blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected. Close to half of the coarse aggregates used in portland cement concrete in North America are gravels

Copper Slag (CS) is produced as waste from roasting of copper, in which sulphur (as SO 2 ) is eliminated. CS was used as fine aggregate (up to 30%) in the design of bituminous mixes like Bituminous Macadam, Dense Bituminous Macadam. Bituminous Concrete and Semi-Dense Bituminous Concrete. Mechanical properties of mix such as Marshall stability, Indirect Tensile Strength was determined. and water absorption rates were observed. The latter paper used CEM-I cement and considered both coarse aggregates replacement by air cooled copper slag at 20 and 40% vol-ume replacements as well as fine aggregate replacement by copper slag at 20 and 40% levels per volume. It studied gas permeability of copper slag concrete (which was sig-

sile strengths of concrete specimens made with copper slag as fine and coarse aggregates are almost the same as that of nor-mal concrete or even significantly more than control mixtures Caliskan, 2004, Ayano, 2004, Hwang, 1989, Shoya, 2003. It was noticed that the use of copper slag as fine aggregate could greatly increase the abrasion ... study the potential use of copper slag as fine aggregate on the strength of both normal and high strength concrete. Concrete mixtures were prepared using different proportions of copper slag as partial and full replacement of fine aggregate. The percentage of copper slag added by weight ranged between 10-100% of sand used in concrete.

III. MATERIAL CHARACTERISATION 4.1 Aggregates The fine aggregate used for the study is manufactured sand. The coarse aggregates were of 12mm and 20mm size. Tests were carried out on fine aggregate and coarse aggregate in-order to obtain their physical properties.

PDF Use of copper slag as construction material in

2. Fine aggregate Two types of fine aggregates are used a) Steel slag as received from the factory without any screening b) Silica sand of natural resources known locally as desert sand. Sieve analysis was carried out on both the natural sand and the fine slag according to ASTM C33.Specific gravity and M-25and M-30 grade of concrete. Here the fine aggregate partially replaced with copper slag in concrete with 5%, 10%, 15% 20% by weight of fine aggregates and cement Mix design was prepared for M-25 and M-30 grade of concrete by replacement of copper slag as fine aggregate and cement. We

Use of Steel Slag in Concrete as Fine Aggregate

Abstract. The use of copper slag as a replacement for fine aggregate in construction will reduce damage to the environment due to the waste resulting from the copper manufacturing process and help in saving natural resources. In this research, the use of copper slag as a replacement for fine aggregate is investigated. per IS 383 provisions were used as fine aggregates. Specific gravity 2.85 Fineness modulus 2.79 Referring to 600 micron sieve, the percentage passing is 58.00 % which confirm that fine aggregate belongs to Zone II as per Is 383-1970.

were 41.53 N/mm2, 3.86 N/mm2 and 5.42 N/mm2 for 40% replacement of fine aggregate by copper slag as compared to control mixture. The ultrasonic pulse velocity test indicated the excellent quality of concrete at all percentage replacement level. Therefore, it is recommended that 40% of copper slag can be use as replacement of fine aggregates. Slag is composed of calcium oxide (CaO), silica (SiO2) and alumina (Al203). Slag is pulverized into a fine powder called ground granulated blast furnace slag and is used in this form as a cementitious component of concrete. D. Fly Ash Fly ash is the most widely used pozzolan in concrete. It is a fine

information obtained from tests used to measure the aggregates quality or, more importantly, its service record, or both. More performance tests are also used to test aggregates in concrete. A typical consensus specification for fine and coarse aggregate for concrete is ASTM C 33. Synthetic aggregates may be either byproducts of an industrial 2001 by slag cement manufacturers and the Slag Cement Association, the American Concrete Institute officially reviewed and changed the terminology from GGBFS to slag cement (ACI Committee 233, 2004). The term slag cement will be used throughout this paper when referring to finely-ground granulated blast-furnace slag.

Use of Steel Slag as an Alternative to Aggregate and

Steel slag aggregates are already being used as aggregates in asphalt paving road mixes due to their mechanical strength, stiffness, porosity, wear resistance and water absorption capacity. C 1.1. Ground Granulated Blast-Furnace Slag Its Chemistry and Use with Chemical Admixtures Paper by Grace Construction and Product Company 1 found that The results are presented above. The optimum value which provided the best performance was at 50% addition of copper slag for compressive strength.
