This paper presents research of the influence of concentration of nanomodifiers in the form of carbon nanotubes on the structure and physical and chemical properties of calcium sulfate hemihydrate. With the same nanomodifier content in the gypsum matrix, the maximum increase in strength is achieved by using CNTs functionalized with hydroxyl groups and makes 27–29 %. The increase in strength of the CNT-containing gypsum composite occurs due to the accelerated process of calcium sulfate dihydrate crystallization at the grapheme surfaceMetrics
