中文摘要：

基于6个普通混凝土实心砖标准试件的对比试验,研究了普通混凝土实心砖在不同等级的约束条件、竖向压力和砌筑砂浆下对回弹值的影响。将24个标准试件试验得到的抗压强度值和回弹值回归拟合,得出了回弹法推定普通混凝土实心砖抗压强度统一公式,并进行了验证试验。结果表明,该公式具有较高精度,可为行业标准《非烧结砖砌体现场检测技术规程》制定提供参考。

英文摘要：

Through 6 comparison tests of soild concrete block masonry specimens by rebound method, the relationship of rebound value of the blocks under different conditions of constraints, vertical load and masonry mortar is analyzed. Based on the comparison and analysis of the experimental data of 24 Soild concrete block masonry specimens, a general calculation formula of compressive strength for soild concrete brick in existing masonry is put forward. By testing compressive strength of the test walls in Sichuan academy of building research, Jiangsu academy of ruilding research and Nanchong quality supervision department, the confirmatory experimental results show the high accuracy of this formula, which can provide some essential bases for revision of industry standard ＂The method of evaluating the non agglomeration brick strength grading by rebound method＂.
