A cement composition for use in a well that penetrates a subterranean formation comprising: cement; water; an environmentally-friendly curable resin having two or more epoxy functional groups; and a curing agent that causes the curable resin to cure when in contact with the curing agent. A method of cementing in a subterranean formation comprising: introducing the cement composition into the subterranean formation; and allowing the cement composition to set after introduction.

A plaster-based material, in particular a plasterboard intended for the interior fitting of dwellings, contains a metal complex of EDTA. The plaster-based material is used for reducing the amount of volatile organic compounds present in the atmosphere inside dwellings, offices or public buildings.

The composition for preparation of a fire resistant interlayer includes an aqueous alkali silicate solution and a silicon dioxide compound. The composition has a molar ratio of silicon dioxide (SiO2) to alkali metal oxide (M2O) of larger than 2. The composition further includes a stabilisation agent and the stabilisation agent includes zinc (Zn).

Lithium-containing cement admixtures including a calcium aluminate phosphate cement; a lithium-ion-containing compound; and an aqueous base fluid and methods of introducing the lithium-containing cement admixtures into a subterranean formation. The lithium-containing cement admixtures may further comprise an aluminosilicate or an additive including a set retarder, a set accelerator, a suspension aid, a density reducing agent, a fluid loss control agent, a defoamer, and any combination thereof.

A method of treating a subterranean formation penetrated by a wellbore comprises: introducing into the subterranean formation a treatment fluid comprising a carbonate producing agent, urea, and a cation source; allowing a carbonate precipitate to form, the carbonate precipitate comprising a cation from the cation source and having a water solubility of less than about 0.1 g/100 mL at 25 C. and atmospheric pressure; and reducing or substantially preventing the passage of formation particles from the subterranean formation into the wellbore while allowing passage of formation fluids from the subterranean formation into the wellbore.
