| 中文摘要: |
| 利用试验室成型的C60混凝土试块（原材料不经任何处理），以及实体建筑中取回的C45混凝土芯样，对试验总结出的硬化混凝土（粗骨料经过水洗、细骨料为ISO标准砂、胶凝材料为基准水泥）中砂浆含量测定方法进行验证，结果得知： “整样高温处理法”测定实体混凝土建筑中砂浆含量的误差不超过3%，且为正误差，能够很好地应用于硬化混凝土中胶凝材料含量的测定。 |
| 英文摘要: |
| Using the C60 concrete test block (raw material without any treatment) formed in the laboratory, and the C45 concrete core sample retrieved from the building, the hardened concrete (the coarse aggregate is washed with water, and the fine aggregate is ISO standard) Sand and the benchmark cement are used as cementitious materials) to verify the mortar content determination method, and the result is that: The "whole sample high temperature treatment method" has an error of no more than 3% in the determination of mortar content in concrete buildings, and it’s a positive error, which can be well applied to the determination of cementitious material content in hardened concrete. |
