METHOD FOR PRODUCING CENTRIFUGALLY FORMED CONCRETE PRODUCT

PROBLEM TO BE SOLVED: To provide a method by which a product can be produced with good workability even in the case that centrifugal force is reduced. SOLUTION: The centrifugally formed concrete product is obtained by tightly solidifying concrete containing a phosphoric ester-based polymer (A) obtai...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method by which a product can be produced with good workability even in the case that centrifugal force is reduced. SOLUTION: The centrifugally formed concrete product is obtained by tightly solidifying concrete containing a phosphoric ester-based polymer (A) obtained by copolymerizing a specified monomer 1 having a polyoxy alkylene group, a phosphoric monoester-based monomer 2 and a phosphoric diester-based monomer 3, hydraulic powder and water under ≥0.5 G centrifugal force.
