Abstract:According to six groups of crumb rubbers concrete (CRC) with different steel fibers volume ratios and nano-silica contents (SFNS-CRC) under uniaxial test, discussing the effect of steel fiber and nano-silica content. Through data collection and analysis, a computational model for the Compressive strength and Modulus of elasticity on SFNS-CRC is proposed. Based on Weibull distribution and the hehypothesis of strain equivalence, one damage constitutive model was proposed by introducing one damage threshold parameters. Test results indicate that Relationship between compressive strength and Modulus of elasticity is different from natural concrete, but is similar to CRC. Regression formula of compressive strength, Modulus of elasticity, and the damage model curves are suggested. | |||

Abstract:Both positive and negative piezoresistivity occur in cement-matrix composites containing short carbon fibers due to the variation of moisture content in the composites. For most cases the electrical resistivity of the composites decreases monotonically upon longitudinal compression, and piezoresistivity tends to be positive. However, its magnitude varies. Lower moisture content leads to stronger piezoresistivity. When moisture content is in a specific range, the electrical resistivity of the composites increases monotonically upon compressive strain, and piezoresistivity tends to be negative. This effect is much stronger than positive piezoresistivity. The transition from positive to negative piezoresistivity is observed. It is proposed that the occurrence of these phenomena is attributable to decreases in both pore network connectivity and capillary porosity during compression. | |||
