In order production manner of the crystal Characteristic tobamoraito high content die concrete and the mixing material null hydraulic property cement for crystal Characteristic tobamoraito high

摘要

PROBLEM TO BE SOLVED: To produce concrete containing crystalline tobermorite in a high content, which contributes to heat resistance, by effectively using fly ash.;SOLUTION: The concrete containing a large amount of crystalline tobermorite is obtained by mixing 48 parts by mass of portland cement, 8.4 parts by mass of slaked lime, 3.6 parts by mass of gypsum, 40 parts by mass of fly ash, 100 parts by mass of quartz sand No. 5 as aggregate, and 43 parts by mass of water, then mixing and kneading the resulting mixture, and subjecting the kneaded material to steam autoclave curing at a curing temperature of ≥180°C.;COPYRIGHT: (C)2006,JPO&NCIPI
