MODIFIED AGGREGATE AND CONCRETE HAVING MODIFIED AGGREGATE

摘要

PPROBLEM TO BE SOLVED: To provide a modified aggregate capable of recovering a high quality modified aggregate in the modified aggregate having an equivalent level in respect of cost and/or performance in comparison with an existing natural aggregate without damaging the strength of a concrete structure at the time of usage and to provide the concrete etc. having the modified aggregate. PSOLUTION: The modified aggregate has (1) a dielectric body and (2) a fine powder for strengthening an adhesive force between the aggregate and a cement hardened body and having an average particle size of 0.01-100 m on the surface of the aggregate and the concrete has the modified aggregate.
