为建立一种损伤最小的混凝土抗压强度估算方法进行了基础性研究。本研究的重点是硬化水泥的强度发展，以确定是否可以估计水泥浆体的强度从钻粉的性能。从试样中收集的钻粉样品的氦气真密度，粒度分布和孔体积进行了测量，并与试样的抗压强度进行了比较。确定了支配硬化水泥的抗压强度的信息保留在钻孔粉末的孔结构中。
A fundamental study was conducted to develop a method for estimating the compressive strength of concrete with minimal damage. This study focused on the strength development of hardened cement to determine whether the strength of the cement paste could be estimated from the properties of the drilling powder. The helium true density, particle size distribution, and pore volume of drilling powder samples collected from the specimens were measured and compared with the compressive strengths of the specimens. It was determined that the information that governs the compressive strength of the hardened cement remained in the pore structure of the drilling powder.
