通过对烧结普通砖砂浆回弹法所基于的历史试验进行再分析,认为碳化深度对砂浆回弹值影响不大。在此基础上,通过由不同强度等级的砂浆砌筑而成的烧结普通砖砌体结构进行新一轮砂浆灰缝试验,运用Origin8.0软件对标准砂浆试块强度与砂浆灰缝回弹值进行回归分析,得出了不考虑碳化深度影响的烧结普通砖砂浆回弹曲线。
Through reanalysis of the historical test based on the rebound method of sintering ordinary brick mortar, it is concluded that the depth of carbonation has little effect on mortar rebound value. On this basis, a new round of mortar mortar joint test was carried out by means of mortar masonry masonry masonry masonry construction with different strength grades. Origin8.0 software was used to analyze the strength of mortar mortar test block and mortar ash seam rebound value The regression analysis shows that the rebound curve of sintered ordinary brick mortar without considering the influence of carbonation depth.
