Special Issue Information

Dear Colleagues,

Because it can potentially put all human civilization in danger, global warming is a significant problem affecting the whole planet. In addition to other factors, the cement and concrete sector is responsible for a significant amount of the emissions that contribute to climate change. In this review, various perspectives on the uses and potential uses of cement and concrete as a green material were discussed, as well as guidelines for green concrete, green cement production, the utilization of recycled materials in concrete, green cement, and concrete composites, and green concrete as a material for repairing damaged structures. When it comes to the development of cleaner technologies for the production of concrete, the primary goals include achieving a significant reduction in CO2 emissions, (b) achieving a significant reduction in energy consumption and fossil fuel in the cement-manufacturing process, (c) achieving a significant reduction in the use of substances that are hazardous to health and/or the environment, and (d) achieving significant savings associated with the use of cement by partially replacing it with fly ash waste and/or other kinds of waste.

This Special Issue is named "Advanced Cementitious Materials for Sustainable Infrastructure," and it covers a variety of topics that are connected to the manufacturing of environmentally friendly cement and concrete materials as well as their use in building endeavors. Screening is done on various sources of sustainable green cement-based materials, as well as their applications in various construction sectors (buildings, roads, railways, airports, ports, tunnels, and bridges). These materials include, but are not limited to, pozzolanic materials, supplementary cementitious materials and hybrid nano-materials. Literature studies and articles that discuss the state of the art are very valued since the use of such materials in civil construction engineering continues to be a relatively new subject.

I look forward to receiving your contributions.

Peatlands are more likely to be affected by intense precipitation and soil erosion, thus requiring modifications for stabilized soil and subgrade protection. This experimental study aimed to find a suitable pavement type using fly ash, an unutilized byproduct from coal burning processes, for peatland areas with a low bearing capacity. We designed lightweight concrete specimens using 15% fly ash substitution to be incorporated into rigid pavement construction. The concrete quality was assessed through compressive and flexural strength tests performed at the ages of 7, 14, and 28 days in order to shorten the project durations and prevent further traffic delay. The obtained results suggested that the substitution of fly ash in 15% of the lightweight concrete mixture can be taken into account to achieve a mixture of a lightweight concrete that meets the general specification criteria for cement-treated subbases (CTSBs). Furthermore, the utilization of fly ash as a new material is considered substantial in managing existing waste-related environmental problems, as well as soil stabilization and subgrade protection problems for low-bearing-capacity soil areas.

The characterization and analysis of the cementation properties of novel biopolymer binders in soils are essential for their potential application in geotechnical engineering. This study investigates the cementation effect of a novel zein biopolymer binder on sandy soils. Soil specimens are mixed with various contents of zein biopolymer ranging from 0 to 5%. The mechanical and microscopic characteristics of the treated specimens are evaluated using unconfined compression tests and scanning electron microscopy, respectively, after curing for 3, 7, and 28 days. The results show a consistent increase in compressive strength and elastic modulus of treated soils with increasing curing periods and biopolymer contents. A small amount (1%) of zein biopolymer increases soil strength and elasticity regardless of gradation. Additionally, the bonding force between the soil–zein biopolymer increases linearly with soil uniformity. Therefore, the application of zein biopolymer can be potentially used as a binder for fine- and coarse-grained soils in geotechnical engineering considering its stabilization and sustainability properties.
