Containing copper slag as partial replacement of fine aggregate in concrete the present study is based on trial mixes and achieving target strength. mix proportions have been obtained for m30 grade concrete. then copper slag is replaced by 0, 10, 20, 30, and 40 by the mass of fine aggregate to study the above tests.

Copper slag also has a high strengthtoweight ratio, making it an effective option in concrete, or as a fill material under the roadway. some studies were carried out using grained copper slag as fine aggregate and fine powder copper slag for partial replacement of cement.

Copper slag as partial replacement of aggregate to control the amount of bleeding to less than 5 lm. 2. studies by alnuaimi indicated that replac2005 ement of fine aggregate (sand) by copper slag does not have an adverse effect on the load carrying capacity of the concrete columns. rojas 2008 had reported that copper slag exhibits.

Copper slag by replacing natural fine aggregate at different percentage like (0, 20, 40, 60, 80, and 100). b. objective of the investigation 1) the use of copper slag in the concrete as a replacement for fine aggregate, reduces the costs of disposal, lowers the cost of the concrete and also helps in protecting the environment.

Copper slag is one of the materials that is considered as a industrial waste which can be used in construction industry. this paper presents the results of an experimental investigation on the properties of concrete using copper slag as partial replacement of fine aggregate.

Copper slag possesses mechanical and chemical characteristics that qualify the material to be used in concrete as a partial replacement as fine aggregate. the properties of . copper slag listed in table 3.4 . table 3.4 . properties of copper slag . description result . 1 specific gravity 3.63 2 water absorption () 3.4 . fig. 3.1 copper slag.

Copper slag. fig.7. comparison of flexural strength of beam iv. conclusion the concrete was prepared for the m 25 grade concrete with partial replacement of fine aggregate by copper slag with various percentages of 0, 10, 15 and 20. the specimens were casted for 7days, 14 days and 28 days then tested. the results are presented above.

Copper slag:copper slag is a industrial waste obtained from smelting and refining process of copper from strelite industry. the copper slag is a black glassy particle and granular in nature and has a similar particle size range like sand. in this project, copper slag is use in replacement of fine aggregate in various percentages. the.

Cupola slag is underutilized and very few studies are documented in literature wherein cupola slag has been utilized in concrete production. an attempt has been made to examine the effectiveness of cupola slag, as a partial substitute to fine aggregates, on the mechanical and durability properties of concrete. fine aggregate was replaced by.

Decreased as copper slag content increases up to 50 replacement. 3. materials used . in the present investigation materials used are: 1) ordinary portland cement 53 grade 2) fly ash as partial replacement to cement. 3) copper slag as partial replacement to sand 4) naturally available river sand as fine aggregate.

The main objective of this study was to investigate the effect of using copper slag as a partial andor full replacement for sand in mortars and normal concrete. the study consisted of the following tasks: 1. investigate the effect of copper slag replacement as a fine aggregate on the compressive strength of cement mortars at different curing.

From 50 to 100 replacement .replacement of copper slag in fine aggregate reduces the cost of making concrete. a. objective: in this study the properties of concrete like workability, compacting factor compressive strength, are found out for partial replacement of fine aggregate with copper slag. iii. material and work:.

In this study, partial replacement of cement with ggbs and sand with copper slag considered. experimental study is conducted to evaluate the workability and strength characteristics of hardened concrete, properties of concrete have been assessed by partially replacing cement with ggbs, and sand with copper slag.

Increased by 34 at 20 replacement of fine aggregate with copper slag, and up to 80 replacement of copper slag, concrete gain more strength than normal concrete strength. the flexural strength of concrete found to be increased by 14 with 30 replacement of copper slag. 8 2. research objectives 1.
