    名古屋大学博物館では,これまで国内外の研究機関と共同で国内史跡の石材調査,軍艦島などの古いコンクリート分析の他,海外(ヨルダンなど)での古代遺跡の発掘調査を行なってきている.これらのこれまでの調査から,石材や古いコンクリートの劣化は酸性雨などによる炭酸カルシウムの溶出が主たる原因であり,また海外の石材や煉瓦は炭酸カルシウムが豊富に含まれているものが多く,乾燥地域でも長期間におけるこれらの溶出が劣化・崩壊の主な原因であることが分かってきた.本音件研究では,コンクリーション化剤によってこれらの影響を上記研究計画によって固定化させ劣化を抑制する手法を開発する.

    Aggregate in concrete is considered to be an inactive material and is not involved in the hydration reaction of cement. However, detailed physical tests and chemical analyses of 50-year-old concrete structures suggest that feldspars in concrete tend to react with calcium hydroxide. In this study, we selected rock minerals that can be used in concrete, and confirmed whether or not they react with calcium hydroxide, which is a typical hydrate of cement, and the temperature dependence of the reaction. The results showed that the minerals reacted with calcium hydroxide to form calcium aluminosilicate hydrate and a kind of zeolite, which contributes to the strength development in concrete.

    This study is concerning about the spherical calcium carbonate concretion yield from sedimentary rocks and we could reveal the rapid formation process and used this process to develop synthetic concretion resin developed with private chemical company as well as to get a patent. Now we have almost the last stage before to make commercial materials distributed in our society.

    Based on the study, the process of spherical concretions formation was revealed as follows; 1)spherical carbonate concretions are only found in marine sediments. 2)Sphere is formed by the diffusive process. 3)The reason why carbonate has been accumulated, is the process by the reaction with carbon and calcium in the sea water. 4)The fossils inside was well preserved, because of the reason by self sealing. 5)The reaction of carbon and calcium to form concretions is quite rapidly that before we had thought.

    Spherical Fe-oxide concretions in both in Utah and Mongolia have been investigated to understand the geochemical migration features relevant to the heavy metal adsorption. The results are not only Uranium but other REE elements are concentrated in the layer of Fe rich crust. This feature might be used for future heavy metal absorption and fixation technology.
