Abstract
In this study, foam cement based absorbing materials was made by taking graphite and magnetic ferrite as electromagnetic wave absorbers. Effect of H2O2 content on dry density, compressive strength and porosity of the materials was studied through single factor experiment. The results show, with the H2O2 dosage increase from 5.0% to 9.0%, the dry density decreases and the porosity increases gradually. However the compressive strength appears to increases and then decreases. When the dosage of H2O2 is about 7.0%, the compressive strength, reached an extreme value, is about 2.91Mpa, the dry density is 706kg/m3 , and the porosity is 63.16% at the same time
