Abstract
There are few
studies on this problem and they take the same directions as external
researches. These studies are aimed at finding the properties of
local slag, and its effects on concrete properties.
Local slag is produced by Electrical
Arc Furnace using scrap as raw material, for production of pig iron and slag.
This slag is called (Steel Slag).Local slag has low
activity as a Cementitious material, because it has low content of glass .As a
result local slag is left without any treatment. Besides local slag has high
content of iron. For these reasons, this study is
carried out to investigate the use of iron industry by-products in concrete, as
partial replacement of gravel. The study included slag effects on concrete
properties namely slump, compressive strength, tensile strength, and shrinkage.
One set of experiments was carried out. This set deals with the effects of replacement of coarse
aggregate by slag with the following percentages (0،30,60)% at
ordinary temperature . Generally, the result of the this set
of experiments show, reduction in workability, Improvement compressive
strength, tensile strength, reduction in shrinkage .
