Abstract

En 中文

• Shrinkage and creep of concrete with four tunnel muck aggregate lithologies were investigated. • Sandstone concrete showed the highest shrinkage, while granite concrete showed the highest creep. • Lithology affected long-term deformation through skeletal restraint and ITZ stability. • ACI 209.2R-08 and CEB-FIP 2010 models were recalibrated using lithology-dependent factors. • A risk zoning framework was proposed for sustainable use in mountain transportation infrastructure.
