F and R are early strength types in cement varieties; 2. PKZ is limestone Portland cement; PZ is oil shale Portland cement; 3.3d strength according to R3d=R2d × Calculated by 1.175. From Table 1, it can also be seen that Germany mainly produces and uses early strength cement, with early strength cement accounting for 78.8% in 1981 and 83.6% in 1997. The proportion of high-grade cement is even higher, with 52.5% of early strength cement accounting for 89.5% in 1997. There is still a trend to expand the use of early strength cement in the future. Table 4 shows several cement strength values calculated by China Building Materials Research Institute, and Table 5 shows production data of several cement factories. From the comparison of Tables 3, 4, and 5, it can be seen that the early strength of cement in China is much lower in both absolute and relative values than in Germany. If a new inspection method is used, it will be much lower. The relative value of 3D strength of early strength cement in China is also at least 10-20 percentage points lower than the relative value in Germany. The cement listed in Table 5 is of high quality, which can represent a good level, while the difference in general quality cement is even greater.
