| dc.description.abstract | Cement is the main material in concrete that helps everything stick together.
However, it is also one of the biggest sources of carbon dioxide (CO₂), which is
harmful to the environment. Because of this, researchers are trying to replace
cement with more eco-friendly materials. In this study, waste slag from a steel
cutting house called Venus sign limited was used as a partial replacement for
cement. A well-established scientific explanation in Civil Engineering and
Materials Science is known as the “Pozzolanic Reaction. Initial tests showed that
this slag can behave like a pozzolanic material, which means it can help in
strength development.
The slag was first ground into fine particles that could pass through a #100 sieve.
Concrete samples were then prepared by replacing 10%, 20%, and 30% of cement
with slag, using water–cement ratios of 0.40 and 0.45. Compressive strength tests
were conducted at 7 and 28 days. The results showed that when 10% slag was
used, the strength slightly decreased compared to normal concrete. However,
when 20% and 30% slag were used, the strength decreased further. | en_US |
