copper slag, in amounts of 20, 40, 60, 80, and 100 percent, was substituted for fine aggregate in cement mortar and concrete. the fineness modulus of the combination of copper slag and fine aggregate was roughly 2.6, the optimum fineness modulus for concrete mix design.

abstract this work focuses on the use of copper slag, as a partial replacement of sand for use in cement concrete and building construction. cement mortar mixtures prepared with fine aggregate made up of different proportions of copper slag and sand were tested
portion of copper slag is widely used in the sand blasting and in the manufacturing of abrasive tools, the remainder is disposed of without any further reuse or reclamation. the use of copper slag in the concrete as a replacement for fine aggregate, reduces the
pdf this paper is about the experimental study of the replacement of copper slag for fine aggregate in concrete. in this study, m40 grade concrete was considered to study the strength of concrete developed for the curing period of 7 days, 14 days and 28 days. in
concrete mixtures with different proportions of copper slag used as a partial or full substitute for fine aggregates were prepared in order to investigate the effect of copper slag substitution on the strength and durability of normal concrete. eight concrete mixtures were
slag, aka ground granulated blast furnace slag ggbfs is used as a supplementary cementitious material. it can be used ot replace some of the portland cement in concrete. it can help to make economical concrete of exceptional quality. it can decrease the exothermically produced temperature rise in large sections.
when sand is replaced with copper slag beyond 40% the strength of concrete was reduced and least compressive strength of 87.18 mpa is obtained when sand is replaced with 100% copper slag because the low water absorption properties of copper slag can leave excess water in concrete, which can cause excessive bleeding at higher copper slag content.
"for light polishing, we use a 2 1 ratio of ketchup and fine salt stirred into a paste and applied uniformly. it’s important to note the ingredients in your salt; common table salts and even some putatively “pure” culinary salts contain anti-caking agents (especially silicates) that can scratch copper.
use of copper slag as a replacement for fine aggregate in reinforced concrete slender columns a. s. alnuaimi department of civil and architectural engineering, sultan qaboos university, oman abstract the use of copper slag as a replacement for fine aggregate
affecting the durability properties of concrete. copper slag can be used as a potential alternative to coarse aggregate/fine aggregate used in concrete and mortars r r chavan and d b kulkarni 2013 has investigated the performance of high strength concrete hsc made with copper slag as a fine aggregate at
pdf this paper presents the experimental results of an ongoing project to produce concrete with copper slag as a fine aggregate. sustainability and resource efficiency are becoming increasing important issues. here the potential use of granulated copper slag, a
use of copper slag as a replacement for fine aggregate is investigated. three slender reinforced concrete columns of 150x150x2500mm were tested for monotonic axial compression load until failure. the concrete mix included ordinary portland cement, fine aggregate, 10mm coarse aggregate and copper slag. the ratios of copper slag to fine aggregate were 0%, 40% and 80%.
in this experiment a step is taken to reduce the use of fine aggregate in the concrete with copper slag. the fine aggregate is partially replaced with copper slag for 10%, 20%, 30%, 40% and 50%.
utilization of high volume copper slag (cs) in concrete is the aim of present work. this study leads towards cleaner production; by utilizing industrial waste i.e. cs. the objective of the present paper is to make high strength concrete (hsc) by utilizing cs as fine aggregate (f.a.). the work was carried in two phases.
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.
affecting the durability properties of concrete. copper slag can be used as a potential alternative to coarse aggregate/fine aggregate used in concrete and mortars r r chavan and d b kulkarni 2013 has investigated the performance of high
of 20 mm down size is used.fine aggregates used for normal concrete were natural river sand and copper slag. copper slag is procured from mythri metallizing india company, bangalore, karnataka, india.the physical and chemical of fine aggregates are shown in table.1.and table.2.
request pdf on researchgate concrete with copper slag fine aggregate. copper slag is a by-product yielded from a copper refinery. the annual amount of copper slag in japan is two million tons.
1 cost of concrete production is reduced when copper slag is used as a fine aggregate in concrete. 2 high toughness of copper slag contributes to increased compressive strength. 3 due to low water absorption and due to glassy surface of copper slag the
it was noticed that the use of copper slag as fine aggregate could greatly increase the abrasion resistance of the cement mortar (tang et al., 2000). hwang and laiw (1989) evaluated the compressive strength development of mortars and concrete containing fine copper slag aggregate with different water to cement ratios (fig. 4, fig. 5).
