Titania nanofibers in gypsum composites: an antibacterial and cytotoxicology study [PDF]
Journal of Materials Chemistry B, 2014 Further developments of antibacterial coatings based on photocatalytic nanomaterials could be a promising route towards potential environmentally friendly applications in households, public buildings and health care facilities. Hereby we describe a simple chemical approach to synthesize photocatalytic nanomaterial-embedded coatings using gypsum as a ...

Gypsum Compositions Modified with Metallurgical Wastes
Solid State Phenomena, 2021The main results of the study of the influence of man-made products of the metallurgical industry on the properties and structure of gypsum binder are presented. It has been proved that the introduction of man-made modifiers, metallurgical dust, and slag leads to an increase in the strength properties and electric conductivity of the material, but ...

Thermal behaviour of gypsum based composites
Journal of Thermal Analysis and Calorimetry, 2007DTA/TG and X-ray investigations were carried out on different building composites in order to examine their relative hydration processes. The presence of lime, hemihydrate gypsum, ferosilicate, and some other wastes as leaner and hydrophobic additive in different proportions into composites provokes hydration reactions, leading to calcium silicate ...

The Preparation and Performance of Gypsum-Based Composites
Applied Mechanics and Materials, 2013Gypsum-based composites was produced using gypsum power(cement), PVA, white latex and sawdust via pouring process. The influences of water/ cement ratio, PVA/ cement ratio and glue/ cement ratio on release time, density and impact strength of the gypsum-based composites were investigated through orthogonal experiment.

Polymer composites based on gypsum matrix
AIP Conference Proceedings, 2016The role of polymers as retarder additives is to prolong the workability connected with setting time of gypsum. Various cellulose derivatives, soluble in water in concentration up to 1,5% by weight were applied taking different water/binder ratio. The hydration process of calcium sulfate hemihydrate (gypsum binder) into dihydrate (gypsum plaster) was ...

Characterization of the Gypsum Composite for Electrical Conductivity
American Journal of Chemistry, 2012In the nature, calciu m sulfate is found as gypsum (CaSO₄ , 2H₂O) in nonconductor compound which converting to plaster by the effect of heat and water loss. Into the autoclave, under pressure Alpha & Beta will be formed o f gypsum. In order to create conductivity properties in gypsum, a kind of poly mer called poly-aniline has been used which due to ...
