在胶结充填料的制备工艺中化学添加剂改善胶结充填料的工艺性质得到了发展。现已有在充填料组分中利用以木素磺酸盐和其它制剂为基础的空气吸附剂、增塑剂和表面活性物质的资料公诸于世。用表面活性物质化学添加剂的主要目的是提高强度增长速度,改善输送指标(对离析的稳定性),降低用水量,减少充填料的管 The technological properties of chemical additives to improve the cementitious filler have been developed in the process of preparing cemented filler. Information on air adsorbents, plasticizers and surface-active substances based on lignosulfonates and other formulations is now available in the filler components. The primary purpose of using surface active chemical additives is to increase the rate of strength increase, to improve the delivery index (stability to segregation), to reduce the amount of water used and to reduce the filling of the tube
