Production method and application of high-strength cement
The invention relates to the technical field of cement, and discloses a production method and application of high-strength cement. The production method comprises the steps of: mixing and grinding prepared calcium oxide, silicon oxide, iron oxide, copper oxide, limestone, volcanic ash, gypsum and glass fibers; screening the ground powder by using a sieve with the size of 0.2-0.3 mm to obtain a cement raw material; preheating the cement raw material, then putting the cement raw material into a rotary kiln, calcining for 0.5-0.6 hour at 1100-1400 DEG C, and introducing air into the rotary kiln during calcining; and adding 3-4 parts by weight of a boric acid ester coupling agent into 80-90 parts by weight of absolute ethyl alcohol, mixing well at 60-70 DEG C, adding 90-130 parts by weight of magnesium borate whiskers into the mixture, stirring and mixing well, and carrying out suction filtration and drying to obtain a reinforcing agent. According to the production method and application of the high-strength cement, the flame retardant property of the cement is improved, the breaking strength and wear resistance of the cement are improved, and the strength of the cement is improved.
本发明涉及水泥技术领域，且公开了一种高强水泥生产方法及应用，包括以下步骤：将准备好的氧化钙、氧化硅、氧化铁、氧化铜、石灰石，火山灰、石膏、玻璃纤维混合磨粉；将磨成的粉，使用0.2‑0.3毫米的筛选取，得到水泥生料；将水泥生料，预热，然后放入回转窑内进行煅烧，煅烧的温度在1100‑1400摄氏度，煅烧0.5‑0.6小时，且煅烧时向回转窑内通入空气；将重量份3‑4份的硼酸酯偶联剂加入80‑90份无水乙醇中，于60‑70摄氏度下混合均匀后，再将90‑130份硼酸镁晶须加入到其中，搅拌混合均匀后抽滤，干燥，得到增强剂。该高强水泥生产方法及应用，提高了水泥的阻燃性能，增加水泥的抗折强度和耐磨性能，提高了水泥的强度。
