Abstract: PURPOSE: To obtain an chemical admixture composition capable of reducing viscosity of concrete without damaging water reducing properties by blending a formaldehyde co-condensate with specific aromatic compounds with a defoaming agent. CONSTITUTION: This chemical admixture composition for a concrete product comprises a formaldehyde co-condensate with one or more aromatic compounds (A) into which 1-300mols of a 2-3C oxyalkylene group are introduced and one or more carboxyl group-containing aromatic compounds (B) or its neutral salt (X) and a defoaming agent (Y) as necessary components. By introducing the alkylene oxide group to the aromatic formaldehyde co-condensation system, expulsive force of steric hindrance of the alkylene oxide is added to electric expulsive force of essential aromatic system to extremely raise dispersing effect. The use of the defoaming agent with the co-condensate further improves reduction in viscosity and foam entraining properties.
