Abstract

White sandstone in underground structures may be exposed to chemical attack and temperature variation at the same time, but the resulting change in its creep-stage transition has not been clearly quantified. In this work, specimens collected from Zigong, Sichuan Province, were conditioned in H₂SO₄ solution (pH = 1), distilled water, or NaOH solution (pH = 13) at 0 °C, 25 °C, 50 °C, 75 °C, and 100 °C, and were then tested under uniaxial stepwise loading. The complete strain-time records retained the usual sequence of primary, secondary, and tertiary creep in every group. The main difference was the stress at which accelerated deformation began. For specimens treated in distilled water, this threshold was 24 MPa at each temperature. For the acid- and alkali-treated specimens, it remained 24 MPa from 0 °C to 50 °C, decreased to 20 MPa at 75 °C, and reached 16 MPa at 100 °C. Thus, temperature alone did not alter the threshold under neutral conditions within the tested range; its influence became pronounced when a reactive solution was present. The results are consistent with heating-enhanced water-rock reactions that advance internal deterioration and bring forward the transition to unstable creep. These observations provide direct experimental evidence for evaluating chemo-thermal effects on the full creep response of white sandstone.
