国内外小芯样法研究综述

Research Overview of Small Core Sample Methods at Home and Abroad

小芯样法是与大芯样法(常规芯样法)相对应的一种微损检测方法,最早出现在天津,发展一直不是太好,25年的历史进程中,只有80篇中外文献,研究方向绝大部分集中在强度研究,其他混凝土质量方面(裂缝宽度、碳化深度和完整性)涉及不多,检测理论与实践不足,导致目前检测规范或规程尚未收录小芯样法的研究成果,建立统一的检测标准尚需进一步研究。

The small core sample method is a kind of micro-damage detection method corresponding to the large core sample method（conventional core sample method）. It first appeared in Tianjin, and its development has not been very good. In the 25 years of history, there are only 80 Chinese and foreign literature, and most of the research direction focuses on the study of strength, the study on the concrete quality（the width of the crack, depth and integrity of carbonation） is not enough, and the detection theory and practice is not enough, so in the current test norms or procedures have not yet included the study results of small core sample method, and the establishment of a unified testing standards still need further study.
