Portland Cement - ORDINARY GREY PORTLAND CEMENT 42.5 R - BS 12/1996 OR DIN EN 197-1:2000 OR ASTM C-15 Portland cement (often referred to as OPC, from Ordinary Portland Cement) is the most common type of cement in general use around the world because it is a basic ingredient of concrete, mortar, stucco and most non-specialty grout. It is a fine powder produced by grinding Portland cement clinker (more than 90%), a limited amount of calcium sulfate (which controls the set time) and up to 5% minor constituents as allowed by various standards There are two types of gray Portland cement: TS EN 197-1-CEM I with 42.5R and 52.5N standards. The strength of these types depends on the high amount of C3S in the cement. These are the most popular cement types, especially in the high strength concrete class and in the construction of tall buildings. It is popular in pre-stretched prefabricated applications in particular, tunnel mould systems and in the construction of mass housing.TYPICAL PROPERTIES PHYSICAL REQUIREMENTS Requirement as per IS:12269:1987 Unit Laboratory Test Result Fineness Specific Surface 225 ( Min ) m2/kg. 325 STANDARD CONSISTENCY % 31.50 Setting time (1) Initial (2) Final 30 ( Min ) 600 ( Max ) Minutes Minutes 125 175 Soundness Expansion measured by (1) Le - chatelier Method (2) Auto Clave 10.0 ( Max ) 0.80 ( Max ) m.m. % 1 0.12 Compressive Strength (1) 72 1h (3 Days) (2) 168 2h (7 Days) (3) 672 4h (28 Days) 27 ( Min ) 37 ( Min ) 53 ( Min ) Mpa Mpa Mpa 50 61 72 CHEMICAL REQUIREMENTS Lime Saturation Factor 0.80 to 1.02 Ratio 0.90 Alumina Iron Ratio 0.66 ( Min ) Ratio 1.36 Insoluble Residue(by mass) 3.0 ( Max ) % 0.89 Magnesia(by mass) 6.0 ( Max ) % 1.32 Sulphuric Anhydride(by mass) 3.0 ( Max ) % 1.76 Loss on ignition 4.0 ( Max ) % 1.02 Chloride Content(by mass) 0.10 ( Max ) % 0.035 The above cement complies with the requirement of IS : 12269 : 1987 For 53 Grade Ordinary Portland Cement MOQ- 16 MTNOTE: ONLY END USER CAN CONTACT
