Use of Blast Furnace Slag Aggregate in Concrete Hiraskar and Chetan Patil AbstractThe Iron industries produce a huge quantity of blast furnace slag as by–product, which is a non–biodegradable waste material from that only a small percentage of it is used by cement industries to manufacture cement.
Phosphorus Slag. Phosphorus slag has been used as an aggregate substitute in hot mix asphalt, as a lightweight masonry aggregate, and as cement kiln feed. Granulated phosphorus slag has also been used experimentally in the production of a blended cement product. (4) Lead, LeadZinc, and Zinc Slags
In the Australian concrete industry context, the term ''slag'' generally refers to ground, granulated, iron blast furnace slag – with the descriptors to be explained and developed in this technical note. In a general sense, the term ''slag'' refers to a waste material separated from metals during the smelting or refining of an ore in a
Once the slag has been cooled and ground to a usable fineness it is stored and shipped to suppliers throughout the United States. Slag cement is commonly found in readymixed concrete, precast concrete, masonry, soil cement and high temperature resistant building products.
though sodium slag contains lead (approximately 5 wt. %), soluble alkalis and decomposes in contact with air, Na2CO3 is mainly used in industry due to generated amount of total slag, as well as reduced energy and gas consumption [4]. Secondary lead slag is characterized as hazardous waste in European Waste Catalogue due to content of

This paper reports the findings from a laboratory evaluation of a metallurgical slag as a pozzolanic admixture for concrete. Lead blastfurnace slag is fumed in a batch process to remove base metal values after which the molten barren slag is waterquenched to produce a glassy, granular product.
challenging. Utilizing steel slag in concrete mixes has proved to be useful in solving some of the problems encountered in the concrete industry. Steel slag was used in conventional concrete to improve its mechanical, physical, and chemical properties. Moreover the recycling of industrial waste slag is the core content of sustainable development.
Steel slag in powder or granular form is used in construction for concrete and asphalt roads, fertilizer, and cement blocks for harbors to stop the tide. In the concrete industry there is research to develop a cheaper, stronger, and more durable structure.

The optimum mixture proportions for ternary blends, as with other concrete, will be dependent on the final use of the concrete, construction requirements and seasonal considerations. In low W/CM applications such as paving, mixtures with 15 percent fly ash and 30 percent slag cement component have been used successfully.
A nonferrous slag from the production of metallic zinc was studied as a new ingredient for concrete. It was used in two forms: ground and unground material. The ground slag replaced 15% of portland cement, whereas the unground slag replaced 20% of the natural sand.
appliions. For years the construction industry has used ground granulated blast furnace slag (GGBFS) as a replacement for ordinary portland concrete cement (OPC) to lower curing temperatures. However, MoDOT specifiions only allowed low levels of blast furnace slag in concrete mixes. Get price
