In this project 5%10% of steel slag are replaced as cement. The chemical composition is mentioned below in table A. Table A.
concrete; from the results obtained, it is found that glass powder can be used as cement replacement material up to particle size less than 75μm to prevent alkali silica reaction. Keywords: Experimental, Investigation, Coarse Aggregate, Steel Slag, Concrete I. INTRODUCTION Slag is a partially vitreous by product of the process of smelting ore.
Aug 28, 2018· How GGBS is Made inside Steel manufacturing Factory On our planet, Iron is not found in pure state, we call it as ore. Iron Ores are often oxidized and mixed with Silicates (sand). During manufacturing of steel these ores are heated above 1600 degree centigrade in .
The optimum dosage of Ground granulated blastfurnace slag (GGBS) for replacement in concrete was reported to be 2030% by mass to provide higher compressive strength compared to the concrete made with only cement. Sustainability. Since GGBS is a byproduct of steel manufacturing process, its ...
difference in the level of deicer scaling that occurred in slag cement concrete versus OPC concrete (Dubovoy, et al, 1986). Afrani and Rogers (1994), on the other hand, recorded much greater scaling loss for concrete with high slag cement replacement compared to OPC concrete. Also noted was a difference in deicer scaling resistance apparently
Dec 31, 2018· The replacement of river sand by slag aggregate provides dual advantage of reducing disposal problems in steel industries and conserving the natural resources. In this study, slag aggregate originated from induction blast furnace has been used.
Steel slag is an industrial by product obtained from the steel manufacturing industry. It is a nonmetallic ceramic material formed from the reaction of flux such as calcium oxide with the inorganic nonmetallic components present in the steel scrap. Most of the volume of concrete comprises of aggregates. CONTINUE READING
Experimental Study On Partial Replacement Of Fine Aggregate By Steel Slag And Coarse Aggregate By Pebble Stone In Concrete, Engineering Student, Sree Sastha Institute of Engineering and Technology, Chennai. 2Professor, Dept. of Civil Engineering, Sree Sastha Institute of Engineering and Technology, Chennai..
Dec 01, 2016· So from the above discussion and Fig. 6, it can be concluded that steel slag concrete, WFS slag concrete, class F fly ash concrete, and palm oil clinker concrete show low workability whereas a slump value increases with replacement ratio increases in copper slag and GBF slag concrete, but in case of bottom ash concrete the slump value increases ...
Slag cement is commonly found in readymixed concrete, precast concrete, masonry, soil cement and high temperature resistant building products. While there are many applications and benefits of slag cement, a few are highlighted below and detailed information sheets are located here.
Replacement Of Sand With Steel Slag In Concrete. Of using iron slag as partial replacement of sand in and steel making slag are by products of the iron making and steelmaking date, these types of slag have been widely used in cement and as aggregate for civil report presents an investigation of.
Nov 02, 2017· This paper presents the results of a research dealing with the use of unstable steel slag as a substitute for natural aggregate in the production of concrete. Portland cement CEM I and alkali activated hybrid cement HCEMENT were used as the binder.
The results were compared with conventional concrete property can be maintained with advanced mineral admixtures such as steel slag powder as partial replacement of cement 0 to 40%.
Steel slag is currently used as aggregate in hot mix asphalt surface applications, but there is a need for some additional work to determine the feasibility of utilizing this industrial byproduct more wisely as a replacement for both fine and coarse aggregates in a conventional concrete mixture.
Several studies proved that the use of steel slag in concrete as aggregate improves the mechanical and durability properties [6–29]. A very few researches have been performed regarding the utilization of EAF oxidizing slag in concrete. EAF oxidizing slag is an industrial byproduct obtained from the steel manufacturing industry.
Aug 08, 2020· The increased proportion of traffic volumes on roads is often the cause of distress to the pavement structure. The use of strong and durable steel slag (S) as an aggregate material in asphalt concrete can enhance the loadbearing capacity while at the same time conserving natural resources, resulting in a sustainable asphalt pavement system.
Apr 09, 2020· MELBOURNE, AUSTRALIA, APRIL 9, 2020 Researchers have shown how a byproduct of steel making can be used to both treat wastewater and make stronger concrete, in a zerowaste approach to help advance the circular during the separation of molten steel from impurities, steel slag is often used as a substitute aggregate material for making concrete.
STEEL SLAG Steel slag are the industrial byproducts from a greatest interest to the pavement construction industry but minimum of slag will be introduced in concrete replacement as cement. In this project 510 of steel slag are replaced as cement. The chemical composition is mentioned below in table A.
Strength Behaviour of Geopolymer Concrete by Partial Replacement of Coarse Aggregate with Steel Slag Deepth C1, B Rajeevan2 1,2Government College of Engineering Kannur, Kerela, India Abstract—The development of sustainable and environment friendly construction materials has gained major attention recently because of depletion of natural resources.
S. T. Borole (2016) concluded in their experimental work on concrete grade M30 that the compressive strength, the Split tensile strength, the flexural strength increased by 25% by fine aggregate weight in the percentage of steel slag and then decreased considerably in the further replacement of steel slag in concrete.
concrete development. The present research work deals with a view to develop efficient concrete by addition of steel slag to evaluate the effectiveness of the use of steel slag as a partial replacement in sand To replace Sand with various percentages 10, 20, 30, 40% of steel slag waste in M25, M30 M35 concrete. Investigation have
The applications of steel slag powder and steel slag aggregate in ultrahigh 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 of the paste containing ...
Keywords: Compressive strength, Flexural strength, Tensile strength, Steel slag, Replacement GENERAL Concrete is the most widely used material on earth after water. Many aspects of our daily life depend directly or indirectly on concrete. Concrete is prepared by mixing various constituents like cement, aggregates, water, etc.
