requirements and guidelines on steel slag expansivity to further the use of appropriate quality steel slags, with demonstrated acceptable performance, in aggregate and ... shown in Figure 1 are divided into three broad areas: use as granular .... For slag used in a rigid matrix (portland cement concrete for .

Asphalt Concrete Aggregate, Granular Base, and Embankment or Fill. The use of steel slag as an aggregate is considered a standard practice in many jurisdictions, with applications that include its use in granular base, embankments, engineered fill, highway shoulders, and hot mix asphalt pavement.

Aug 08, 2007· All of their byproduct, steel slag, is dumped randomly in open areas, causing many environmentally hazardous problems. This research was intended to study the effectiveness of using steel slag aggregate (SSA) in improving the engineering .

The influence of steel slag was evaluated in concrete in this study and the following findings are concluded : • The aggregate produced from cooled steel slag meets criteria for the use in concrete mixes • Furthermore, According to ASTM D5106 experiments, steel slag meets the requirements to be used in concrete .

USE OF GRANULATED BLAST FURNACE SLAG AS FINE AGGREGATE IN CEMENT MORTAR M C Nataraja1*, P G Dileep Kumar2, A S Manu1 and M C Sanjay1 This paper investigates the possibility of utilizing Granulated Blast Furnace Slag (GBFS) as a sand substitute in cement mortar, in order to reduce environmental problems related to aggregate mining and waste disposal.

aggregate in concrete. The use of steel slag as coarse aggregate to reduces the need of conventional coarse aggregate in concrete. Environmental and Economic reasons have led to rapid development of slag utilization. Using steel slag as coarse aggregate to reduce the cost of the concrete production. 2. MATERIAL USED Cement

Utilizing steel slag for concrete construction has proved to be useful in solving some of the problems encountered in the concrete industry. Steel slag has been used in conventional concrete to improve the mechanical, physical, and chemical properties of concrete, as shown herein. Furthermore, the use of slag in concrete as coarse aggregate would minimize the accumulation of slag wastes and reduce the .

Using steel slag as both fine and coarse aggregate must be an efficient way with high additional value if possible because of the high percentage at 70~80% of aggregate in cement concrete [5]. Comparing with other approaches of using slag in concrete, such as using as cement admixture or mineral admixtures, the consumption of slag will

oxides and silicon dioxides. One of the most beneficial uses for furnace slag is in concrete. Because of its chemical and physical properties, it is a very reactive aggregate. Concrete containing slag can have very high strength and can be very durable. So Slag is can be used in concrete. When it .

concrete. Results concluded that the use of the steel slag as fine aggregate had a negative impact on the workability of concrete, but it had positive effect on mechanical properties, and the best results of compressive strength were obtained as the steel slag content was 15% and 30%. The steel slag aggregate produced by a steel plant is also utilized in asphalt concrete.

study has been conducted to explore the possibility of utilization of steel slag in concrete as coarse aggregate. After collection of steel slag aggregate from a local steel manufacturing company, the steel slag aggregate was separated into lightweight (SL), heavyweight (SH), and mixed (SM) slag aggregates. The

fine aggregates in concrete production [11], [12] and [13]. In Nigeria, steel is mainly produced from smelting of scrap metals and hundreds of tonnes of steel slag are produced every year. Approximately 96 to 145 million metric tons of steel slag are produced yearly [14]. .

In the C2 type, however, concrete strength and durability characteristics were better than those in the C1 type. It was concluded that the nongroundgranulated blastfurnace slag can be used as fine aggregate under some conditions.

This report showcases important studies conducted on use of steel slag as fine aggregate and its effect on the strength, durability, fresh density, workability etc of the resulting mix. A brief discussion on the properties and present uses of steel slag has been incorporated. Index Words –Aggregate, Concrete, Fine aggregate, Steel slag.

Apr 18, 2015· Slag is a by product of metal smelting and hundreds of tons of it are produced every year all over the world in the process of refining metals and making alloys.

by cement and 25% of stainless steel slag by fine aggregate and of coarse aggregate. The stainless steel slag concrete made with the optimum strength gained replacements. The strength of the stainless steel slag concrete at an age of 7 days 14 days and 28 days are more than the conventional concrete.

At the long age of 91 days, the compressive strength of concrete using slag fine aggregate exceed the concrete using river sand when watercement ratio was greater than 30%. The compressive strength of concrete using granulated blast furnace slag as fine aggregate can exceed 80N/mm2, the granulated blast furnace slag can be used in highstrength concrete.
