Performance of steel slag and steel sludge in concrete

Construction and Building Materials, 2016
The impact of environmental cleansing through inclusion of hazardous wastes in cement related products cannot be overemphasized. This paper presents outcomes of laboratory experiments on the utilizations of electric arc furnace steel slag and steel sludge (by-products from steel making industries) as cement replacements in concrete.

Material Properties of Steel Slag-Cement Binding Materials Prepared by Precarbonated Steel Slag

Journal of Materials in Civil Engineering, 2018
AbstractNowadays, a large amount of steel slag (SS) not only occupies land resources but also pollutes the environment, and the low early strength and poor stability limit the application of SS in ...

An Overview of Utilization of Steel Slag

Procedia Environmental Sciences, 2012
AbstractThe current utilization rate of steel slag is only 22% in china, far behind the developed countries. At present, the amount of slag deposited in storage yard adds up to 30Mt, leading to the occupation of farm land and serious pollution to the environment. Improving the slag utilization is an important way to resolve these problems. The physical

Properties of steel slag aggregate and steel slag asphalt concrete

2010
Ferrous slags (blast furnace slag, steel slag, ferro-alloy, etc.) are the industrial byproducts from a greatest interest to the pavement construction industry, given their wide availability and scope of uses. Above that the production of aggregate from slag instead from rock would decrease the amount of raw material exploitation and enable further ...

Slag, steel and greenhouse gases

Revue de Métallurgie, 2002
A steel mill is a logistical hub, where iron units, by-products and effluents such as CO 2 compete in terms of volume. The problematics of greenhouse gas emissions will probably strengthen these transversal relationships. For example, blast furnace slag, which is a prime secondary material for the cement industry, substitutes for CO 2 intensive raw ...

Geopolymer Steel Slag Brick

Applied Mechanics and Materials, 2015
Steel slag waste is a by-product of steel mining industry. Effort to utilize the steel slag in concrete production has been failed due to its high contents of MgO which causes volumetric instability of the hardened concrete. Researchers also have failed to utilize the steel slag in the sub-base of road construction due to its low compaction ratio ...

Activity index for steel slag

Magazine of Concrete Research, 2011
Currently, most steel slag is used as aggregate for concrete, asphaltic paving and road bases. High-alkalinity steel slag shows certain cementitious properties and should be given priority to be used as a supplementary cementitious material in concrete, based on economical and environmental considerations.

Research on Performance of Steel Slag and Porous Cement Concrete Made by Steel Slag Aggregate

Advanced Materials Research, 2011
Porous cement concrete, which has some superiority in environmental protection compared with normal concrete, has been more widely applied. Performance of Steel Slag and influence of the steel slag aggregate on physical and mechanical properties and durability of porous cement concrete were studied in this paper.

Corrosion of Steel in Slag Concrete

"SP-199: Seventh CANMET/ACI International Conference on Fly Ash, Silica Fume, Slag and Natural Pozzolans in Concrete", 2001
Corrosion of reinforcement embedded in concrete is the most common cause of failure in concrete structures. The work is being carried out to investigate the rate and amount of corrosion of steel in concrete where cement is replaced by slag in different proportions.
