Portland cement is an excellent building material generally used for its excellent binding properties giving strength to structural elements. Portland Slag Cement (PSC) Slag cement reduces the threat of sulfate attack, and alkali-silica reaction (ASR), improves resistance to deicing salts and chlorides and provides better protection for steel reinforcement. Blast furnace slag cement 4. Use concrete composed of a mixture of portland cement, aggregate, water, and, where specified, admixtures, pozzolan and ground granulated blast furnace slag. The Portland slag cement is one such cement, which uses blast furnace slag in the production of cement. But the rate of hardening comparatively low. 2. As the name indicates, it is white in color. Slag cement, previously known as ground-granulated blast-furnace slag \⠀䜀䜀䈀䘀匀尩, has been used in concrete for well over 100 ye\ൡrs \⠀䄀䌀䤀 ㈀ ㄀㄀尩. At JSW Cement, we use superior quality slag produced at our steel manufacturing plant, conforming to IS: 12089 standards for producing PSC. Slag is, essentially, a non-metallic product comprising of more than 90% glass with silicates and alumino-silicates of lime. Applications of Type V Cement. As per ASTM 150 (American […] Portland blast furnace cement is similar to OPC in terms of soundness, fineness and strength. Using slag cement to replace a portion of Portland cement in a concrete mixture is an efficient way to make concrete more consistent. All compositions produce high ultimate strength, but as slag content is increased, initial strength is reduced, while sulfate resistance upsurges and heat evolution moderates. Type IS Portland-Slag Cement Type IP Portland-Pozzonlan Cement Type IT Ternary Blended Cement. Slag percentage should be 25 to 70% of the weight of Portland blast furnace slag cement. It is known as slag cement in the local lingo. For example Type IP(MS) is a portland-pozzolan cement with moderate sulfate resistance properties. Portland Slag Cement . Application/Use: It is used for architectural beauty, interior and exterior decorations such as terrazzo tiles and floorings, ornamental concrete products such as idols Features: 1. Slag is by product of steel production, essentially, a non-metallic product comprising of more than 90% glass with silicates and alumino-silicates of lime. The portland slag cement has many advantages over ordinary portland cement (OPC). Different types of Portland cement. chemical use in manufacturing portland slag cement in grinding unit mining. Portland Slag Cement (PSC) This cement was used … For more information visit our site - doublebullcement.com 9. Blast furnace cement is also known as slag cement. Slag is, essentially, a non-metallic product comprising of more than 90% glass with silicates and alumino-silicates of lime. Contents:Uses of Different Types of Portland Cement1. The use of slags in raw mixes increased the mechanical strength of … Due to its much lower lime content and lower permeability, slag is effective in preventing efflorescence when used at appropriate levels. Portland blaze or fly ash cement 3. Read More. Maximum Guarantee in Every Foundation. ii. Blast Furnace Slag Cement. High alumina cement is obtained by mixing calcining bauxite and lime with clinker during the manufacturing process of OPC. The first entry on our list of different types of cement in Pakistan is blast furnace cement. For the bulk and continuous manufacturing and production of Portland Cement following mineral materials are used: calcareous materials (limestone or chalk), argillaceous material (shale or clay), blast furnace slag, silica sand, iron ore, and gypsum as raw material. The Slag cement is more resistant to the attack of weathering agencies. At JSW Cement, we use superior quality slag produced at our steel manufacturing plant, conforming to IS: 12089 standards for producing PSC. Hence, during production, the amount of carbon dioxide released in the atmosphere will be reduced. It is manufactured by either inter-grinding or blending, OPC Clinker (35% – 50%),slag (45- 65% ) and gypsum (3-5%). The GGBS is a waste product from the steel manufacturing industry. Portland slag cement (CEM II/A-S and CEM II/B-S): This comprises of clinker and blast furnace slag which originates from the rapid cooling of slag obtained by smelting iron ore in a blast furnace. PORTLAND CEMENT CONCRETE 346-1 Description. The use of technogenic raw materials as input products in the production of portland cement provides for considerable reduction of energy consumption during clinker burning. We Prepare Our Products Using State Of The Art Technology Under Strict Quality Assurance. Properties of Portland Slag Cement. Generally, the use of high-grade cement offers many advantages for making stronger concrete. At JSW Cement, superior quality slag produced at the steel-manufacturing plants is used, along with clinker and gypsum to create PSC, using state-of-the-art technology, through roller press and vertical roller mill. Advantages and Use of Ordinary portland cement. I didn't find any problem. Leached concentrations of 0.13 and 0.02 mg/L have been recorded for CLSMs with Portland cement and blast furnace slag cement, respectively, used as a binder alongside SSA. Portland slag cement is obtained by mixing Portland cement clinker, gyplum and Ifanulated sla,in suitable proportions and grinding the mixture to get I thorough and intimate mix between the consti ­ tuents. I had practically used PPC cement in almost all projects. Portland Slag Cement, commonly known as PSC, is blended cement. Typical chemical composition contains calcium oxide 40%, silica 35%, alumina 13% and magnesia 8%. What is cement made of? It is also used as a basic ingredient in the mortar, stucco, and non-specialty grout. The PSC is also called Blast Furnace Slag Cement because of its make. When a mix includes 20% fly ash, this will provide savings of 3.5% in cost. About 25 to 70 percent of waste slag can be added for production which makes the manufacturing of cement more economical. Portland slag cement is the most suitable cement for concrete paths, mass concrete uses, structures and bases, Pre-cast concrete, concrete open to seawater and oceanic use. \ Portland blast-furnace slag cement, or Blast furnace cement (ASTM C595 and EN 197-1 nomenclature respectively), contains up to 95% ground granulated blast furnace slag, with the rest Portland clinker and a little gypsum. Among the measurable improvements are higher workability, higher finishability, lower permeability, improved resistance to aggressive chemicals, more consistent plastic and hardened properties, flexural strengths, and highest compressive strength. About 98% of the cement is made from intermediate products, ie kinkar. Type V cement is used only in construction where concrete is going to be exposed to very extreme suphate action. Portland Slag Cement, commonly known as PSC, is also a kind of blended cement. The study reveals the mineral formation features caused by the change of the liquid phase composition and crystallization of silicate phases. When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the hydrated cement paste (pozzolanic reaction), resulting in a more refined microstructure than that of a plain portland cement. These are designated by letters in parentheses following the cement type. It may also be manufactured by separately grinding Portland cement clinker, gypsum and granulated slag and then mixing them intimately. Chemical composition and physical properties meet the specification of ordinary portland cement. It is created with a combination of upto 45- 50% Ground Granulated Blast Furnace Slag (GGBS) and Ordinary Portland Cement (OPC) [Quora] Chemical Composition of Ground Granulated Blast Furnace Slag. Blast Furnace slag cement is made up of the Ordinary Portland Cement clinkers, gypsum and Ground Granulated Blast Furnace Slag (GGBS) added in certain proportions.
