A method of treating a subterranean formation comprising: forming a treatment fluid by adding a desired volume of a liquid concentrate suspension to at least a base fluid, wherein the treatment fluid comprises the liquid concentrate suspension and the base fluid, and wherein the liquid concentrate suspension comprises: (A) water; (B) an additive; and (C) a magnesium silicate clay, wherein the clay increases the viscosity of the water, wherein the liquid concentrate suspension is stable for a time period of at least 2 weeks; and introducing the treatment fluid into the subterranean formation.

A calcium-containing composition with fixed CO.sub.2 is produced by contacting a mixture of a calcium-containing composition before CO.sub.2 fixation and water with a CO.sub.2-containing gas. The calcium-containing composition, liquid water, and the CO.sub.2-containing gas having a temperature between 20 degree Celsius and 300 degree Celsius and a CO.sub.2 concentration between 1 volume % and 100 volume % are supplied to a reactor. By the supplied CO.sub.2-containing gas, the calcium-containing composition and water are made to flow in the reactor. Alternatively, the calcium-containing composition and water are in the reactor. Thus, CO.sub.2 is fixed in the calcium-containing composition and simultaneously the calcium-containing composition is dried to a water content of 5 mass % or less.

A process of preparing a concrete mixture includes the following steps: (a) providing a nano-sized non-sand silica and water; (b) mixing the non-sand silica with the water to form a silica-water mixture; (c) mixing an acid into the silica-water mixture to form a treated water; (d) mixing Portland cement and the treated water for a time sufficient to wet the Portland cement with the treated water to form a Portland/treated-water mixture; (e) mixing aggregate and the Portland-treated-water mixture to form an uncured concrete; and (f) allowing the uncured concrete to cure to form a cured concrete.
