Marine work Portland cement
The invention belongs to the technical field of Portland cement, and particularly relates to maritime work Portland cement. The invention relates to maritime work Portland cement, which is prepared from the following components in percentage by mass: 33.45 to 37.63 percent of clinker, 4.61 to 5.19 percent of limestone, 1.94 to 2.19 percent of desulfurized gypsum and the balance of superfine mineral powder, totaling 100 percent. According to the marine Portland cement and the preparation method thereof, various quality indexes of the prepared marine Portland cement meet and are superior to GB/T 31289-2014 requirements through screening of a marine Portland cement formula, the 3d compressive strength is not lower than 15.0 MPa, the 28d compressive strength is not lower than 42.5 MPa, and the early strength is improved to 15.0 MPa or above; in addition, the corrosion resistance coefficient and the sulfuric acid corrosion resistance condition can meet the standard requirements of GB/T 31289-2.14. The method is of great significance to development and improvement of consumption of industrial waste residues and development of maritime work Portland cement with high corrosion resistance.
本发明属于硅酸盐水泥技术领域，具体涉及一种海工硅酸盐水泥。一种海工硅酸盐水泥，以质量百分比计，所述海工硅酸盐水泥由以下成分制备而成：熟料33.45‑37.63％、石灰石4.61‑5.19％、脱硫石膏1.94‑2.19％，超细矿粉补充至100％。本发明通过海工硅酸盐水泥配方的筛选，制备得到的海工硅酸盐水泥各项品质指标符合并优于GB/T 31289‑2014要求，3d抗压强度不低于15.0MPa，28d抗压强度不低于42.5MPa，且早期强度提高至15.0MPa及以上；另外，抗蚀系数和抗硫酸侵蚀情况方面均能满足GB/T 31289‑2.14的标准要求。这对开发提高工业废渣的消耗量及开发高抗蚀性的海工硅酸盐水泥具有十分重要的意义。
