SELF-FILLING CONCRETE COMPOSITION

Title:

SELF-FILLING CONCRETE COMPOSITION

Document Type and Number:

Japanese Patent JPH06128001

Kind Code:

A

Abstract:

PURPOSE: To ensure high flowability, high packability, high resistance to aggregate separation, and high strength by specifying the composition of self-filling concrete.

CONSTITUTION: The objective composition contains a high-performance water- reducing admixture and a cationic water-soluble high polymer in an amount of 0.005 to 4.0wt.% based on the cement weight, has a slump value of more than 40cm according to JIS-A1101. The high-performance reducing agent is anionic in aqueous solutions, for example, naphthalenesulfonic acid metal salt formaldehyde condensate, melaminesulfonic acid metal salt formaldehyde condensate, and purified ligninsulfonate salt. The cationic water-soluble high polymer is cationic in aqueous solutions, preferably cationic starch derivatives can be cited. The composition improves the usage of concrete, concrete working, particularly influences noise problems and process rationalization in the production of concrete products.
