Municipal sewage sludge incineration ash (MSSIA) is commonly used as a raw material in concrete, but few studies have focused on the long-term environmental tolerance of municipal sewage sludge incineration ash concrete (MSSIAC). In this study, acid rain leaching, salt erosion, and freezing-thawing freezing–thawing tests were used to evaluate the long-term environmental behavior of the optimal MSSIAC formulation. One optimal MSSIAC formulation replaces 5% MSSIA, and results in a 7.2% increase in unconfined compressive strength (UCS), indicating that MSSIA-amended concrete can have enhanced UCS. Only Zn was released from the optimal MSSIAC formulations (replacing 5% or 10% MSSIA) in the acid rain leaching test, but only up to 0.071 mg Zn L⁻¹, which was within the acceptable environmental range. No heavy metals were released at concentrations above the method detection limits in the salt erosion and freezing-thawing freezing–thawing tests. The optimal MSSIAC formulations have excellent long-term environmental tolerance while meeting the requirement of UCS, and provide a valuable use for MSSIA.

市政污水污泥焚烧灰渣（MSSIA）通常用作混凝土的原料，但很少有研究关注市政污水污泥焚烧灰渣混凝土（MSSIAC）的长期环境耐受性。在这项研究中，酸雨淋滤，盐分侵蚀和冻融冻融测试用于评估最佳MSSIAC配方的长期环境行为。一种最佳的MSSIAC配方替代了5％的MSSIA，导致无侧限抗压强度（UCS）增加7.2％，这表明用MSSIA改良的混凝土可以提高UCS。在酸雨淋滤试验中，最佳的MSSIAC配方（代替5％或10％的MSSIA）仅释放了Zn，但最多释放出0.071 mg Zn L ^-1，这在可接受的环境范围内。在盐蚀和冻融冻融测试中，没有超过方法检测极限的浓度释放出重金属。最佳的MSSIAC配方在满足UCS要求的同时具有出色的长期环境耐受性，并为MSSIA提供了有价值的用途。
