Method for preparing quick-setting cement from waste bricks and tiles
The invention relates to a method for preparing quick-setting cement from waste bricks and tiles, belongs to the field of building materials, and aims to accelerate the initial setting speed of cement by using waste brick and tile powder as a raw material and using a composite enhancer to generate a combined action between the composite enhancer and a mixed raw material during quick-setting cement watering construction, so thatthe initial setting speed of the cement can be accelerated, and under the combined action of caustic soda, an expanding agent, a tackifying water-retaining agent and the like, the initial setting speed is less than 3 minutes, the final setting speed is less than 8 minutes, and the prepared quick-setting cement is low in resilience and high in strength after final setting. The construction requirements of the quick-setting cement can be completely met.
本发明涉及一种用废弃砖瓦制造速凝水泥的方法，属于建筑材料领域，本发明以废砖瓦粉为原料，通过使用复合强化剂，在速凝水泥掺水施工时，复合强化剂与混合原料之间产生联合作用，能加速水泥的初凝速度，在苛性钠和膨胀剂、增粘保水剂等的共同作用下，初凝速度小于3分钟，终凝速度小于8分钟，且所制备出的速凝水泥，终凝后回弹低，强度高。能完全满足速凝水泥的施工需求。
