Gold tailing and multi-source solid waste cooperated sintered brick and preparation method thereof
The invention discloses a sintered brick prepared from gold tailings and multi-source solid wastes and a preparation method of the sintered brick. The sintered brick is prepared from the following components in parts by weight: 60-80 parts of sintered brick raw materials, 15-25 parts of a sintering aid and the balance of wastewater, the sintered brick is prepared from the following raw materials in parts by weight: 70-80 parts of gold tailings and 20-30 parts of ardealite, the sintering aid is prepared from the following components in parts by weight: 30 to 50 parts of fly ash, 20 to 40 parts of magnesium slag, 8 to 15 parts of waste glass powder and 10 to 18 parts of bentonite. The compressive strength of the prepared sintered brick is larger than or equal to 25 MPa, the volume density is smaller than 1750 kg/m < 3 >, the saturation coefficient is smaller than 0.74, the water absorption rate is smaller than 16%, the scumming phenomenon is avoided, the requirement for the strength grade of GB/T 5101-2017 sintered ordinary bricks MU25 is met, the method is easy to operate, low in cost and suitable for large-scale production, and the product has the advantages of being light, high in strength, environmentally friendly, low in carbon and high in tailing solid waste utilization rate.
本发明公开了一种黄金尾矿协同多源固废的烧结砖及其制备方法，所述黄金尾矿烧结砖按重量份数由以下组分组成：烧结砖原料60‑80份，烧结助剂15‑25份，余量为废水；所述烧结砖原料按重量份数计由以下组分组成：黄金尾矿70‑80份，磷石膏20‑30份；所述烧结助剂按重量份数计由以下组分组成：粉煤灰30‑50份，镁渣20‑40份，废玻璃粉8‑15份，膨润土10‑18份。本发明制备的烧结砖抗压强度≥25MPa，体积密度＜1750 kg/m3，饱和系数＜0.74，吸水率＜16%，无泛霜现象，满足GB/T 5101‑2017《烧结普通砖》MU25强度等级要求，该方法操作简单、成本低、适合规模化生产，制品具有轻质高强、绿色低碳、尾矿固废利用率高的特点。
