Abstract:
Stone slabs, and systems and methods of forming slabs, are described. Some example slabs include a first pattern defined by a first particulate mineral mix and a second pattern defined by a second particulate mineral mix different from the first particulate mineral mix. Locations of the first pattern have a first average thickness perpendicular to the slab width and the slab length, and locations of the second pattern have a second average thickness perpendicular to the slab width and the slab length that is different from the first average thickness.
Abstract:
A strain tolerant recycled bitumen pavement composition comprising aggregate, recycled bitumen, and a specialized polymer modified bitumen. The specialized polymer modified bitumen may comprise bitumen and polymer, where the polymer comprises a preponderance of butadiene. The amount of recycled bitumen in the composition may be greater than 5% of the composition. Such high levels of recycled bitumen in a pavement composition, while desirable both economically and environmentally, typically produces layers with poor strain tolerance. The strain tolerance of the layer produced with the composition of the present invention, however, may be significantly higher due to the inclusion of the specialized polymer modified bitumen.
Abstract:
A space within a wellbore is sealed with a resin. Uncured resin is injected into a wellbore fluid within the space, and the resin is cured in the space by allowing a chemical reaction between the resin and a remaining fraction of the wellbore fluid in the space.
Abstract:
The present invention relates to a process for producing a pore-containing granulate, comprising the following steps: a) producing a foamed mass using sand, hydraulic binder, foaming agent and water, b) pouring the foamed mass into a filling mould, c) partially curing the mass over a first period of time at ambient pressure to form a green block having a first target strength, and d) demoulding the green block, the process comprising the further steps e) splitting the green block into at least two sub-blocks, 1) further curing the sub-blocks over a second period of time at ambient pressure until a second target strength is reached and g) breaking the sub-blocks to form pore-containing granulate with a desired particle size distribution. Furthermore, the present invention relates to a process for the production of a pore-containing artificial stone which contains the granulate as an additive.
Abstract:
The present invention relates to a method of manufacturing an artificial stone slab with veins comprises preparing a moldable hardenable fluid mixture of a first material (11); pouring said mixture into a mold (20) an upper face being exposed; engraving the exposed upper face with a predefined precise pattern of grooves (30) coinciding with a pattern of thin veins to be obtained; impregnating at least the inner faces (31) of said grooves (30) with a moldable hardenable fluid mixture of a second material (12), the color of both materials being different; causing the collapse and closure of the grooves, a visible pattern of thin veins of a second material with a natural look being left behind; curing the artificial stone slab by subjecting it to vibration, compression and vacuum until the fluid mixtures of the first material and of the second material are hardened.

Abstract:
The present invention relates to a process for reducing the content of free formaldehyde in a commercial phenol-formaldehyde resin, comprising the step of treating a phenol-formaldehyde resin with at least one phenol derivative or aniline derivative, wherein the pH of the resin is 7 or higher. The present invention further relates to a phenol-formaldehyde resin resulting from this process. The phenol-formaldehyde resin obtained by the process of the present invention may be used for the preparation of a binder composition for mineral wool products.
Abstract:
The present invention relates to an essentially isotropic slab of engineered stone, said slab having a thickness of about 2 mm to about 10 mm and preferably a width of about 0.2 m to about 3.0 m, wherein said slab is made from a composite material comprising about 50 to about 95 wt.% of solid filler and about 5 to about 50 wt.% of a thermoplastic binder, based on the total weight of the essentially isotropic slab, wherein the essentially isotropic slab has a warpage of less than about 1mm / m. The present invention also relates to a process for manufacturing an essentially isotropic slab of engineered stone.
