概要

As part of the conservation and restoration work of the Center for the Global Study of Cultural Heritage and Culture (CHC), this study explores the strengthening countermeasures and the quality estimation of rock at Mastaba Idout in Saqqara, Egypt.

The Mastaba Idout was built around 2360BC. The bedrock of this unique underground burial chamber is known to be weak and, as such, an investigation of its condition and quality and an examination of various strengthening methods are reported herein. The results of quality testing for four kinds of strengthening agents for stone in Japan are also examined. The results of quality testing and repairs for the bedrock in Egypt and the results of the quality testing of strengthening agents for dirt in Japan are reported. Quality testing measures the frequency of the accelerating wave generated by striking a rock surface with an impact hammer. The repair methods involve strengthening by coating with a strengthening agent for stone and injecting non-shrink cement slurry into cracks.

This research identified that the site's bedrock was of very low quality and that the strengthening methods were effective. Quality testing of the strengthening agents for dirt found that agent OH100 had good water permeability, good moisture permeability, and minimal negative effects on the compressive strength of rocks.
