A lightweight veneer system and method for producing a construction material that simulates the appearance of natural finishes such as stone, brick, or exposed concrete while providing improved technical characteristics. The system incorporates a precise sequence of mixing water, acrylic polyester resin, recycled ground glass, calcium carbonate, fiberglass, and iron oxides for coloration, followed by the addition of white or gray cement and plaster. The specialized process involves treating molds with release agents and pigments to ensure natural-looking textures and colors. The material is then poured into molds, vibrated to remove air pockets, and cured in a controlled environment to achieve optimal hardness and moisture content. The final product is significantly lighter than conventional materials, offering advantages in transportation and installation. This environmentally conscious method includes recycling of both water and defective materials back into the production process, emphasizing sustainability alongside industrial efficiency.

A foam-forming composition for producing a rigid polyurethane foam including: (a) at least one isocyanate component; and (b) at least one isocyanate-reactive composition including: (bi) a rigid polyol compound; and (bii) a flexible polyol compound; (c) a catalyst package including at least one latent gelling catalyst; and (d) at least one blowing agent.

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.

This document describes systems and processes for forming synthetic molded slabs, which may be suitable for use in living or working spaces (e.g., along a countertop, table, floor, or the like).

The present invention relates to process for producing a hot blended material of amorphous silicon dioxidecrystalline silicon dioxide (Hot Blending silicaPheniSilic) from materials containing silicon dioxide such as sand, cristobalite, crushed glass, waste rock powder/burrs from process of producing artificial stone, waste products and by-products from the exploitation and processing of natural quartz stone. The present invention also relates to artificial stone product produced by using base resins such as unsaturated polyester, epoxy, acrylic or combination thereof and reinforcement is the hot blended material of amorphous silicon dioxidecrystalline silicon dioxide wherein the artificial stone has a flexural strength40N/mm.sup.2, a water absorption0.05%, an impact resistance3J, as well as process for producing this artificial stone.
