Special Issue Information

Dear Colleagues,

A large proportion of global carbon emissions comes from the building and infrastructure industry. The goal of ‘green building’ and the ‘green economy’ is to aggressively mitigate the energy demand in civil engineering. This raises new challenges for material scientists, structural engineers, planners, constructors, and operators, for example:

  1. Based on the aim of energy conservation and emission reduction requirements in the process of material extraction and manufacture, how can the ‘green gene’ be implemented in structural materials (such as green cement and concrete)?
  2. Based on the aim of sustainable development during urban regeneration, how can new buildings and infrastructures be built (and existing structures be upgraded) in a manner that ensures low carbon emissions?
  3. Based on the aim of achieving sustainability, how should the life cycle assessment be upgraded and updated in the process of scheme planning and structural and construction design, operation, and management?

In the construction and building industry, the pursuit of these new goals requires multidisciplinary collaboration and integration to realize technical innovation whilst targeting carbon neutrality. Meanwhile, based on the pursuit of ‘efficiency’ and ‘sustainability’, the concepts of ‘whole life cycle’, ‘whole process cost management’, and ‘sustainable management’ have been firmly placed at the forefront. How to effectively implement these concepts, however, still requires further exploration.

This Special Issue will generally focus on studies involving structural materials, urban planning, structural design and optimization, and construction and energy management, which are expected to contribute to the proposal of low carbon development in urban regeneration. Therefore, contributions are expected on, but not limited to, the following areas:

  • Building design and planning schemes;
  • Design and analysis of sustainable building materials and structures;
  • Upgrading of existing structures;
  • Examples or case studies of green building and infrastructure;
  • Urban and building energy management;
  • Engineering project management and project cost management;
  • Development of design philosophies and performance criteria of green structures or communities.

Cement-based materials, especially those with low water-cement ratios, often experience premature cracking due to plastic shrinkage in the early curing stages. In this study, the development mechanism of early-age plastic shrinkage of cement paste, and the crack shrinkage control effect of recycled cement paste powder on cement paste, was quantitatively investigated using non-contacting two-dimensional digital image technology. The influence of different replacement rates (5%, 10%, 20% and 30%) of recycled cement paste powder on the major principal strain and crack patterns of cement paste was investigated. Furthermore, the mechanism of recycled cement paste powder on the early-age plastic shrinkage of cement-based materials was explored. The results show that the addition of recycled cement paste powder could suppress the early-age plastic shrinkage of cement paste. An appropriate replacement ratio (10%) of recycled cement paste powder shows a 33.3% time delay in crack appearance and a 28.0% reduction in the major principal strain. However, the higher replacement ratio of 30% shows an adverse effect on the major principal strain, with an increase of 35.1%. The core mechanism of the appropriate recycled cement paste powder on plastic shrinkage reduction lies in its porous nature, which allows for water absorption and release and regulates the moisture state inside the pores. This quantitative research of the major principal strain development of the early-age plastic shrinkage of cement paste can facilitate a better understanding of plastic shrinkage reduction in recycled cement paste powder on cement paste.
