Cement is a powdered mineral substance containing lime or gypsum which when mixed with water forms a paste that will set and harden into a hard and brittle material. For ready-mix producers and concrete product producers, CEMSlag TM is an eco-friendly, durable, cost-effective product that enhances the quality of your concrete. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. 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. The hydration rate of slag in blended cements then depends on the curing conditions. Blended cement can improve workability, strength, durability and chemical resistance of concrete. OPC is little bit costly compared to PPC. Clinker and gypsum ratio in cement. Compound Composition of Clinker / Cement Four major compounds formed from the oxides under high temperature in the kiln Name (Oxide Notation) - Shorthand Tricalcium silicate (3 CaO.SiO 2) – C3S Dicalcium silicate (2 CaO.SiO 2) – C2S Tricalcium aluminate (3 CaO.Al 2O 3) – C3A Tetracalcium aluminoferrite (4 CaO.Al 2O 3. Presented at University of Alabama Slag Cement Seminar April 30, 1981 he term "slag cement" is a very general one that can include many types of materials and combinations. It is known as slag cement in the local lingo. The PBSC has great chemical attack resistance power, Fineness, corrosion resistance power, lower permeability as compared to ordinary Portland cement OPC. As super-sulphated cement has more resistance than Portland blast furnace slag cement to attack by sea water, it also used in the marine works. It is less expensive and has less heat of hydration compared to OPC. Types of cement that are available and used in India. Cement is a binding material used to bind different type of construction materials together. The raw materials - iron ore, coke and fluxes - are fed into the top of the furnace. The slag constituent should remain in between 35% to 70%(IS:455-2000). 9. Four types of cement-1. studied the reactivity of slag-blended cement pastes, with 30% and 50% of slag hydrated at 10 °C, 30 °C and 50 °C for up to 6 months. The cement, gypsum adds so that the cement delay to solidify and there is sufficient time to work. As the name implies, it is produced from the mixture of three main elements, including ordinary cement [or Portland cement], ground granulated blast furnace slag, Portland clinker, and a little gypsum. The clinkers of cement are ground with about 60 to 65 percent of slag. 13. By twisting this internal mix ratio and by altering the chemical inputs, special types of cement can be produced according to the needs. White cement. Iron is extracted from iron ore in a blast furnace by a process known as reduction. 8. Because of this property this types of cement, therefore particularly recommended for use in foundation, where chemically aggressive conditions exist. High Alumina Cement Type IS-portland blast-furnace slag cement, Type IP and Type P-portland pozzolana cement, Type S-slag cement, Type I (PM)-pozzolana modified portland cement, and Type I (SM)-slag modified portland cement. This type of cement consists of mixture of Portland cement and ground blast-furnace slag. Escalante et al. Some of the more frequently seen types of blended cement are pozzolanic cement and Portland cement, blast furnace slag cement (BFSC) and Portland cement, BFSC and hydrated lime, and Portland cement, BFSC, and pozzolanic cement. The first entry on our list of different types of cement in Pakistan is blast furnace cement. Cement has been a very successful part of construction for a longer time than any of us can imagine. The slag is a waste product in the manufacturing process of pig-iron and it contains the basic elements of cement, namely alumina, lime and silica. Exposed to harsh environments, such as wastewater treatment and marine applications 2. Portland slag cement is used in all types of residential construction, commercial construction and industrial construction. What is Slag? This video explains what Portland Slag Cement is and important properties and uses. In Type IS the blast furnace slag content is between 25 % and 70 %.
