Mineral admixture prepared through collaborative roasting of electrolytic manganese residues and coal gangue and application of mineral admixture
The invention discloses a mineral admixture prepared by collaborative roasting of electrolytic manganese residues and coal gangue and application of the mineral admixture. The mineral admixture is prepared from the following raw materials in parts by mass: 100 parts of electrolytic manganese residues and 80-160 parts of coal gangue; wherein the mass ratio of the coal gangue to the manganese slag is 0.8-1.6. The mineral admixture with higher activity is synthesized mainly based on the preparation method of reduction synergistic roasting according to the principle of solid waste synergistic recycling, the application targets of low-cost recycling of the electrolytic manganese residues and high value of the coal gangue are achieved, the defect that the resource utilization direction of the coal gangue is saturated is overcome, and the utilization rate of the coal gangue is increased. Compared with original electrolytic manganese residues and coal gangue, the synthesized composite mineral admixture has higher pozzolanic activity, the maximum 7-day compressive strength reaches 19.95 MPa, and the strength index is 68.65%; under the optimal condition, the maximum compressive strength can be increased by 55.98% and the maximum conductivity can be increased by 71.54% compared with the original components, so that the compressive strength can be increased by 55.98% and the maximum conductivity can be increased by 71.54%.
本发明公开了利用电解锰渣与煤矸石协同焙烧制备的矿物掺合料及其应用。矿物掺合料采由下述质量份原料组成：100份电解锰渣，80～160份煤矸石；其中，煤矸石和锰渣的质量比为0.8～1.6。本发明主要基于还原协同焙烧的制备方法，以固体废物协同资源化的原则来合成具有更高活性的矿物掺合料，实现电解锰渣低成本资源化以及煤矸石高值化的应用目标，弥补煤矸石资源化利用方向已饱和的缺点，相比于原始电解锰渣和煤矸石，所合成的复合矿物掺合料具有更高的火山灰活性，最大的7天抗压强度达到19.95MPa，强度指数为68.65%；最大的电导率达到212.38%，在最佳条件下，与原有的组分相比，抗压强度最大可提高55.98%，电导率可提升71.54%。
