A construction material, a hydrophobic, optionally multi-cellular, inorganic particulate material for use in the construction material, for example, to improve the crush strength and/or stability of the construction material, a method of making the construction material, constructions comprising the construction material, and a method of improving the stability of a construction material.

Hydrophobic construction material

Spherical and rod-shaped proppants and anti-flowback agents made from flash calcined clays, such as flash calcined kaolin, possess high strength and high conductivity. The starting material may optionally be milled to achieve better compacity and crush resistance in the final proppant or anti-flowback agent. A fracturing fluid may include the rods or spheres alone, or in combination with each other or other proppants or anti-flowback agents of different shapes.

Proppants and anti-flowback additives comprising flash calcined clay, methods of manufacture, and methods of use

A method of grinding a particulate material, comprising grinding said material in a stirred mill in the presence of a grinding media comprising rod-shaped particles, wherein said rod-shaped particles have an aspect ratio of equal to or greater than about 2:1.

Grinding method

Filter-aid materials are disclosed herein, as well as processes, systems, and methods using such filter-aid materials for filtering and removing particles and/or constituents from a fluid. Further disclosed herein are filter-aid materials and processes, systems, and methods using such filter-aid materials for filtering and removing particles and/or constituents from a fluid, wherein the filter-aid material comprises at least one composite filter-aid having novel pore size distribution and comprising at least one adsorbent component formed in-situ on at least one filtration component.

Composite filter aids having novel pore size characteristics

Spherical and rod-shaped proppants and anti-flowback agents made from sillimanite minerals possess high strength and high conductivity. The sillimanite minerals may be selected from the group consisting of kyanite, sillimanite, and andalusite and may be used alone or in combination with other materials, such as bauxite, kaolin, meta-kaolin, pure or technical grade alumina (about 98%-99.9% alumina by weight), alumina-containing slag, zirconia, silica, iron, alkali elements (such as calcium, magnesium, and sodium), and virtually any other mineral containing alumina. The starting material may optionally be milled to achieve better compacity and crush resistance in the final proppant or anti-flowback agent. A fracturing fluid may comprise the rods or spheres alone, or in combination with each other or other proppants or anti-flowback agents of different shapes.
