EFFECT OF CELLULOSE FIBER ON PROPERTIES OF SELF-COMPACTING CONCRETE WITH HIGH-VOLUME MINERAL ADMIXTURES
In this paper, effects of cellulose fiber in different dosages on fresh and mechanical properties of self-compacting concrete with high-volume mineral admixtures (HMSCC) were investigated. 35％ Class F fly ash and 5％ silica fume in substitution for cement by weight was added in concrete mixtures. Slump, slump flow and flow time of inverted slump cone were conducted to assess the fresh properties of HMSCC. Compressive strength, impact resistance and abrasion resistance of the concrete were determined for the hardened properties in accordance with ASTM standards. The results indicate that cellulose fiber improves fresh properties of HMSCC in appropriate dosage, and improves impact resistance of HMSCC gradually with the increase of cellulose fiber dosage, but plays little contribution to compressive strength. It also improves abrasion resistance of HMSCC through improving its surface mechanical properties.
