摘要： A concrete with natural volcanic pumice and a method of manufacturing a concrete with natural volcanic pumice are presented. The concrete with volcanic pumice replaces between 10%-20% of ordinary Portland cement present in conventional cement with ground natural volcanic pumice. The ground natural volcanic pumice is sourced from the Chagai magmatic arc and has a particularly large percentage of aluminosiliceous content. The concrete with natural volcanic pumice has improved compressive strength and water resistance.

摘要： Disclosed herein is a composition comprising a cementitious material, a pozzolanic material, aplite, and an aqueous fluid. Also disclosed herein is a method of servicing a wellbore penetrating a subterranean formation, comprising: placing the composition into the wellbore; and allowing the composition to form a set cement. The composition can develop suitable mechanical properties and permeability after setting in a wellbore and be expansive.

摘要： A system and method for applying a construction material is provided. The method may include mixing blast furnace slag material, geopolymer material, alkali-based powder, and sand at a mixing device to generate a non-Portland cement-based material. The method may also include transporting the non-Portland cement-based material from the mixing device, through a conduit to a nozzle and combining the transported non-Portland cement-based material with water at the nozzle to generate a partially liquefied non-Portland cement-based material. The method may further include pneumatically applying the partially liquefied non-Portland cement-based material to a surface.

摘要： It has been unexpectedly discovered that the addition of a natural or other pozzolan to non-spec fly ash significantly improves the properties of the non-spec fly ash to the extent it can be certified under ASTM C618 and AASHTO 295, as either a Class F or Class C fly ash. The natural pozzolan may be a volcanic ejecta, such as pumice or perlite. Other pozzolans may also be used for this beneficiation process. Many pozzolans are experimentally tested and may be used to beneficiate non-spec fly ash into certifiable Class F fly ash. Additionally, this disclosure provides a method of converting a Class C fly ash to a more valuable Class F fly ash. This discovery will extend diminishing Class F fly ash supplies and turn non-spec fly ash waste streams into valuable, certified fly ash pozzolan which will protect and enhance concrete, mortars and grouts.

摘要： A composite filter aid may include acid-washed diatomaceous earth and a low extractable metal mineral. A method for making a composite material may include blending an acid-washed diatomaceous earth and a low extractable metal mineral, adding a binder to the blended diatomaceous earth and low extractable metal mineral, and forming the composite material from the acid-washed diatomaceous earth, the low extractable metal mineral, and the binder. A method for filtering a liquid may include providing a liquid for filtering and filtering the liquid through a composite filter aid that includes an acid-washed diatomaceous earth and a low extractable metal mineral.
