Article Synopsis
  • Controlled experiments were conducted to analyze the aerosol characteristics of fragmented MWCNT-enhanced concrete, which provided insights into the size, concentration, and behavior of these particulates when inhaled.
  • Results showed that while MWCNTs reduced air-borne particle emissions in light-weight porous concrete, they increased emissions in normal concrete, indicating complex interactions depending on concrete type and MWCNT concentration.

Rice husk ash (RHA) having a porous sructure and a high amount of amorphous silica nanoparticles (4 nm) decorated on the surface of carbon nanosheets is a suitable and cheap candidate for the use of a grout additive. In this study, neat RHA and functionalized RHA (f-RHA) with three different loadings were successfully incorporated into the cement-bentonite based grouts by adjusting the water to cement ratio. The workability of the developed grouts having RHA-based additives was analyzed in terms of bleeding, density, flow spread, and Marsh cone time.
