【 摘 要 】

The study about the unburned brick of electrolytic manganese slag had become the research focus because of the large amount of manganese slag and the lower cost of making bricks. The effect of aggregate addition on the properties of unburned brick of electrolytic manganese slag as main material was studied. When the molding pressure was 2MPa, mixing water content was 25%, and the concent of aggregate was 30%, the compressive strength and flexural strength of electrolytic manganese brick were 11.36MPa and 2.92Mpa after 7 days, and those were 16.40MPa and 3.19MPa after 28 days, the volume density was 1.38g/cm3, the linear shrinkage rate was 0.938%, the water absorption rate was 30.52%, the saturation coefficient was 1.531, and there was no frost phenomenon.
