Abstract

PURPOSE: To shorten the period of curing and to increase the strength of pellets by adding 2CaO.SiO2 to starting materials, pelletizing them by an ordinary method, and curing and hardening the pellets in a gaseous CO2 atmosphere.
CONSTITUTION: To starting materials for unfired pellets is added ≥wt% 2CaO. SiO2, and they are pelletized by an ordinary method. Converter slag or electric furnace slag contg. much 2CaO.SiO2 may be used in place of the 2CaO.SiO2. 2CaO.SiO2 may be manufactured by adding silica sand to commercially available limestone and calcining them in a cement kiln. The pellets are cured and hardened in a gaseous CO2 atmosphere.
