Method for preparing anti-radiation sulphoaluminate cementing material from lead-zinc tailings and aluminum ash
The invention relates to a method for preparing an anti-radiation sulphoaluminate cementing material from lead-zinc tailings and aluminum ash, and belongs to the field of special building materials and solid waste resource utilization. The method for preparing the anti-radiation sulphoaluminate cementing material by using the lead-zinc tailings and the aluminum ash comprises the following steps: step 1, weighing 3-20% by mass of the lead-zinc tailings, 5-15% by mass of an aluminum ash raw material, 50-70% by mass of limestone and 5-20% by mass of industrial byproduct gypsum, mixing and grinding to obtain a raw material of the anti-radiation sulphoaluminate cementing material; 2, calcining the anti-radiation cementing material raw material at the temperature of 1250-1450 DEG C for 30-60 minutes, and rapidly cooling to obtain an anti-radiation sulphoaluminate cementing material clinker; and 3, weighing 95-99% by mass of the anti-radiation cementing material clinker and 1-5% by mass of a mixed additive, grinding and uniformly mixing to obtain the anti-radiation sulphoaluminate cementing material. According to the method for preparing the anti-radiation cementing material from the lead-containing solid waste, the prepared cementing material has a good anti-radiation effect while having a good mechanical property, and has a wide application prospect in special fields such as high radiation and the like.
