摘要: This article discusses how the electrical resistivity of carbon fiber (CF) reinforced concrete with continuity within cement paste and sand-cement ratio (s/c) 0.75 depends on CF content gravel-sand (g/s). For ≤500 Ω.cm, mortar must exceed 62 vol.% 44 vol.%. The minimum resistivities provided by double percolation (continuity in but no either or mortar), pseudo triple true mortar) are 355, 36, 7.6 respectively. threshold is 0.75% (by mass cement) if g/s ≤1.50 1.5% ≤2.00. = 2.50 1.75% to 3.00. 2.00
