Underground engineering cement grouting material and preparation method thereof
The invention discloses an underground engineering cement grouting material and a preparation method thereof. The underground engineering cement grouting material is prepared by combining 20-30 parts by mass of clay, 10-15 parts by mass of gypsum, 3-8 parts by mass of an inorganic ferric salt and 2-7 parts by mass of inorganic aluminum salt on the basis of 100 parts by mass of limestone. The preparation method comprises the following steps: S1, crushing limestone, clay and gypsum in parts by mass for later use; S2, heating the limestone according to the mass parts, wherein the heating time is 2-3 d, the temperature is 550-650 DEG C, and a raw material a is obtained; S3, mixing the raw material a with the clay and the gypsum crushed in the step S1, adding corresponding parts by mass of inorganic ferric salt and inorganic aluminum salt in the mixing process, adding a dispersing agent, stirring for 3-5 hours, and drying after stirring to obtain a raw material b; and S4, calcining the dried raw material b at the calcining temperature of 1300-1500 DEG C for 1-2 days to complete the preparation. According to the cement grouting material and the preparation method thereof, the setting and hardening speed of cement is high, and the strength is improved.
本发明公开了一种地下工程水泥注浆材料及其制备方法，以质量份数为100的石灰石基础上结合黏土20‑30份、石膏10‑15份、无机铁盐3‑8份、无机铝盐2‑7份。S1、按照各组分质量份数将石灰石、黏土、石膏进行破碎，待用；S2、按照质量份数将石灰石进行加热，加热时间为2‑3d，温度为550‑650℃，得到原料a；S3、将原料a与步骤S1中粉碎后的黏土、石膏进行混合，在混合过程中添加相对应质量份数的无机铁盐和无机铝盐，并添加分散剂，进行搅拌，搅拌时间为3‑5h，搅拌完成后进行干燥，得到原料b；S4、将上述干燥后得到的原料b进行煅烧，煅烧温度为1300‑1500℃，煅烧时间为1‑2d，制备完成。本发明的水泥浆液材料及其制备方法使水泥凝结硬化速度快，强度增加。
