Using Mill-Rejected Granular Cement as a Replacement for Fine Aggregate
Abstract
Feseha Sahile Asrat and Tewodros Tekeste Ghebrab
This research study presents a report on the effect of mill-rejected coarse-grained cement on concrete properties when the cement is used as a partial replacement for fine aggregates. Concrete mixes containing 5%, 10%, 15%, and 20% replacement of natural sand with mill-rejected cement were prepared and tested for strength and permeability. The test results indicate that the strength of concrete increases and its permeability decreases with the increase in the amount of mill-rejected cement.
