GYPSUMGypsum is the base mineral of high performing USG Industrial Plasters and GypsumCements. This highly versatile, basic mineral is finely ground and calcined toproduce a powder with uniform chemical and physical properties. In manufacturingindustrial plasters and gypsum cements, a portion of the chemically combinedwater is removed by calcination.The chemical equation that expresses the calcination of gypsum to form plaster is:CaSO4 2H2O heat CaSO4 1/2H2O 1-1/2H2OgypsumplasterwaterIn the presence of water, the plaster will revert to gypsum (this is the setting action).INDUSTRIAL PLASTERS& GYPSUM CEMENTSHOW DO INDUSTRIAL PLASTERS AND GYPSUM CEMENTS DIFFER?The difference is mainly in the size and shape of the crystals formed during themanufacturing process. This difference in crystalline structure has the followingeffects: Industrial plasters require 45 – 160 lbs. (20 – 73 kg) of water per 100 lbs. (45 kg)of plaster to achieve good workability Gypsum cements require 22 – 45 lbs. (10 – 20 kg) of water to achieve goodworkabilityCOMPATIBILITY WITH OTHER CHEMICALS, AGGREGATESIndustrial plasters and gypsum cements readily blend with chemicals and aggregatesto achieve special properties. Both wet and dry blending are done with variouschemicals, powders and granular materials. These include:talciron oxidekaolinresinsball ing agentswood fiberpolymersglass/polymer fiberspowdered glueset-time control additivesNote Except for special gypsum cement formulations, do not use coarse aggregates (gravel, stone, rip-rap, or any aggregatelarger than 10 mesh) as gypsum crystals do not readily bond to them.FIRE RESISTANCE AND NONCONDUCTIVITYIndustrial plasters and gypsum cements are noncombustible. With a coefficientof thermal conductivity (k) of 0.25 to 4.0 W/mK, depending on density andadditives, these materials assist in fire resistance. When exposed to heat, they donot exceed 212 F (100 C) until three quarters of the chemically combined wateris driven off. At about 1800 F (982 C), the CaSO4 portion dissociates intoquicklime (CaO) and sulfur trioxide (SO3). Dry gypsum is electrically nonconductiveand makes a good insulating medium.STORAGE AND USEWhen properly used, USG Industrial Plasters and Gypsum Cements are easy to workwith. All USG Casting Plasters and Gypsum Cements comply with the federal Labeling of Hazardous Art Materials Act, 12 U.S.C. Section 1277 and ASTM D4236. Keep indoors at temperatures between 65 F – 75 F (18 C – 24 C) and 45% – 55% RH. Donot stack more than two pallets high. Keep from drafts. Rotate stock. USG IndustrialPlasters and Gypsum Cements should be used within six months of the manufacturing date located on the package. Always follow handling and use directions andsafety warnings on the package.USG Industrial Plasters & Gypsum Cements 3
BENEFITSCONTROLLABLE SET TIMEIndustrial plasters and gypsum cements provide a controllable setting performancethat few other materials offer. By adding accelerators or retarders, you can shortenor lengthen its setting time as well as reproduce setting times from batch to batch.Industrial plasters and gypsum cements offer: A broad range of set times, from approximately 3 minutes to 20 hours Controllable demolding times, allowing for productivity optimizationNote Plaster sets with a sharp, definable, measurable action and sets faster than typical Portland cements and othercementitious materials.CONTROLLABLE EXPANSIONAmong cementitious materials, only industrial plasters and gypsum cements offercontrollable expansion—ranging from 0.05% to 1% linear expansion. Theseformulations can come closer to zero expansion than many other materials.Controllable expansion: Ensures high dimensional accuracy Ensures duplication of fine detail Provides a positive mechanical key when poured into a cavityEASE OF USEIndustrial plasters and gypsum cements can be fabricated or used in five main ways:1. Mixed as a fluid slurry, it can be cast or sprayed2. Worked in a plastic state by screeding or template forming3. Pressed between dies as a semi-wet powder4. Carved or machined as a solid5. In the plastic state can be vibrated into detailed molds for higher strength andaccurate reproductionIn fluid slurry form, plaster pours easily into flexible or rigid molds. The viscosityranges from nearly water to molasses. Plaster captures fine detail and can beparted from any nonporous surface. Properly formulated, it can be self-levelingand pump-able.In plastic mass form, plaster can be built up, troweled, added to, scraped away orsculpted as easily as clay. Viscosity ranges from that of butter to modeling clay.Plaster can be applied as a plastic mass to virtually any contour and will set inplace to produce a reverse contour.In solid form, casts from plaster formulation can be carved or machined usingconventional tools and equipment, including numerically controlled millingequipment.SOLUBILITYAmong casting materials, only industrial plasters and gypsum cements areself-cleaning in the mold—a basic requirement in the ceramics industry. This is dueto the slight solubility of gypsum (about two grams per liter of distilled water).Note If reduced solubility is not required, gypsum cements can be formulated to meet conditions—it’s that versatile.USG Industrial Plasters & Gypsum Cements 4
CONTROLLABLE STRENGTH, ABSORPTION, DENSITYAmong commercial materials, only industrial plasters and gypsum cementspossess extreme ranges in strength, absorption and density. Industrial plastersand gypsum cements offer: Compressive strengths (and hardness) that can range from that of the weakestchalk to four to five times greater than concrete Absorptions that can equal that of a rigid sponge to an impervious surfacethat sheds water A wide range of densitiesThis great range occurs by selecting the appropriate plaster formulation, thencontrolling the amount of mixing water.
