Jul 01, 1991  Vol. 21, No. 4 REMANENT MAGNETISM, CONCRETE 495 Conclusion Portland cement concrete cast in the laboratory became magnetized roughly parallel to the ambient (earth's) magnetic field. Since earlier tests conducted on cement paste and mortar showed that these materials acquire a magnetization during the casting process, it is believed that the ...

10%  Blast furnace slag admixtures also add to the enhancement of the intensity of remanence. The magnetization of Portland-cement-based materials shows a near linear relationship with the water /cement (w/c) ratios employed in the experimental work; the w/c ratios range between 0.2 – 0.6 in pastes and 0.3 – 0.6 in mortar.
