مصنع لتجهيز البوكسيت/concrete using wastes like slag from steel industries
Selfcompacted concrete (SCC) is cast in the formwork without compaction and it fulfills the formwork due to its own weight. SCC is considered to have many advantages in comparison with conventional concrete like improved construction quality, faster construction activity, reduced cost etc. SCC is produced with the same ingredients of normal concrete.
Sep 28, 2014· It represents the environment, which is our surrounding. Concrete which is made from concrete wastes that are ecofriendly are called as "Green concrete". Concrete wastes like slag, power plant wastes, recycled concrete, mining and quarrying wastes, waste glass, incinerator residue, red mud, burnt clay, sawdust, combustor ash and foundry sand.
concrete blocks production using secondary steelmaking slag. Introduction: Steel market plays a pivotal role in the diversification of the oilbased economies to grow its nonoil based commodities and create an industrial sector that competes internationally. One of the main commercial processes for steelmaking is the Electric Arc Furnace
The iron content is the major basic difference between BF slag and steel slag. In BF slag, FeO is around %, whereas, in case of steel slag, total iron content varies from 16 to 23%. The chemical analysis of granulated BF slag and steel slag generated in steel plants are given in Table 2. 163 SLAG IRON AND STEEL USES
The increasing demand and consumption of cement have necessitated the use of slag, fly ash, rice husk ash (RHA), and so forth as a supplement of cement in concrete construction. The aim of the study is to develop a zerocement binder (ZCem) using slag, fly ash, and RHA combined with chemical activator. NaOH, Ca(OH)2, and KOH were used in varying weights and molar concentrations.
Although blast furnace slag contains a small component of elemental sulfur (1 to 2 percent), the leachate tends to be slightly alkaline and does not present a corrosion risk to steel in pilings (10) or to steel embedded in concrete made with blast furnace slag cement or aggregates. (11)
This paper presents the results of an experimental investigation on the effect of using Steel, Aluminum and Copper waste as cement replacement on mortar and concrete cubes and cylindrical samples. In this study we tested the possibility of using wastes of mineral substances such as Iron, Copper and Aluminum in process of the production
Environmental and economic factors increasingly encourage higher utility of industrial byproducts. The basic objective of this study was to identify alternative source for good quality aggregates which is depleting very fast due to fast pace of construction activities in India. EAF oxidizing slag as a byproduct obtained during the process in steel making industry provides great opportunity ...
Concrete mix design is the science of deciding relative proportions of ingredients of concrete, to achieve the desired properties of concrete. Use of mineral admixtures like fly ash, slag, metakaolin and steel fibre have revolutionized the concrete technology by increasing its strength and durability of .
