  1. Gypsum block - Wikipedia

    • Because of the stored water, gypsum is a good fire protection building material. In the event of fire, the water crystals vaporize, actively slowing the spread of the fire. 展开

    Overview

    Gypsum block is a massive lightweight building material composed of solid gypsum, for building and e… 展开

    Manufacturing

    A gypsum block is made of gypsum plaster and water. The manufacturing process is automated at production plants where raw gypsum (CaSO4·2H2O) is ground and dried, then heated to remove three-quarters of the bound wat… 展开

    Specifications

    Gypsum blocks are manufactured in accordance with the European and British EN 12859 Standard. The dimensions of European standard gypsum blocks are: length: 666 mm, height: 500 mm. Three blocks thus mak… 展开

    Properties

    Gypsum blocks combine the advantages of classical masonry with modern drywall construction. Similar to masonry, walls built with gypsum blocks are massive, void-free and of high stability. Because no mortar, sand or plaster a… 展开

    Fire resistance rating

    Gypsum is a mineral and non-combustible building material (a class A1 building material in accordance with the German DIN 4102, the European EN 13501 or the British BS 476 or the American ASTM E119) consistin… 展开

    The PMHS significantly improved the waterproof performance of FGD gypsum blocks because its addition resulted in the formation of a hydrophobic film on CaSO 4 ·2H 2 O crystal surfaces, improving the morphology of gypsum crystals and enhancing block water resistance. In addition, blocks with PMHS discharged water and soluble salts during the ...

    Here, we present an atomic force microscopy (AFM) and molecular dynamics (MD) investigation to elucidate molecular-level details of the gypsum–water interface. Three-dimensional AFM data shed light into the hydration structure, revealing one water molecule per surface unit cell area in the lowest layer accessible to experiment.
