Development of Concrete Inspection Robot with Dual Stage Suckers

Autor: Kan Yoneda, Yuta Matsumoto, Isao Kurashige

Publikováno v: Journal of Robotics and Mechatronics. 31:816-826

To automate nondestructive inspections for concrete walls by measuring their air permeability, we developed a wall climbing robot with suckers. It is configured to move by alternately moving the central body and the four leg tip suckers forward. The

Effect of carbonate ions on delayed ettringite formation

Autor: Kohki Murano, Isao Kurashige, Shingo Asamoto, Anura Nanayakkara

Publikováno v: Construction and Building Materials. 147:221-226

The effect of carbonate ions gradually dissolved from limestone powder on delayed ettringite formation (DEF) and the inhibition of DEF by fly ash were examined. To accelerate DEF expansion, 3% SO3 by cement weight was added and the specimens were exp

Ionic Diffusivity and Pore Structure of Hardened Cement Paste Exposed to High Temperature Environment for Long Period

Autor: Isao Kurashige

Publikováno v: XV International Conference on Durability of Building Materials and Components. eBook of Proceedings.

Ion diffusion through cement-based barrier is key to safe radionuclide transfer in intermediate radioactive waste disposal facilities. The purpose of this research is to elicit the behavior of ionic diffusivity and pore structure of hardened cement p

Quality Evaluation of Granulated Blast Furnace Slag Sand Via Acid Immersion and Freeze-Thaw Tests

Autor: Isao Kurashige, Takaya Kawato

Publikováno v: XV International Conference on Durability of Building Materials and Components. eBook of Proceedings.

In recent years, the use of granulated blast furnace slag (GBFS) sand as fine aggregate in concrete has been increasingly discussed from the viewpoint of environmental impact reduction and effective utilization of by-products in Japan. The various ph

Influence of Fly Ash on Strength Development of Concrete and its Temperature Dependence

Autor: Hiromi Yanokura, Naoyuki Sugihashi, Isao Kurashige, Keiichi Takahashi, Yasuhiro Kuroda

Publikováno v: XV International Conference on Durability of Building Materials and Components. eBook of Proceedings.

Experiments on the development of compressive strength and static and dynamic Young’s moduli were performed by the following mix proportions of concrete: the first uses different types of Portland cement without fly ash (FA) with a water-cement rat
