Cement modifier
The invention provides a cement modifier which is characterized by being prepared from the following components in percentage by weight: 10 percent to 20 percent of redispersible latex powder, 1 percent to 5 percent of hydroxypropyl methyl cellulose HPMC, 40 percent to 60 percent of silica fume and 30 percent to 50 percent of metakaolin. By adding the cement modifier, the strength, the bonding capacity, the impermeability and the like of ordinary cement can be greatly improved.
一种水泥改性剂，其特征在于该水泥改性剂以重量百分含量计，由以下组分组成：可再分散乳胶粉：10％‑20％，羟丙基甲基纤维素HPMC：1％‑5％，微硅灰：40％‑60％，偏高岭土：30％‑50％。通过掺加该水泥改性剂可大大提高普通水泥的强度，粘结能力以及抗渗性能等。
