ملخص البحث
The research presents a study on the possibility of using natural stone saw powder in the West Bank, which is considered an environmental problem and brings agricultural land pollution. This study examines the possibility of using the powder waste in the Portland lime cement industry to reduce the cost as well as the environmental damage resulting from the cement industry, where different proportions of powder were added on clinker and the effect on the physical and mechanical properties was studied. The results demonstrate that the compressive strength of different mixtures after 28 days slightly decreased upon the addition of 5 wt %, 10 wt. % and 15 wt. % limestone powder in comparison with reference sample without powder, though strength of mixtures complies with standard (EN-197-1-2011) limits for the limestone cement, the percentage of consistency of the prepared samples decreased from 29.5% to 29.0% upon the addition of limestone powder, while both of the initial and final setting times of the prepared samples decreased with the addition of limestone powder, the initial setting time decreased around 35 minutes while the final setting time decreased 30 minutes the addition of limestone powders up to 15 wt. %. The adding powder did not affect negatively on the expansion value of the cement samples, and it had a value of 1.0 mm for all tested samples, which is an acceptable value according to EN-197-1-2011, and the results obtained mean the possibility of using stone saw powder in a positive way in the manufacture of Portland lime cement, thus solving the environmental problem resulting from the stone industry, as well as reducing the cost of cement and the damage of its manufacture on the environment resulting from the stone industry, as well as reducing the cost of cement and the damage of its manufacture on the environment (global warming). © 2024 by authors, all rights reserved.
