CONCRETE COMPOSITION, CONCRETE STRUCTURE, AND CONCRETE ADDITIVE

摘要

PROBLEM TO BE SOLVED: To provide concrete with functions such as gas absorption and deodorization without damaging the basic strength property and durability of the concrete structure.

SOLUTION: The concrete composition contains pitch coke particles (A) with average diameter of 0.5-10 mm, carbon ratio of≥90%, and hardness of≥5.1 kg and strengthened carbon particles (B) with an average diameter of 0.5-3 mm which is formed by carbonizing plant materials, where A and B are controlled to be A:B=9:1-7:3 and A+B=1-3 wt.%.
