Special Issue Information

Dear Colleagues,

The emphasis of this Special Issue, titled “Research and Utilization of Solid Waste and Construction Waste”, is on the reduction and engineering reuse of solid waste and construction waste.

The main topics covered within this thematic Issue are as follows:

  • Advanced waste treatment technologies;
  • Recovery of solid waste to prepare functional materials;
  • Awareness of hazards and risks posed by construction solid waste to human health and the environment.

We welcome researchers in this field to contribute original research, reviews, and communications that push the boundaries of our knowledge about recycling solid waste. This Special Issue provides a platform for addressing challenges and presenting breakthroughs in solid waste treatment.

Bond performance served as a crucial foundation for the collaboration between concrete and steel rebar. This study investigated the bond performance between coal gasification slag (CGS) concrete, an environmentally friendly construction material, and steel rebar. The effects of fine aggregate type, steel rebar diameter, and anchorage length on bond performance were examined through bond-slip tests conducted on 16 groups of reinforced concrete specimens with different parameters. By utilizing experimental data, a formula for the bond strength between steel rebar and CGS concrete was derived. Additionally, the BPE bond-slip constitutive model was modified by introducing a correction factor (k) to account for relative protective layer thickness. Findings indicated that substituting 25% of manufactured sand with coal gasification slag did not cause significant adverse effects on concrete strength or bond stress between concrete and steel rebar. The effect of steel rebar diameter on the ultimate bond stress was not obvious, whereas when the steel rebar diameter was fixed; the increase in anchorage length led to uneven distribution of bond stress and eventually reduced the ultimate bond stress. The modified bond-slip constitutive model agreed well with the experimental values and was able to more accurately reflect the bond-slip performance between CGS concrete and steel rebar. This study provided a theoretical basis for the conversion of CGS into a resource and for the application of CGS concrete. Full article
