Component determination method of ammonia alkali white mud baking-free brick and preparation method of baking-free brick
The invention provides a component determination method of an ammonia alkali white mud baking-free brick and a preparation method of the baking-free brick, and belongs to the technical field of solid waste treatment.The component determination method comprises the steps that according to the pH value of ammonia alkali white mud, steel slag is used for modifying the ammonia alkali white mud; testing the water content omega 1 of the modified ammonia alkali white mud; the modified ammonia alkali white mud and the water consumption are determined, the modified ammonia alkali white mud X is equal to 20/(1-omega1)-40/(1-omega1) parts, and the water Y is equal to (20-omega1X)-(50-omega1X); and calculating Y-omega1X according to the water content of the modified ammonia alkali white mud. The preparation method of the baking-free brick comprises the following steps: stirring mineral powder, fly ash, modified ammonia alkali white mud and water according to a mass ratio to obtain slurry; adding slag and aggregate into the slurry according to a mass ratio, and stirring to obtain a green brick wet material; putting the green brick wet material into vibration compression molding equipment, and performing compression molding to obtain a molded green brick; and demolding the molded green brick, and curing to a specified age to obtain the ammonia alkali white mud baking-free brick. The baking-free brick is prepared from the ammonia alkali white mud, the utilization rate of the ammonia alkali white mud is increased, and the prepared baking-free brick has good mechanical performance.
本发明提供了一种氨碱白泥免烧砖的组分确定方法及免烧砖的制备方法，属于固废处理技术领域，组分确定方法包括：根据氨碱白泥pH值，利用钢渣对其进行改性；测试改性氨碱白泥含水率ω1；确定改性氨碱白泥与用水量，改性氨碱白泥X＝20/(1‑ω1)～40/(1‑ω1)份，水Y＝(20‑ω1X)～(50‑ω1X)；根据改性氨碱白泥含水率，计算Y‑ω1X。免烧砖制备方法包括：将矿粉、粉煤灰、改性氨碱白泥、水按质量比例进行搅拌得到料浆；将炉渣、骨料按质量比例加入料浆中搅拌，得到砖坯湿料；将砖坯湿料放入振动压制成型设备，压制成型得到成型砖坯；将成型砖坯脱模后养护至规定龄期得到氨碱白泥免烧砖。利用氨碱白泥制备免烧砖，提升了氨碱白泥的利用率，且制备的免烧砖具有良好的机械性能。
