Special Issue Information

Dear Colleagues,

Climate change brought about by greenhouse gas emissions is a significant challenge facing our planet. The cement industry is one of the major producers of greenhouse gases, accounting for about 5–7% of the global greenhouse gas emissions. Moreover, the continuous mining of valuable natural resources by the cement and concrete industry to meet the ever-increasing global demand for infrastructure development makes it a long-term sustainability challenge. Therefore, the research and development on cutting down its carbon footprint and transforming it into a carbon-neutral and sustainable material have been subject to extensive and sustained focus. The conservation of natural resources and the recycling of waste materials have become active components of this transformation process that simultaneously supports the global interest in the closed-loop circular economy. Various advancements have been made in developing eco-friendly cement concrete that is becoming more sustainable and proactively supporting the circular economy. Also, pavement technology and soil stabilization processes have been moving towards adopting sustainable approaches and materials.

This Special Issue focuses on novel and fundamental research that paves a way towards developing carbon-neutral and sustainable cement concrete that also encourages the recycling of various waste streams.

The potential topics of interest for this special issue include, but are not limited to:

  • Carbon dioxide curing and mineralization in cement concrete
  • Carbon sequestration from various waste streams in cement concrete
  • Development of zero cement composites
  • Development of low carbon footprint cement composites and pavements
  • Recycling of various waste materials for the replacement of cement and/or aggregates
  • Physicochemical and microstructure studies of the blended cement/concrete composites
  • Impact on indoor air quality, fire resistance, thermal insulation, and acoustic properties.
  • Long-term mechanical and durability studies
  • Development of low carbon footprint pavements
  • Soil stabilization using sustainable materials

Growing concerns on global industrial greenhouse gas emissions have boosted research for developing alternative, less CO2 intensive binders for partial to complete replacement of ordinary Portland cement (OPC) clinker. Unlike slag and pozzolanic siliceous low-Ca class F fly ashes, the Ca- and S-rich class C ashes, particularly these formed in circulating fluidised bed combustion (CFBC) boilers, are typically not considered as viable cementitious materials for blending with or substituting the OPC. We studied the physical, chemical-mineralogical characteristics of the mechanically activated Ca-rich CFBC fly ash pastes and mortars with high volume OPC substitution rates to find potential alternatives for OPC in building materials and composites. Our findings indicate that compressive strength of pastes and mortars made with partial to complete replacement of the mechanically activated CFBC ash to OPC is comparable to OPC concrete, showing compared to OPC pastes reduction in compressive strength only by <10% at 50% and <20% at 75% replacement rates. Our results show that mechanically activated Ca-rich CFBC fly ash can be successfully used as an alternative CSA-cement type binder. Full article

Gypseous soil is one type of expansive soil that contains a sufficient amount of sulphate. Cement and lime are the most common methods of stabilizing expansive soil, but the problem is that lime-treated gypseous soil normally fails in terms of durability due to the formation of ettringite, a highly deleterious compound. Moisture ingress causes a significant swelling of ettringite crystals, thereby causing considerable damage to structures and pavements. This study investigated the suitability of various materials (nano–Mg oxide (M), metakaolin (MK), and ground granulated blast-furnace slag (GGBS)) for the stabilization of gypseous soil. The results showed soil samples treated with 20% M-MK, M-GGBS, and M-GGBS-MK to exhibit lower swelling rates (<0.01% change in volume) compared to those treated with 10% and 20% of lime after 90 days of curing. However, soil samples stabilized with 10% and 20% binder of [(M-MK), (M-GGBS), and (M-GGBS-MK)] exhibited higher strengths after 90 days of soaking (ranging from 0.96–12.8 MPa) compared to those stabilized with 10% and 20% lime. From the morphology studies, the SEM and EDX analysis evidenced no formation of ettringite in the samples stabilized with M-MK-, M-GGBS-, and M-GGBS-MK. These results demonstrate the suitability of M-MK, M-GGBS, and M-GGBS-MK as effective agents for the stabilization of gypseous soil. Full article
