Portland Slag Cement-Definition, Advantages and Uses

Although blast furnace slag cement has many advantages over ordinary portland cement. The physical properties are similar to OPC. But it has a low heat of hydration and it gives better resistance to chlorides, soils, sulfates and alkalies. You know that slag is byproduct formed in blast furnace slag during smelting or refining of ore.

What is Portland Slag Cement? Construction Materials In

Feb 29, 2016 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. All compositions produce high ultimate strength, but as slag content is increased, initial strength is reduced, while sulfate resistance upsurges and heat evolution moderates.

Engineering Seminars: SLAG CEMENT

Dec 18, 2010 Slag cement should be substituted for Portland cement on a one-to-one basis by mass. Specific gravity of slag cement ranges from 2.85 to2.94, depending upon the slag cement source-as compared to 3.15for Portland cement. The difference in specific gravity means a greater volume of slag cement will be used to replace the same mass of Portland cement.

What are high-density aggregates?

A. High-density aggregates generally consist of high-density minerals or rocks, or they consist of man-made materials, such as steel or iron. High-density aggregates are used to produce concrete that has higher than normal density, usually for radiation shielding or an application where high-density concrete is needed for counter balancing

Aug 11, 2018 Coarse aggregates are particulates that are greater than 9.5mm. The usual range employed is between 9.5mm and 37.5mm in diameter. Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed because of its
