In the present disclosure, a cement board is disclosed. The cement board comprises a core having a first surface and a second surface opposite the first surface and a binder including a pozzolan material and a water-resistant additive, wherein the water-resistant additive is present in an amount of less than 5 wt. % based on the weight of the pozzolan material.

Synthetic pozzolans are produced using local materials to provide a cementitious material that is uniform in chemistry and properties independent of the location where the materials are obtained. Two methods of production are described. One is a high temperature process in which materials are processed in a semi-molten or molten state. The second process is a low temperature aqueous process.

Provided herein are processes for preparing a glass powder pozzolan product, the process including steps of: providing a crushed and clean waste glass; sorting the waste glass post pulverization through a process to take a coarse stream; adding a fine stream collected in the process and milling the coarse and fine streams to provide the glass powder pozzolan product. Glass powder pozzolan products, as well as systems for producing such glass powder pozzolan products, are also provided.

Methods for producing a blended pozzolan having one or more characteristics, such as one or more chemical and/or physical characteristic, in an established amount or range from two or more different pozzolans. Two or more pozzolans having different chemical and/or physical characteristics can be blended together and a chemical analyzer used to determine a chemical and/or physical characteristic of the blended pozzolan. Upon determining that the chemical and/or physical characteristic of the blended pozzolan is outside the established amount or range, modifying a blending ratio of the two or more pozzolans to restore the chemical and/or physical characteristic to the established amount or range.
