By twisting this internal mix ratio and by altering the chemical inputs, special types of cement can be produced according to the needs. Portland Slag Cement: PSC is created with a combination of slag … High Alumina Cement The properties of this cement are more or less the same as those of ordinary cement. Cement has been a very successful part of construction for a longer time than any of us can imagine. There are several different types of cements of which Portland cement, Siliceous (ASTM C618 Class F) Fly Ash, Calcareous (ASTM C618 Class C) Fly Ash, slag cement, and silica fume are the major types [9, 10].They differ from their chemical composition. Besides, it is comparatively economical than other types of cement. In this article we discuss about characteristics, types, advantages and uses […] It is less expensive and has less heat of hydration compared to OPC. As it has a low heat of hydration, PSC cement is used in the case of mass concreting such as dams, bridge piers, caissons, foundations, etc. It improves durability & resilience. Portland Slag Cement: 1. Ordinary Portland Cement 33 Grade Ordinary Portland Cement 43 Grade Ordinary Portland Cement 53 Grade Portland Slag Cement Portland Pozzolana Cement Coloured Cement/White Cement Sulphate Resisting Cement Low Heat Portland Cement Rapid […] It is formed from argillaceous, siliceous, calcareous etc. This cement was the mixture of clinker and granulated blast-furnace slag. If the clinker is high in alumina, the cement will solidify quickly. 13. OPC 33, 43 and 53 grade, Portland pozzolana cement, Portland Slag Cement (PSC) Rapid Hardening Cement Sulphate Resisting Portland Cement (SRC) Low Heat Portland Cement Hydrophobic Portland Cement, White Cement and coloured cement. Types of cement that are available and used in India. 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. Blast Furnace Slag Cement. Clinker and gypsum ratio in cement. i. 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. Types of cement - Designing Buildings Wiki - Share your construction industry knowledge. The first entry on our list of different types of cement in Pakistan is blast furnace cement. CEM II – Portland composite cement: This comprises of seven types which contain clinker and up to 35% of another single constituent. The activation by alkali and thermal activation may be synergistic. Related terms: Blast Furnace Slag Escalante et al. 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. PPC is widely used in mass concrete works such as dams, spillways, retaining walls, all types of reinforced cement concrete (“RCC”) work, underground structures, bridges, general building works and hydro-power stations. Super sulphate cement is made from well-granulated blast furnace slag about 80 to 85 %, calcium sulphate around 10 to 15 %, and portland cement about 1 to 2 %. Iron is extracted from iron ore in a blast furnace by a process known as reduction. 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. Blast Furnace Slag Cement. Because of this property this types of cement, therefore particularly recommended for use in foundation, where chemically aggressive conditions exist. Cement is a material with adhesive and cohesive forces that bind together other solid material matter into a compact durable form. Quick setting cement is used for constructions that need a quick setting, like underwater structures and in cold and rainy weather conditions. Portland Slag Cement is a hydraulic cement that is manufactured by grinding burnt furnace slag to suitable fineness and . Types of cement. Blast furnace slag cement is obtained by grinding the clinkers with about 60% slag and resembles more or less in properties of Portland cement. Which cement is costly OPC or PPC? 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. Slag cement can contribute to achieving LEED points to help your project attain this globally-recognized sustainability certification.
