Concrete accelerator and preparation method thereof
The invention discloses a concrete accelerator and a preparation method thereof. The concrete accelerator comprises the following components in parts by weight: 50-60 parts of waste aluminum ash, 3-8parts by weight of bauxite, 15-25 parts by weight of sodium carbonate, 6-10 parts by weight of silicon powder, 6-10 parts by weight of quick lime and 2-6 parts by weight of a stabilizer. The preparation method of the concrete accelerator comprises the following steps: accurately weighing the raw components in proportion, and conveying a formed mixture to a rotary kiln through a conveying system for roasting. According to the invention, shorter initial setting time and final setting time are obtained through a unique formula; better compressive strength is realized; the waste aluminum ash is adopted in the formula, so waste utilization can be reasonably carried out; in the preparation process, waste gas, waste water and waste smoke are avoided; and in the preparation method, a rotary kiln is adopted for roasting the mixed raw materials, a kiln temperature is easy to control, and a unique roasting process is selected, so the performance of the concrete accelerator can be effectively improved.
本发明公开了混凝土速凝剂及其制备方法，混凝土速凝剂按重量份计包括废铝灰50‑60重量份；铝矾土3‑8重量份；纯碱15‑25重量份；硅粉6‑10重量份；生石灰6‑10重量份；稳定剂2‑6重量份；混凝土速凝剂的制备方法，包括将各原料组分按比例精确称量，之后将混合物经输送系统输送到旋窑进行焙烧。本申请通过独特的配方获得了更短的初凝和终凝时间；且具备更好的抗压强度；配方中采用到了废铝灰，能够合理的进行废物利用；本申请制备过程中做到了不出现废气、废水和废烟；本申请的制备方法中采用到旋窑进行混合原料的焙烧，窑温易控，且选用了独特的焙烧工艺，使得本申请能有效改善混凝土速凝剂的性能。
