作者研制的小直径钻削试验机是一种微破坏试验机，它对被试材料的破坏可以很小。用于检测波特兰水泥砂浆、混凝土等复合材料的强度。进行了一系列实验，以1）避免在钻头周围排出的水泥粉末的不良影响，2）避免钻凿粗骨料，以及3）知道用于钻凿的最佳压力大小。结果表明，可以通过考虑所获得的数据来改进测试方法。
A small-diameter drilling tester developed by the authors is one of the slight-destructive testers, with which the damage of materials tested can be very small. To apply the tester for checking the strength of compound materials e.g. Portland cement mortars, concretes etc., a series of experiments was carried out 1) to avoid the ill effect of cement powder discharged around a drill, 2) to avoid drilling coarse aggregates, and 3) to know the best magnitude of pressure for drilling. As a result, it is clarified that the testing method may be improved by considering the obtained data.
