Mechanical Properties of Self-Compacting Rubberized Concrete with Different Rubber Types under Triaxial Compression

Different rubber aggregates lead to changes in the effect of stress conditions on mechanical behavior concrete, and studies triaxial properties self-compacting concrete (SCRC) are rare. In this study, 35 cylindrical specimens taking lateral type as variables were prepared study fresh behaviors SCRC under compression, where contains two types, i.e., 380 μm powder 1–4 mm particles, four contents, 10%, 20% 30%. The test results demonstrated that exhibited a typical oblique shear failure mode compression had more moderate descending branch compared with (SCC). presence can significantly improve properties, including initial elastic modulus, peak strain, an improvement range 3%–73% for stress. While mainly targeted deformation abilities toughness improvement, strain ranges 0.1–3.1 times 0.1–1.0 containing respectively, relative SCC. At high at least 12 MPa, loss strength due addition be controlled within which case content particles was recommended most 30%, respectively. Based Mohr-Coulomb theory, criteria different types established. For analysis design purposes, empirical model proposed predict stress-strain considering influence obtained provide valuable reference application rubberized practical projects, especially those involving three-way states requiring high-quality energy dissipation.
