More Information
Summary:The invention provides a high-performance lightweight aggregate for lightweight ultrahigh-performance concrete and a preparation method of the high-performance lightweight aggregate. The aggregate comprises the following components in percentage by weight: 30-40% of copper tailing slag, 25-35% of lithium slag, 10-20% of red mud, 5-15% of pyrite cinder, 3-8% of titanium slag, 1-3% of calcium carbonate and 1-3% of magnesium carbonate. The invention further discloses a preparation method of the high-performance light aggregate for the light ultra-high-performance concrete, and the high-performance light aggregate is prepared from the industrial solid waste copper tailings, the lithium slag, the red mud, the pyrite cinder, the titanium slag, the calcium carbonate and the magnesium carbonate through the procedures of drying, uniform mixing, grinding, pelleting, aging, balling, high-temperature firing and the like. And when the material is applied to lightweight ultra-high performance concrete, the strength, the vo
