Blast Furnace Slag Powder By Different Grinding

Oct 14, 2014 The objective of this study was to assess the feasibility of utilization of grinding aids (GA) in the granulated blast furnace slag (GBFS) powder production. The GBFS powders were prepared with different GA, and their grindabilities, fluidities, reactivities and hydration characteristics were investigated. The experimental results indicate that although the improvement scales are various, all GA are very effective to explore the GBFS grindability.

Chloride ions penetrated reinforced concrete structures. Corrosion of reinforcing bars occurs because of cracks due to corrosion expansion, which is a problem of chloride damage deteriorating structures' performance. Blast furnace slag (from now on referred to as BFS ) is the inevitable by-product of steel product manufacturing as sustainable materials.

Jan 30, 2018 The applications of steel slag powder and steel slag aggregate in ultra-high performance concrete (UHPC) were investigated by determining the fluidity, nonevaporable water content, and pore structure of paste and the compressive strength of concrete and by observing the morphologies of hardened paste and the concrete fracture surface. The results show that the fluidity …

Jun 29, 2021 Steel slag powder and quartz powder with different particle sizes were prepared using a laboratory ball mill under different grinding times. Then, four types of steel slag powders with median diameter in the range of 10∼15 μm (denoted by R1), 15∼20 μm (denoted by R2), 20∼30 μm (denoted by R3), and 60∼70 μm (denoted by R4) were selected, respectively.

In this study, geopolymer is prepared from ‘ground granulated blast furnace slag’ (GGBS)–a powder from grinding the by-product of slag waste from blast furnace of steel plants. For comparison, conventional cement, Portland pozzolana cement (PPC) containing fly ash was considered.

Apr 23, 2017 All slags which disintegrate and fall into powder are wholly unfitted for cement-making. Those highly charged with mineral oxide compounds of sulphur, phosphorus, and large proportions of magnesia should also be at once rejected. Throughout the rest of the article iron blast-furnace slag will be simply referred to as slag. Granulating Slag
