1. The results of pozzolanic activity tests show that steel sludge has a higher reactivity due its higher loss of conductivity which is about 72.9% as against 43.3% for steel slag. This study was motivated by the need for the development of eco-friendly concrete, and the use of large quantities of steel slag as an industrial waste which is generated from the steel manufacturers. Usage in sinter mix-Steelmaking slag contains high percentage of CaO (mostly above 50 %). Steel slag is an industrial by-product of steel industry. The physical and chemical properties of slag aggregate evidenced the feasibility of using this material as a substitute for river sand. You do not need to reset your password if you login via Athens or an Institutional login. Specification for coarse and fine aggregates from natural sources for Concrete. This paper presents the results from experimental works completed at Qatar University to check the applicability of using steel slag aggregates in concrete … Steel slag can also be used to absorb contaminants like phosphate, magnesium, iron, calcium, silica and aluminium in the wastewater treatment process, but loses its effectiveness over time. Steel slag is produced as a by-product during the oxidation of steel pellets in an electric arc furnace. Murthi P.,Sivakumar V Indian concrete journal 2008 vol 82(7) pp 35. Deborah M.,Erinc Shay Kurt A.,Journal of Human Ecological and Risk Assessment 2002 Vol 8(4) pp The accumulated waste pipes of the various solid waste have become a problem of interest due to their non-biodegradable nature. If you have a user account, you will need to reset your password the next time you login. Mineral phases of SS are determined and … BibTeX Furthermore, the properties of concrete mix containing 100% RCA and 15% metakaolin are similar to that of normal concrete. This eco-friendly concrete was developed with steel slag as a substitute for natural sand. However, steel-reinforced concrete is often used in severe environments where sea water or deicing salts are present. Cement was partially replaced with glass powder at varying percentages such as 10%, 20% and 30% and several concrete cylinders were casted along with plain concrete specimen. IOP Conference Series Materials Science and Engineering. Experiments were conducted to determine the compressive strength; split tensile strength of concrete with various percentages of steel slag aggregate. The results of pozzolanic activity tests show that steel sludge has a higher reactivity due its higher loss of conductivity which is about 72.9% as against 43.3% for steel slag. Murthi P.,Sivakumar V Indian concrete journal 2008 vol 82(7) pp 35. The primary goal of this research is to experimentally study the effects on the various strength properties of concrete by using the M30 mix design, of a partial replacement of fine aggregates with steel slag and ground aggregate with rubber tyre. If the unit cost of steel slag modified mixes is the same as conventional dense graded mixes, overall project costs may increase because of the decrease in coverage by the heavier steel slag mix. Fly Ash (FA) and Rice Husk Ash (RHA) were used for preparing the binary blended concrete and Silica Fume (SF) was used for developing the ternary blended concrete. The concrete made with post-treatment steel slag was about 17% stronger than concrete made with conventional aggregates, and 8% stronger than raw steel slag. All the concrete mixes we, workability with a slump of 65 mm. Abstract. The 20% replacement of cement by glass powder met maximum compressive strength as compared to that of plain concrete. slag (GGBFS). L. Dongxue, et al. As a result of growing environmental awareness, iron and steel slag is highly regarded as a recycled material that can reduce impacts on the environment due to its resource-conservation and energy-saving effects. Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence. Mechanical properties are evaluated by conducting compressive, split tensile strength tests. The plant is featured by an innovative pneumatic transport system to convey the stabilizing agent to intercept the molten slag flux during the deslagging operation. It possesses the problem of disposal as waste and is of environmental concern. The test results confirm the possibility to use steel slag as the filler in the production of concrete. For this purpose, 12 different concrete mixtures with different water/cement ratios of 0.40, 0.55 and 0.70 which include steel slag aggregate as … Slag aggregates in asphalt. Afrani and Rogers (1994), on the other hand, recorded much greater scaling loss for concrete with high slag cement replacement compared to 100% OPC concrete. Environmentally friendly and reduced greenhouse gas emissions Steel slag is currently utilized both to treat wastewater, and as a concrete aggregate. All rights reserved. About 5% of worldwide man-made emission of CO 2 is generated. However, both materials show good reactivity in Ca(OH)2 solution. The concrete made with post-treatment steel slag was about 17% stronger than concrete made with conventional aggregates, and 8% stronger than raw steel slag. It is actually a byproduct of iron production. Isa Y.,Omer O.,Turhan B., Journal of material 2006.,vol 103(3).,pp203-208. Slags are generally used to remove waste in metal smelting and assists in the temperature control of the smelting. Steel slag is a by-product of the steel industry and can be used potentially as aggregate in asphalt mixture. For that we followed all the procedur, The aggregates of steel slag have high bulk density and specific gravity with moderate water absorption. The overall test results indicated that the waste glass powder could be utilized in concrete as a good substitute of cement up to particle size less than 75μm. This study evaluates the use of Steel Slag Aggregates (SSA) as substitute for natural aggregates in the production of hot mix asphalt (HMA) for road construction. 6.
