Title:
SELF-FILLING CONCRETE COMPOSITION
Document Type and Number:
Japanese Patent JP3285457
Kind Code:
B2
Abstract:
PURPOSE: To obtain a self-filling composition having high fluidity, excellent filling performance and separation resistance by adding a high performance water reducing agent and a specific alkylamine oxide as essential components in a concrete composition.
CONSTITUTION: This self-filling concrete composition contains an alkylamine oxide having a 8-22C alkyl and a high performance water reducing agent and has ≥50 slump flow value (a spreading measured by JIS-A1101). The concrete composition has no inhibiting phenomena in fluidity, which usual compositions ever have, has a large material-separation resistance and excellent in self-filling performance, so it is not necessary to reduce compaction or carry out compaction in case of applicating the concrete composition and the environment against large noises can be improved. When the carbon number of the alkyl groups is <8, the viscosity shows a tendency to decrease and when it is >22, the solubility in water shows a tendency to decrease.
