Preparation method of phosphogypsum lightweight building block with low water cement ratio
The invention provides a preparation method of a low-water-cement-ratio phosphogypsum lightweight building block. The preparation method comprises the following steps: preparing ice particles according to an optimal water-cement mass ratio; preparing ardealite powder according to the mass of the ice particles, and uniformly mixing the ardealite powder with the ice particles; pouring the mixture of the ardealite powder and the ice particles into a mold, and compacting by a press machine; after ice particles are melted and phosphogypsum is initially set, demolding is performed; the low-water-cement-ratio phosphogypsum light building block is obtained through the steps. The ardealite block or strip block can be prepared under the optimal water content condition, it is guaranteed that ardealite is fully hydrated, the strength meets the requirement, and the problem of ardealite cracking caused by excessive water is avoided. The hollow volume can be estimated according to the number of added ice particles, the hollow rate of the phosphogypsum building block or strip block is freely controlled, a light product is prepared, the use amount of raw materials is reduced, and the phosphogypsum block or strip block can be used for wall filling and heat insulation.
本发明提供一种低水灰比磷石膏轻质砌块的制备方法，包括以下步骤：按最优水灰质量比制备冰粒；根据冰粒的质量并准备磷石膏粉，将磷石膏粉与冰粒混合均匀；将磷石膏粉与冰粒混合物倒入模具，压力机压实；待冰粒融化，磷石膏初凝后脱模；通过以上步骤得到低水灰比磷石膏轻质砌块。能够实现最优含水量条件下制备磷石膏砌块或条块，保证磷石膏水化充分，且强度满足要求，避免多余水分造成磷石膏开裂问题。能够通过添加的冰粒数量，估算出空心体积，自由控制磷石膏砌块或条块的空心率，制备出轻质的产品，减少了原材料用量，能够用于墙体填充隔热。
