Abstract

According to the experimental results of researchers recently seen, there is a case where a significant difference between data of several reports and measured powder is detected, and concrete examination on this is necessary. In this study, we compare the actual powdered degree of powdered aid on the report against 20 OPCs that are actually being brought into the raw concrete plant, and the OPC powder also influences the difference of OPC powder's strength characteristics on hardened mortar Was analyzed. As a result of the analysis, doubts were raised on the reliability of the OPC powder degree described on the certificate, and the bending and compressive strength tended to increase as the degree of fineness of the measured OPC increased.
