Gypsum plaster (calcium sulphate hemihydrate, CaSO ₄ ⋅ 0.5H ₂ O) is an air hardening binder with a low manufacturing carbon footprint, which is in principle recyclable, and is being increasingly promoted as a sustainable alternative to cement for indoor construction, prefabricated panels, drywall, decorative items and self levelling floor screeds. However, its rapid setting, fragility, low compressive strength, and high water absorption restrict its practical application. Chemical admixtures, including set retarders, accelerators, superplasticizers, cellulose ethers, starch ethers, hydrophobic agents, and foaming agents, are key technological tools to solve these problems and create application-specific gypsum binders. This review offers a critical, sustainability-oriented overview of the state of the art on chemical admixtures and additives for building gypsum. Main classes of admixtures are discussed in terms of chemical structure, physico-chemical mechanisms, and compatibility with industrial by-product gypsums, as well as their environmental sustainability compared to traditional alternatives. The review highlights the importance of bio and waste-derived admixtures that are essential for a circular economy in gypsum technology and underscores the need for further research on dosage standardization.
