This research examined the properties of concrete containing grade 120 slag cement at replacement levels of 0, 30, and 50. The primary concrete properties studied were compressive strength, split-tensile strength, and deicer scaling resistance. Material variations included four sources of ordinary portland cement and two types of coarse aggregate.
Mar 01, 2013 The physical properties of steel slag aggregates are superior to those of crushed limestone aggregates. The major difference between the steel slag and crushed limestone aggregate is the bulk specific gravity. The bulk specific gravity of the steel slag aggregates is 3.34 while it is 2.4 for the crushed limestone aggregates.
benefits. The results indicate that the unit weight of Blast Furnace Slag aggregate concrete is lower than that of the conventional concrete with stone chips. The experimental result show that replacing some percentage of natural aggregates by slag aggregates causes negligible degradation in strength. The compressive
slag aggregate are their high angularity and porous surface tex ture. High sphericity less flat or less elongated result in better packing of the a ggregates while high angularity mor e cutting

Iron and steel slags are an industrial by-product that is manufactured under extensive quality control and can be used as aggregates in civil construction. These contain no organic impurities,...
Recent research found that some steel slag aggregates in RAP, with 92 steel slag aggregates, showed considerably high expansion potential, up to 6.2 swell. The overall RAP gave maximum expansion amounts of 1.69 and 1.46, respectively, which indicates lower tendencies to expand than virgin steel slag aggregates Deniz, Tutumluer, amp Popovics, 2010 .
Slag, generally classed as a synthetic aggregate also called artificial aggregate, is produced by altering both physical and chemical properties of a parent material, which may be produced and processed specifically for use as synthetic aggregate. A synthetic aggregate may also be the byproduct of manufacturing and a final burning processblast furnace slag is
This material is being used for road construction, as aggregates in concrete industry, brick manufacturing, and in pavement construction as engineering fill and has recently been tried in cement. ... T1 - Research on the use of Ferro-Chrome slag in civil engineering applications. AU - Al-Jabri, Khalifa S. PY - 2018214. Y1 - 2018214.
Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage. Doing so would both offset the cost of restoring abandoned mine areas, as well as decrease steel manufacturers current waste footprint.
This research studies the impact of different types of coarse aggregate on the behavior of geopolymer concrete based on both fly ash FA and ground granulated blast furnace slag GGBFS in different marine environments. Aiming to solve the problems caused by the construction and demolition waste and the depletion of natural aggregates, in the present study coarse recycled aggregates
To solve these problems, research has been carried out to use part of the slag as base course in road making and as aggregate in concrete mixes. The present work used composite beam with shear stud connector and replaced the conventional aggregate by slag at 100, 75, 50, 25, and 0 limestone proportions.
May 07, 2020 The Materials Processing Institute has secured a 118,363 research project to investigate methods of converting steelmaking slag into high-grade road surfacing material. For this research, the Materials Processing Institute has been awarded the grant in collaboration with industry and research partners, with which it will work on the project.

MRI Our company has extensive experience in the production and marketing of mineral and mineral slag products including air blasting abrasives SHARPSHOT iron silicate, slurry blasting abrasives, roofing granules , roofing backing sands, cement additives , road and roof asphalt fillers, and aggregates.
Steel industry results in accumulation of steel slag wastes causing severe environmental problems. These wastes can be recycled and replace natural aggregates resulting in sustainable green concrete. In this research, natural aggregates in self-compacting concrete SCC are replaced, wholly or partly, by steel slag coarse aggregates that were produced by crushing by

For the research gap that steel slag has not been used as aggregate in the chip seal for self-bonded and de-icing functions, the main objectives of this research were to recycle steel slag in chip seals as the aggregate, and to determine the functional and environmental performance of chip seal with recycled steel slag as aggregate.
Steel slag was then used as aggregate in HMA to verify the effects of its expansion characteristics on the volumetric and mechanical performance of the asphalt mixture. Four different asphalt mixtures were designed based on Marshall mix design, using asphalt cement pen. grade 5070, natural aggregate granite, and steel slag in three ...
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.
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 by-product more wisely as a replacement for both fine and coarse aggregates in
Depending on the used production technology, the steel slag can be divided into a basic oxygen steel slag, an electric arc furnace slag and a ladle furnace slag De Brito and Saika, 2013. The steel slag is used as a secondary cementitious binder, or aggregates for road construction Sheen et al., 2013 Manso et al., 2004 .
Most of the natural aggregates in the state of Ohio are shipped in from out of the state, whereas large steel slag deposits are locally available. The primary aim of this research was to evaluate the durability of concrete made with steel slag aggregates. This research
