Methods of wellbore cementing are provided. A method of analyzing a solid particulate including: measuring a water requirement of the solid particulate; and determining an approximation of specific surface area of the solid particulate from the water requirement.

Methods of wellbore cementing are provided. A method of cementing may comprise calculating a lime to silica correlation for two or more cementitious components of a cement composition; and adjusting a concentration of at least one of the cementitious components such that the lime to silica correlation meets or exceeds a target.

A fuel made from co-products derived from a lignocellulosic biomass fermentation process is used to fuel a cement production process. Filter cake and syrup co-products are mixed and dried, then burned in a cement kiln to create the temperatures needed for cement production.

An embodiment comprises a method of treating a subterranean formation comprising: providing a treatment fluid comprising a kiln dust, biowaste ash, and water; and introducing the treatment fluid into a subterranean formation. Another embodiment comprises a method of cementing comprising: introducing a cement composition into a subterranean formation, wherein the cement composition comprises a kiln dust, biowaste ash, and water; and allowing the cement composition to set in the subterranean formation. Yet another embodiment comprises a method comprising: providing a spacer fluid comprising biowaste ash and water; introducing the spacer fluid into a well bore to displace at least a portion of a first fluid from the well bore; and introducing a cement composition into the well bore, wherein the spacer fluid separates the cement composition and the first fluid.

A method for forming a treated reclaimed bottom ash sand and a treated reclaimed bottom ash sand. The method includes providing reclaimed bottom ash sand. The reclaimed bottom ash sand is contacted with an aqueous composition having 0.5 to 3.0 M NaOH for a time greater than about 4 hours. The NaOH contacted reclaimed bottom ash sand is rinsed and decanted and iron is removed to form a treated reclaimed bottom ash sand having reduced hydrogen formation in concrete compared to the hydrogen formation of concrete utilizing reclaimed bottom ash sand. The treated reclaimed bottom ash sand includes reactive aluminum of less than 50% by weight of the reactive aluminum in the reclaimed bottom ash sand and the treated reclaimed bottom ash sand includes less than 2 wt % iron. A concrete formed from the treated reclaimed bottom ash sand is also disclosed.
