Study on Preparing Aero-Concrete Using Leaching Residual Slag of Lepidolite Ore
Preparation technology and the performance of aero-concrete using leaching residual slag come from extracting lithium from lepidolite were discussed in this paper. Results show the strength of aero concrete can be slightly improved by using lithium slag instead of fly ash, but the volume density has a major increase, and the gas-forming speed doesn't match the thickening speed. By means of increase in aluminum content and the ratio of water to materials, adding the activating agent, excellent performance products that meet the national standards were synthesized.
