REDUCING AGENT FOR BLEEDING AND METHOD FOR PRODUCING CENTRIFUGALLY MOLDED PRODUCT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a reducing agent for bleeding capable of exhibiting stable reducing power for the bleeding, and to provide a method for producing a centrifugally molded product using the reducing agent for bleeding. SOLUTION: (1) This reducing agent for bleeding consists essentially of a sodium type bentonite in <=5.0 SiO2/Al2O3 weight ratio of chemical components. (2) The method for producing the centrifugally molded product comprises adding the reducing agent for bleeding consisting essentially of the sodium type bentonite in <=5.0 SiO2/Al2O3 weight ratio of the chemical components in an amount of 1-12 kg/m3 to a mortar or a concrete.
