1. The determination of the flexural strength results of cement mortar is based on the average value of three measurements from prismatic specimens.2. If one of the three measurements exceeds the average value by more than ±10%, that data point should be discarded, and the average of the remaining measurements should be taken as the final result.3. When two out of the three measurements are greater than the average value by more than ±10%, the remaining measurement should be used as the flexural strength result.4. The measurement of flexural strength of cement mortar is a crucial assessment of cement quality, typically conducted in research, production, and quality control of cement concrete.5. Flexural strength reflects the integrity of the material's internal structure and the magnitude of bond strength.6. When conducting flexural strength tests of cement mortar, it is necessary to strictly follow the standard method for preparing test specimens, including the mix proportion of the mortar, stirring techniques, molding, and curing steps.7. These preparation processes significantly impact the test results and must be meticulously controlled to ensure the accuracy and reliability of the measurements.8. For instance, if the flexural strength measurements of three prismatic specimens are 5.0MPa, 5.5MPa, and 4.6MPa respectively, the calculated average is 5.03MPa.9. Each measurement is within ±10% of the average, thus no data needs to be discarded, and the final result is 5.03MPa.10. The determination of flexural strength results of cement mortar is a precise and systematic process that relies on standardized testing methods and strict data analysis.
