Aug 20, 2018· From Table 6 it is observed that chloride ion permeability for conventional concrete is low to moderate, whereas for concrete with copper slag as the fine aggregate is moderate as per ASTM C 1202. The observed results in the present studies show that application of CS does not significantly change the RCPT values.
from 50 % to 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:
Feb 01, 2011· To study the effect of copper slag substitution as a replacement for fine aggregates on the strength of cement mortars, specimens were prepared with different percentages of copper slag (by weight). The percentages of copper slag added were as follows: 0% (for the control mix), 20%, 40%, 50%, 60%, 80%, and .
An experimental investigation was conducted to study the effect of using copper slag as a fine aggregate on the properties of cement mortars and concrete. Various mortar and concrete mixtures were prepared with different proportions of copper slag ranging from 0% (for the control mixture) to as fine aggregates replacement.
pavement, while copper tresses aslag and zinc slag may be used as a partial replace ment of fine aggregate for the construc-tion of sub base, base and bituminous layers. The specific gravity of copper slag, zinc slag and steel slag varied in the range of 2.75 – 3.6[5] Kajal et al (2007) Study present the use of waste plastic and copper slag ...
Some properties of a typical copper slag are shown in Table I, and it can be observed that air-cooled copper slag has a black colour and glassy appearance. The specific gravity varies with iron content, from 2.8 to 3.8. The unit weight of copper slag is somewhat higher than that of conventional aggregate. The absorption capacity of the
The present study mainly focuses on investigating the effect of using copper slag as a replacement of fine aggregate on the strength properties. In this report, M25 grade concrete was used and tests were conducted for various proportions of copper slag replacement with …
