en.wikipedia.org/wiki/Gypsum_blockThe 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 ...
www.sciencedirect.com/science/article/pii/S095965…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.
pubs.acs.org/doi/10.1021/acs.jpcc.1c06213The results of the investigation of the influences of water-proofing additives on the crystal growth of gypsum products show that organic emulsion can be adsorbed selectively on the gypsum crystal surface, inhibiting the crystal growth along axis c [19].
