The ingress of carbon dioxide and aggressive ions into concrete is usually considered as a
non negligible factor that determines its performance and service life. Unfortunately, the …

More and more researchers are focusing on the service condition of operational tunnel
structures. In sulfate strata, tunnel lining structures are frequently affected by sulfate erosion …

Waste foundry sand (WFS) is a by-product of the metal casting process, which constitutes a
sustainable solution as a replacement for natural sand (NS) in the production of concrete …

Drying–wetting cycles (DWC) are suspected of influencing the performance of concrete
under sulfate attack, but the nature and extent of this influence are still unclear. Therefore …

When coupled with drying–wetting cycles, the deterioration process of concrete subjected to
external sulfate attack (ESA) is significantly accelerated. The impact of moisture variations …

The fracture properties of concrete subjected to drying-wetting cycles in different types of
sulfate solutions were investigated. Five exposure conditions, ie 5% and 10% sodium sulfate …

The objective of this paper is to investigate the properties of polyurethane mortar subjected
to freeze–thaw cycles in sulfate environment. Na 2 SO 4 solutions with 5% and 10% sulfate …

Seawater and sea sand are widely used in marine concrete to overcome the shortage of
freshwater and river sand. However, the effect of the various salts in seawater and sea sand …

Cement-sodium silicate (CS) grout is extensively employed as a grouting material in shield
tunnel synchronous grouting projects. However, in water-rich areas, its hardened grout …

The durability of backfill body is very important to maintain the stability of goaf. To explore
the long-term strength and deformation characteristics of backfill body under the coupling …
