Properties Significant chemoresistance, and Suppression of alkali-aggregate reaction (type B and C). When the iron is processed using a blast furnace, slag and iron both collect at the bottom of the furnace.The molten slag must first be separated from the molten iron. At the present, most industrial slags are being used without taking full advantage of their properties or disposed rather than used. Ground granulated blast furnace slag is an eco-friendly material with regard to its production process and usage. Fig 2: Use of Slag cement in Sulphate and Chloride attack places. the hydration process if slag is an exothermic process, thus the generation of heat of hydration is slow. GGBS, Ground Granulated Blast Furnace Slag, is one of the most sought after sustainable building materials in India. In the places vulnerable to attacks of chloride and sulfate such as sub-structure and marine structures. Use of Blast Furnace Slag Aggregate in Concrete K.G. Tata Steel IBMD is one of the leading suppliers of GGBS and the product has been used in construction of many iconic structures in India. Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. IDENTIFICATION OF THE MATERIAL AND SUPPLIER Product Name GRANULATED BLAST FURNACE SLAG Supplier Contact Cockburn Cement A.B.N. Concrete properties can be improved using Fine Blast Furnace Slag (BFS). GBS and HSC Portland cement blends are made by blending Portland Cement and Ground Granulated Blast Furnace Slag (25% Slag blend -GBS and 60% Slag blend - HSC). In addition, recent research has examined its performance throughout the world [7 14]. Because of the deliberate hydration procedure, the slump retention and initial setting time are further. The Ground Granulated Blast Furnace Slag (GGBS) is obtained by grinding blast furnace slag in water or steam. Q.5. Table 3: Properties of Blast-Furnace Slag Cement. 7 Kg. Hiraskar and Chetan Patil Abstract-The Iron industries produce a huge quantity of blast furnace slag as by–product, which is a non–biodegradable waste material from that only a small percentage of it is used by cement industries to manufacture cement. Country Due to the white color of GGBFS, the cement color obtained is brighter colored when compared to conventional cement. Box 1886, PC 133, 2nd Floor,Tower 5, Panorama Mall. Blast furnace slag cement is used for (a)Dams (b)Bridge abutments (c)Retaining walls (d)All of these (Ans) ... MP GK 40 MCQs in Hindi and English; M.P GK QUIZ with 40 MCQs SET-3; To determine the liquid limit of soil as per IS: 2720 (Part 5) – 1985. Continue flushing until advised to stop by a Poisons Information Centre, a doctor, or for at least 15 minutes. Making cement is energy intensive, generating up to 176 kg CO 2 for each tonne of concrete manufactured. Used for structures meant for water retaining such as retaining wall, rivers, ports, tunnels for improvement in impermeability. Question No. This may affect construction schedules which needs … Ordinary Portland Cement (OPC): It is the most widely used type of cement and can meet the major requirement for construction. Test your knowledge about Civil Engineering – Concrete Technology by taking this Multi Choice Question (MCQ) quiz. The process involves cooling of the slag through high-pressure water jets, this leads to formation of granular particles. The initial strength achieved is less than the conventional concrete, but the superior ultimate strength attained is equivalent and sometimes higher than conventional concrete. Slag from blast furnace contains (a) alumina (b) lime (c) silica (d) all these. For road pavements, the cement generally used, is (A) Ordinary Portland cement (B) Rapid hardening cement (C) Low heat cement (D) Blast furnace slag cement. It employs 130 people across four sites in the UK: Scunthorpe, Wicken, Gurney Slade and Runcorn. Ground granulated blast furnace slag (GGBFS) is designated in ASTM C 989 and consists mainly of silicates and aluminosilicates of calcium. Q.5. Sign Up to The Constructor to ask questions, answer questions, write articles, and connect with other people. Ground granulated slag, combined with portland cement in the mixer, is the subject of discussion at this Forum. Blast Furnace Slag (BFS) cement is the combination of Ordinary Portland Cement (OPC) and fine Granulated Blast Furnace Slag (GBFS) gained as a byproduct in the steel making manufacturer with below 70% to that of cement. burning at high temperature. Blast Furnace Slag Cement; Air Entraining Cement; Hydrographic cement; 1. Materials 2019, 12, x FOR PEER REVIEW 2 of 12 against chloride ion diffusion is improved [6]. © 2009-2020 The Constructor. Blast Furnace Slag (BFS) cement is the combination of Ordinary Portland Cement (OPC) and fine Granulated Blast Furnace Slag (GBFS) gained as a byproduct in the steel making manufacturer with below 70% to that of cement. 8 Pick up the incorrect statement from the following: (A) Space between the exterior walls of a … , answer questions, write articles, and classified in the table below, 1! ; Air Entraining cement ; Hydrographic cement ; Air Entraining cement ; Air Entraining cement ; 1 cement...
