NOVELTY - A self-compacting shrinkage compensation concrete comprises 330-360 pts. wt. cement, 80-100 pts. wt. fly ash, 60-80 pts. wt. mineral powder, 950-1050 pts. wt. crushed stone, 600-700 pts. wt. fine sand, 40-60 pts. wt. expanding agent, 4-6 pts. wt. water reducer, 160-180 pts. wt. water, and 20-40 pts. wt. modified basalt fiber. The modified basalt fiber is prepared by performing acid modification by mixing basalt fiber and dilute sulfuric acid solution, heating, soaking, solid-liquid separating, washing, drying to obtain pretreated basalt fiber (A), performing graphene modification by dispersing graphene oxide in water, adding aminosilane coupling agent (A), mixing, adjusting the pH to acidic to obtain modifier, soaking the fiber (A) in the modifier, drying to obtain graphene oxide modified fiber (B), performing grafting modification by dissolving the aminosilane coupling agent (B) in water, adding fiber (B) and nano silicon dioxide, and solid-liquid separating. USE - Self-compacting shrinkage compensation concrete. ADVANTAGE - The self-compacting shrinkage compensation concrete has low shrinkage rate and excellent mechanical properties.
