Concrete is a mixture of cement, fine aggregate, coarse aggregate and water. Concrete plays a vital role in the development of infrastructure Viz., buildings, industrial structures, bridges and highways etc. leading to utilization of large quantity of concrete. On the other side, cost of concrete is attributed to the cost of its ingredients which is scarce and expensive, this leading to usage ...

replacement of cement. Fly ash, Ground Granulated Blast furnace Slag, Rice husk ash, High Reactive Meta kaolin, silica fume are some of the pozzolanic materials which can be used in concrete as partial replacement of cement 1 Micro Silica is extremely fine with particle size less than 1 micron and
The slag is dark grey in colour and is characteristically harder than blast furnace slag BFS. It has a density about 20 - 25 greater than basalt or BFS. It crushes to a cubical shape. EAFS in common with most steel slags, is subject to slight dimensional expansion until it fully hydrates.
JSW Composite Cement is the latest revolutionary offering specially designed for all your concrete-based construction requirements. A perfect blend of superior quality clinker and highly reactive slag and silica making it ideal for strength-bearing applications such as beams, columns, slabs, and foundations.
Aug 20, 2017 A composite mineral binder was prepared by mixing ground granulate blast furnace slag GGBS and steel slag GGBSsteel slag ratios are 1 1 or 3 2 by mass. The application of a composite binder in a massive concrete structure under severe sulphate attack is discussed by determining the hydration heat, adiabatic temperature increase, compressive strength, elastic

Figure. 1 Ground granulated blast furnace slag. Ground granulated blast-furnace slag GGBFS Hydraulic cement formed when granulated blast-furnace slag is ground to a suitable fineness commonly referred to as slag cement, or GGBFS.In India, annual productions of pig iron is 70-80 million tons and corresponding blast furnace slag are about 21 ...
Ground Granulated Blast Furnace Slag GGBFS Brief Description . GGBFS is formed when granulated blast furnace slag GBFS is further processed or ground using conventional cement clinker grinding technology.. Physical Description. On a casual examination, GGBFS can be off-white in appearance and could pass for a powder fineness typically between 380m 2 kg - 420m 2 kg.
Cement is an essential constituent for the production of concrete. Nowadays, the supplementary use of cement such as industrial by-product and agricultural waste material has become an integral part of concrete construction due to their cost effective and sustainable environmental benefits. The industrial metallurgical by product-Granulated Blast Furnace Slag GBFS contains a non ...
cement production or partial substitution of cement in concrete production reduces these CO2 emissions, especially if material is used which is seen as a waste of other processes, such as Fly Ash FA from coal power plants and Granulated Blast Furnace Slag GBFS from the iron and steel sector.
