Title:
METHOD FOR CONTROLLING VARIATION IN SLUMP FLOW OF HIGH-FLUIDITY CONCRETE
Document Type and Number:
Japanese Patent JP2006240989
Kind Code:
A
Abstract:
To provide high-fluidity concrete, the fluidity of which is stabilized so that the fluidity of the concrete does not vary much even if the quantity of water in the concrete fluctuates due to some causes.
The high-fluidity concrete exhibiting a slump flow of 50 cm or more is produced by adding a polysaccharide represented by the chemical formula [1] in a compounding ratio of 0.1 wt% or less based on the unit quantity of water and kneading the resulting mixture. (In the formula, R represents hydrogen or an alkali metal).
