strength by to EAF (Electric Arc Furnace) slag aggregate was used replacing 30% of crushed lime stone aggregate and it is found that the compressive strength increased in all ages [12]. According to [13], slag as coarse aggregate in normal strength concrete increases workability, compressive, flexure and split tensile
concrete and natural aggregate concrete, in high strength concrete series. Slag is a waste metallic material which might have long term delayed reactions, further experiments would be necessary to evaluate the durability of concrete made by steel slag aggregates. The following size of slag available from JSW Steel Ltd,04mm,4
In this study steel slag aggregate processed by several aging process was comparatively satisfied with fundamental properties as concrete aggregate, which are specific gravity, absorption, unit weight, percentage of solids and abrasion value etc. Chemical analysis is also observed to understand the effect of aging process in steel slag aggregate.
Apr 08, 2020· Concrete made with recycled steel slag is 17 percent stronger than traditional concrete. Disposing of slag is a millenniaold problem, .
In this study, the use of steel slag as fine and/or coarse aggregate in concrete is investigated. For this purpose, 12 different concrete mixtures with different water/cement ratios of, and which include steel slag aggregate as

suitability of the slag for use as fine concrete aggregate from the point of view of gradation. Concrete was made with a mix design of 1::3 (1 part cement; parts sand and 3 parts coarse aggregate). The cement used was CEM I Portland cement strength class 52,5N obtained
NATIOANL SLAG ASSOCIATION PELLETIZED LIGHTWEIGHT SLAG AGGREGATE Emery, Prepared For Concrete International, 1980 London, April 1318/80 SYNOPSIS The pelletizing process and the use of pelletized lightweight slag in structural and masonry concrete is described. Pelletlzed expanded slag has significant production and
Blast furnace slag, peletised slag and granulated slag can be used as an aggregate in concrete replacing primary aggregates in a number of applications. Mortar GGBS used as a cementitous component in mortars enhances workability and can allow further working time for the bricklayer.
Project Report on Copper Slag in Concrete Today I''m going to be shared about "Project Report on Copper Slag in Concrete" With advantages and disadvantages of copper slag in concrete so let''s get started. Introduction Traditionally soil, stone aggregates, sand,.
Aug 07, 2016· This study has been conducted to explore the possibility of utilization of steel slag in concrete as coarse aggregate. After collection of steel slag aggregate .
The two types of concrete aggregate that are manufactured using iron and steel slag as a raw material and which are covered by JIS standards are blast furnace slag aggregate and electric arc furnace oxidizing slag aggregate. Each of these types includes course aggregate and fine aggregate.
natural sand by copper slag, the flexural strength of concrete is increased by 14%.and all percentage replacement of fine aggregate by copper slag the flexural strength of concrete is more than normal mix. 4. Compressive strength and flexural Strength is increased due to high toughness of copper slag.
This report presents available information regarding the use of aircooled blast furnace slag (ACBFS) as coarse aggregate in concrete pavements. The report discusses ACBFS aggregate production and properties, and the properties of concrete produced with ACBFS coarse aggregate. Both the .

strength of Blast Furnace Slag aggregate concrete is found to be higher than that of conventional concrete at the age of 90 days. It has also reduced water absorption and porosity beyond 28 days in comparison to that of conventional concrete with stone chips used as coarse aggregate.
incorporated into concrete. The research was encouraging, since they show that using blast furnace slag as coarse aggregates in concrete has no negative effects on the short term properties of hardened concrete. Mohammed Nadeem1, Arun D. Pofale (2012), studied on replacement of coarse and fine aggregate in concrete by slag.
copper slag as fine aggregate on the properties of normal concrete. Akihiko and Takashi [3] investigated the use of slag from copper smelting as a fine aggregate in concrete. From mortar strength tests with a cement/slag/water ratio of 1/2/, the ball milled slag gave a higher strength. The effects of using several types of slag on mortar ...
grade 100 slag cement concrete. The objective of the current research project was to quantify the strength development and deicer scaling resistance of grade 120 slag cement concrete over a range of portland cement sources, aggregates and curing conditions used in Wisconsin.
Download PDF with chart HERE. Proportioning Concrete with Slag Cement. Concrete mixtures containing slag cement should be proportioned according to ACI The specific gravity of slag cement ranges from to, depending on the slag source, as compared to for portland cement.
Abstract. The successful incorporation of steel slag as aggregates in construction products requires the consideration of certain issues. Firstly, as steel slag is an industrial byproduct until recently disposed in landfills, the question is whether it is suitable for use in construction.
James G. Speight PhD, DSC, in Asphalt Materials Science and Technology, 2016. Slag. Slag aggregates are obtained by crushing of smelter slag or by special treatment of fireliquid slag melt (molten slag aggregates). Currently there are many types of concrete that are developed and used in construction that include metallurgical slags both as a binding component and as fillers.
