The minimum shelf life of Gypsum Plaster 3-4 months from the date of manufacture. 2.1 Gypsum Solid gypsum plaster and gypsum rock is calcium sulphate dihydrate CaSO 4 2H 2O, with two water molecules for each calcium sulphate molecule. The results showed that the ... plaster or gypsum binder to 7000 years B.C. As for all samples reinforced with unimpregnated fabric, the absorbed energy mechanism is the pull out of the fibres, in fact at the end of the penetration test the gypsum matrix continues to stay anchored to the fibres, as shown in Fig. The first layer applied should be cured for a day before applying the subsequent coats. Such strength relationships are affected by the configuration of the embedded insert, bearing ring dimensions, depth of embedment, and the type of aggregate (lightweight or … Usually, three types of plaster are used frequently with different purposes; namely the cement, gypsum plaster or Plaster of Paris and lime plaster. The test can be carried out in the field by simply heating small samples of the soil or sediment on a metal plate. Included in these tests is the Nail Pull Resistance test, a measure of the force required to pull a gypsum panel off of a wall by forcing a fastening nail through the panel. Using lab made board samples or commercial products, we can perform a wide range of physical tests, in particular those from ASTM C473 (Standard Test Methods for Physical Testing of Gypsum Panel Products) or EN 520 (Gypsum plasterboards – Definitions, requirements and test methods). It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. The humidified deflection of gypsum panel products is evaluated by supporting a specimen that has been cut with the long dimension perpendicular to the machine detection, supported horizontally, and subjected to high humidity. Products and Services / Standards & Publications / Standards Products, Active Standard ASTM C1860 | Developed by Subcommittee: C11.02, Permissions to reprint documents can be acquired throughCopyright Clearance Center   5.1 For a given concrete and a given test apparatus, pullout strengths can be related to compressive strength test results. The ability of gypsum panel products to resist nail pull-through is evaluated by determining the loaded required to push a standard nail head through the product. Gypsum plaster is also advisable where river sand/natural sand is not easily available for the construction. 4.1 The pull-off strength of a coating is a performance property that may be referenced in specifications. 1288:1982 Method of test for mineral gypsum and gypsum products.

Test results on a particular building may be variable depending on the specimen location, condition, and installation, and are subject to interpretation by the test specifier. USG is your source for quality drywall finishing plasters. In addition, 150 mm length fibers were used for pull-out test. No correlation shall be made between laboratory and field testing. 1.8 This standard may involve hazardous materials, operations, or equipment. Standard References. Lime. Gypsum plaster, white cementing material made by partial or complete dehydration of the mineral gypsum, commonly with special retarders or hardeners added. The test procedures are destructive in nature within the localized test areas and, after testing is concluded, require appropriate repair of the finish system as well as any underlying materials damaged during testing. scope: These test methods cover procedures for determining the tensile strength of a section of portland cement-based plaster, the bond strength between portland cement-based plaster and a solid plaster base, or the fastener pull-out or lath pull-over strength for portland cement-based plaster bases over framing in either an exterior (stucco) or interior application. Once a sample is received in the laboratory, an initial visual and low-power microscopical examination is conducted to determine the number of material types or layers, layer thickness, colour, and the relative … These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of these test methods.

[9] Link to Active (This link will always route to the current Active version of the standard. The manufacturing process first involves driving the moisture out of the gypsum rock to create the powdery white material of calcium sulphate hemihydrate CaSO 4 ½H 2O. ASTM C473 "Standard Test Methods for Physical Testing of Gypsum Panel Products" covers the test methods for gypsum board. Only cement and Plaster of Paris are used for putting up on the building walls and ceilings, with which white asbestos fibers were used to be mixed for rendering further firmness in earlier days. Gypsum. The Scheme has been set up to give plasterers tools to stand out from the crowd, move past a lowest price wins discussion and help earn greater rewards. The values obtained using the test methods are not purported to be representative of the actual wind load capacity or other structural properties of a specific portland cement-based plaster installation but may be helpful in assessing such load capacities. Applied in a plastic state (with water), it sets and hardens by chemical recombination of the gypsum with water. This standard does not purport to address all of the safety concerns, if any, associated with its use. From: Geomaterials Under the Microscope, 2013. Gypsum Plaster. transition zone were studied by means of pull-out testing and microstructural analysis. Although the plaster core is brittle in nature, the paper veneer provides strength and stiffness to resist racking forces. In case it is required, the plastering should be done in 2 coats. The test methods are intended to be used as a tool to quantitatively evaluate existing portland cement plaster cladding that is suspected of questionable bond or uncertain fastening to the substrate. The test methos appear in the following order: (1) flexural strength (Method A); (2) core, end, and edge hardness (Method A); (3) nail pull resistance (Method A); (4) humidified deflection; (5) end squareness; (6) nominal thickness; (7) recessed- or tapered-edge depth; (8) width; (9) length; (10) water resistance of core-treated water repellant gypsum panel products; and (11) surface water resistance of gypsum panel products with water-repellant surfaces. In fact a recent research on gypsum products reinforced with hemp and flax fibers showed that this addition could considerably delay the setting time of the pastes. Drill bit with centering point to obtain 20 mm dia. Abstract. Gypsum Board Testing. Gypsum plasters are perceived to have a number of advantages over lime, including easily controlled setting time according to function, less time delay between application of coats, they do not shrink on drying, and have excellent fire resistance. For especially hard finish In addition, 150 mm length fibers were used for pull-out test. SECTION 1.4 4.2 Because the test methods described in this standard are used for evaluation of portland cement-based plaster cured at least 28 days, load results obtained by either test method must be interpreted based on sound engineering practice, applicable building regulations, and codes having jurisdiction. Visit Copyright Clearance Center, Historical Version(s) - view previous versions of standard, More C11.01 Standards Wallboard panels consist of a gypsum plaster core covered on both surfaces with paper veneer. Test methods are detailed for the following: precautions for physical tests, reagents and materials, free water, fineness, normal consistency of gypsum plaster and gypsum concrete, setting time, setting time (temperature rise method), compressive strength, and density.
