The application of gypsum is cement factories and gypsum powder factories. 0000004398 00000 n Standard Specification for Cement , lime gypsum 1. Available in MSR and HSR grades. Gypsum concrete is intended for use in the construction of poured-in-place roof decks or slabs. Two classes, based on the compressive strength and density, are covered. Gypsum plastering is an environmental friendly alternative to traditional sand-cement application for internal plastering surfaces. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard. Gypsum. trailer Typical physical requirements of the various API classes of cement are shown in Table 5. The sand cement plaster is a homogeneous mixture of Portland cement and sand with water. ASTM D3273 - Standard Test Method for Resistance to Growth of Mold on the Surface of Interior Coatings in an Environmental Chamber 9. Gypsum plastering is also a faster application method for internal surfaces, since it does not require time consuming water curing process. Purity : 90%; Size: As per customers requirements The Gypsum is sourced from reputable miners in the country and abroad.
