent composition for forming joints between pavers or stones, the dry premixed photoluminescent composition comprising solid aggregates, a photoluminescent particulate component adapted to emit light when photoexcited, and a water-activated binder being made of particles having a particle size ranging from 75 μm to 9.50 mm and being activable upon contact with water to produce a hardened photoluminescent composition for forming the joints.
