[摘要]回彈法是檢測砌體結構中砌筑砂漿強度的一種常用方法,具有測試快速、操作簡便等特點。結合試驗研究與工程實踐,討論了采用回彈法檢測砌筑砂漿強度時存在的測位回彈點數量偏少、回彈點選擇及回彈數據取舍沒有統(tǒng)一標準等問題,分析了上述問題對砌筑砂漿強度推定結果的影響,并提出了增加測位內回彈點數量等改進建議,以期為回彈法檢測砌筑砂漿強度的工程應用及相關規(guī)程修訂提供參考。

Abstract: Rebound method is a common used method to test masonry mortar compression strength, with rapid measurement, simple operation and other characteristics. Combined with the experimental research and engineering practice, some problems about rebound method in testing masonry mortar strength were discussed, such as the quantity of rebound points in one testing area may be few, and there is no uniform standard for rebound point selection and rebound data choice. The influence of above mentioned questions on the mortar strength presumption was analyzed. Improvement suggestions such as increasing rebound point quantity in one testing area were put forward in order to provide reference for the engineering application and for the further revision of relative standard.
