Autor: Kouji Yasuda, Kenta Masuda, Takayuki Homma, Toshiyuki Nohira, Koki Ichitsubo, Rika Hagiwara, Tetsuya Toba
Publikováno v: ECS Transactions. 50:119-126
Direct electrolytic reduction of powdery SiO2 has been investigated in molten CaCl2 at 1123 K aiming at a low cost and mass production of solar-grade Si. SiO2 powder was set on a Si plate which was installed at the bottom of the crucible and connecte

The effect of cooling rate on the fluidity of mortar made from kiln clinker
Autor: Koki Ichitsubo, Makihiko Ichikawa, Daisuke Kurokawa, Takashi Nakano
Publikováno v: Cement and Concrete Research. 38:643-648
The effect of cooling rate on the fluidity of mortar is investigated. This study proposed a model for the early hydration of C 3 A In this model, the amount of C 3 A hydrated initially is almost proportional to the size of C 3 A and the C 3 A content
