Properties And Effects Of Copper Slag In Concrete<br>
<br>

<strong>Abstract</strong><br>
Copper slag is a by-product  obtained during matte smelting and refining of copper. This  work   reports   an  
experimental  procedure  to  investigate  the  effect  of  using  CS   as  partial  replacement  of  sand. Six  series  of  concrete  
mixtures  were  prepared  with  different  proportions  of  CS   ranging  from  0%  to  100%.  The  test  results  of  concrete  
were   obtained   by   adding   CS    to   sand   in   various percentages ranging from   0% to   100%.  
All specimens were cured for 7, 28, 56 days before compression strength test. The results indicate that Compressive strength 
and flexural Strength is increased due to high toughness of copper slag.
