Most of the steel mills in Bangladesh use induction furnace which produces large quantities of slags that have very little use except land filling. Therefore, feasibility of using this slag is examined in concrete with recycled aggregate, which is another waste product that is generated due to removal of old structures. Concrete with three target strengths, 17.23, 20.68, and 24.13 MPa ...
In order to get the best possible advantage when it comes to cost, it is vital that slag is recycled, and as such slag machinery is of the upmost importance without a shadow of a doubt. Before you think about using the machine, you should consider whether you have the knowledge that you need in order to be able to operate it safely.
Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes ...
How to deal with strange sounds from your washing machine. By Matt Stevens. If your washing machine has started making a worrying sound, this is the video for you.
I have a lot of stick welding experience but am new to the MIG. I tried the MIG this weekend with my first real project (wood racks out of old steel fence posts) using the .035 flux core wire that came with the welder (no gas). Although the welds looked and held good, it took a lot more effort to clean the slag off than I'm use to with the stick.
Electric arc furnace (EAF) slag is a by-product of steel production in electric arc furnaces. Several studies have tried to demonstrate its suitability in civil engineering application, such as in bituminous mixtures and cement-based materials, due to its good physical, chemical and mineralogical properties. Particularly the re-use as coarse aggregate for concrete production has been shown to ...
8/20/2014 · This work focuses on the use of copper slag, as a partial replacement of sand for use in cement concrete and building construction. Cement mortar mixtures prepared with fine aggregate made up of different proportions of copper slag and sand were tested for use as masonry mortars and plastering. Three masonry wall panels of dimensions 1 × 1 m were plastered.
Jun 01, 2010 · Use ER70S-6 wire when more deoxidizers are needed for welding on dirty or rusty steel. As for wire diameter, .030-inch diameter makes a good all-around choice for welding a wide range of metal thicknesses in home and motorsports applications. For welding thinner material, use a .023-inch wire to reduce heat input.
Considering, the acute shortage of river sand, huge short coming on quality of river sand, high cost, greater impact on road damages and environmental effects, The Construction Industry shall start using the manufactured sand to full extent as alternative, reduce the impacts on environment by not using the river sand.

Blast Furnace Slag - Material Description ORIGIN In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel. The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product.
By passing the molten slag through high volume high pressure water sprays, a glassy, sand-Type (granulated) material Is formed, known as Granulated Blast Furnace SIag.The color of this product is very similar to normal beach sand. The principal use is as Cement replacement (when ground), replacing 30-50% of Portland Cement in 'normal' concrete ...
