Morphology characteristics of mix aggregates with crushed air-cooled blast furnace slag (SCR) and crushed limestone (LCR) with 5–20 mm and 20–40 mm gradation were represented by numerical parameters including angularity number (AN) and index of aggregate particle shape and texture (IAPST). The effect of mix aggregates containing …
Some of the important properties of the steel slag and crushed limestone aggregates are summarized in Table 4. 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.

When crushed and sized properly, slag can be sold and used as valuable material in many different ways, for example, as aggregates. However, since slag usually contains uncrushable objects, it is typically considered a challenging feed material for conventional jaw crushers. Uncrushable objects in feed
in granular, glassy aggregates. This slag is crushed, pulverised and screened for use in various applications, particularly in cement production because of its pozzolanic characteristics. Steel plants utilise cold slag for internal consumption and also for outside sale. The slag after cooling is crushed and used as road metal and
During the blast furnace process limestone (CaCO 3) flux is added, to collect the waste products produced: silica (SiO 2), phosphorus pentoxide (P 2 O 5), calcium sulfide (CaS), magnesia (MgO) and alumina (Al 2 O 3).This forms blast furnace (BF) slag, which floats on top of the surface of the hot metal (Peters, 1982).The blast furnace is …
Abstract. Steel slag (SS) is regarded as a potentially promising alternative material for road construction, which could ameliorate the shortage of high-quality …

This research study was conducted to evaluate the mechanical properties and durability characteristics of steel slag aggregate concrete in comparison with the crushed …
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.
Properties of Crushed Concrete. Crushed concrete is known for its high compressive strength, making it a durable and long-lasting material. It also has good drainage properties, making it suitable for use in drainage systems and as a base for roads and driveways. ... However, it is important to note that the properties of slag can vary ...
Figures 5 and 6 show the influences of crushed stone content on CBR and resilient modulus of the studied mixtures. As shown in Figs. 5 and 6, the S0.7C0.3 with crushed stone content of 30% produced the highest values in both CBR and resilient modulus of the mixtures, although the lowest porosity was observed at crushed stone …
Steel slag is a by-product of the steel industry and usually contains a high amount of f-CaO and f-MgO, which will result in serious soundness problems once used as a binding material and/or aggregates. To relieve this negative effect, carbonation treatment was believed to be one of the available and reliable methods. By carbonation treatment …
1. Introduction. Current means of handling sewage sludge (landfills, fertilizer, incineration) are becoming less attractive due to changing regulations and concerns about pollution [[1], [2], [3]].Moreover, sewage sludge disposal has a high cost [4] (from 50 to 120 € per ton [4]).Since it is a "renewable" feedstock and has a calorific value comparable to …
