一、木素磺酸钙减水剂对混凝土或砂浆的特效木素磺酸钙减水剂是一种表面活性剂,加入混凝土或砂浆中能对水泥颗粒起扩散作用,从而把水泥凝胶体中所包含的水释放出来,使水泥达到充分水化。例如,水泥中加入0.2～0.3％(对水泥用量)的木素磺酸钙以后增加可塑性,这是由于液相的木素磺酸盐的阴离子,被固相水泥颗粒表面的阴离子所吸附,使水泥颗 1. Calcium lignosulphonate water reducer effect on concrete or mortar Lignosulphonate water reducer is a kind of surface active agent. It can be added to concrete or mortar to spread cement particles, so that cement gel can be used. The water contained in it is released so that the cement can be fully hydrated. For example, the addition of 0.2-0.3% (for cement) of calcium lignosulfonate increases the plasticity in cement because the anion of the lignosulfonate in the liquid phase is adsorbed by the anions on the surface of the solid-phase cement particles. Cement particles
