In a new scientific achievement, Assistant Instructor Engineer Saif Saad Mansour, a researcher at the Upper Euphrates Center for Sustainable Development Research at the University of Anbar, was able, in conjunction with a group of researchers, to publish a scientific research in the Journal of King Saud University - Engineering Sciences, a sober international scientific journal within the first quarter Q1 (which has a citation score of 12.1): By searching tagged:
(Effectiveness of replacing cement partially with waste brick powder in mortar)
The researchers participating in the research (Assistant Instructor Saif Saad Mansour, Assistant Professor Dr. Shilan Mahmoud Hama, Assistant Instructor Difaf Natiq Hamdallah).
The research revolves around the possibility of replacing cement powder partially and for different reasons, where three sets of tests were carried out: fresh, mechanical and permeability properties. Eight mixtures with different proportions of replacement ratios are as follows: 10, 15, 20, 25, 30, 35, 40, and 50%. In addition to the reference mixture without powder substitutes, the pilot programs include three sets of tests: fresh properties (flow test and fresh density), mechanical properties (dry density, compressive strength, bending strength), and transport properties (water absorption ratio, water absorption rate, i.e. absorption, and percentage of jet voids). An ultrasonic speed pulse test was also performed. The fluidity and density of fresh mixtures decreases linearly with increasing the amount of WBP of the water/fixed binder ratio. However, the density of the hardened state was found to be slightly higher than that of the reference mixture for mixtures containing brick powder by up to 20%. The results indicate that the strengths of mixtures containing WBP are higher than those of the control mixture. The highest strength in the mixture was tested at 15% WBP for both the compressive and tensile forces of the samples. In general, brick powder reduced the slurry's ability to transport liquid, as was evident from the permeability test results.
