| description | •Laboratory-scale experiments were conducted by using centrifugation equipment.•Toughness of spun cast concrete was improved by fiber addition.•Strength was not affected by adding fibers with low fractions.•Sulfate expansion was decreased by fiber addition.
The effect of fiber addition on the properties of fresh and hardened concretes casted by centrifugation was investigated. Workability of fresh concrete mixtures, sludge bleeding after centrifuging, and mechanical properties of hardened concrete including compressive and splitting tensile strengths and modulus of elasticity were examined. Post-crack behavior of spun cast concrete was investigated by splitting tensile testing. Considering sanitary sewer environments, concrete resistances against sulfuric acid erosion and sulfate expansion were evaluated. Although the addition of low fiber fractions (below 0.15vol.%) did not significantly affect workability and strength of the spun cast concretes, it enhanced their toughness and resistance against sulfate expansion. |
