A method of using a gas control additive to provide gas migration control in a wellbore includes the steps of mixing the gas control additive with a cement to form a cement slurry, where the gas control additive includes a semi-permeable membrane and a scrubbing agent, such that the semi-permeable membrane forms a shell around a core such that the scrubbing agent is in the core, introducing the cement slurry to the wellbore, and reacting the scrubbing agent with an antagonistic gas to produce a helper byproduct, where the antagonistic gas migrates from a hydrocarbon-bearing formation into the wellbore and permeates through the semi-permeable membrane to the core of the gas control additive.

A composition comprising: (a) fly ash cementitious binder; and (b) a chemical activator selected from sodium silicate, potassium silicate, sodium sulfate, sodium phosphate, calcium sulfate, potassium sulfate, potassium phosphate, CaO, Fe.sub.2O.sub.3, sodium chloride, calcium chloride, fine fraction of concrete waste from construction or demolition, cement kiln dust, or a combination thereof, wherein the fly ash is the only cementitious binder present in the composition and the CaO activator, if present, is present in an amount 10 weight percent, based on the total dry weight of the composition.

Disclosed are a semi-transparent ceramic sheet decorated through ink light-absorbance and a preparation method thereof. The semi-transparent ceramic sheet comprises a semi-transparent green body, an inner inkjet pattern layer infiltrating into the semi-transparent green body from an upper surface of the semi-transparent green body, a decoloration glaze layer located on the upper surface, and a surface pattern layer located on the decoloration glaze layer. The decoloration glaze layer is capable of decoloring the ink of the inner inkjet pattern layer. The semi-transparent ceramic sheet is provided with the decoloration glaze layer so that the inkjet decoration of the inner inkjet pattern layer cannot be displayed on the surface, and the decorative pattern on the surface of the green body is the surface pattern layer and the inner inkjet pattern layer is completely in the inner layer of the green body.
