“…The initial concept of amalgamating freshwater and wood chippings was formulated by Geoffrey Pyke in 1942 (Wikipedia 2022). Today, the eponymously named Pykrete continues to be employed for constructing structures in areas with cold climates (Hani and Evirgen 2022). Our research suggests that utilising seawater instead of freshwater for the formation of composite icebergs is a viable proposition.…”

Numerous policies have been proposed to mitigate the problem of climate change as reducing emissions alone will not be sufficient. Carbon Capture and Storage (CCS), which captures carbon at the source, and Negative Emissions Technologies (NETs), which remove carbon from the atmosphere, are two of the most important strategies currently used to combat global warming. Existing technologies, however, are widely believed to be too expensive to implement on a global scale. The estimated total cost of climate change varies greatly, for example, 178 trillion dollars over the next 50 years. Economists have frequently emphasised the importance of minimising expenditure while meeting climate goals. According to new research, NETs may be more cost-effective and less disruptive than various forms of CCS. We anticipate that NETs based on plant growth and biomass freezing in seawater will be the most cost-effective option for capturing and storing 10 gigatonnes of carbon per year, with an operating cost in the order of $50/t CO2. To reverse global warming, policies at the national, transnational, and international levels will need to be overhauled.

“…The three types of soil, sand, gravel 3/8, and gravel 8/16 were defined through the sieving meshes of the grain size distribution analysis test ASTM C136 (2006), as shown in Figure 1. The sampling process for obtaining soil samples is a critical factor in determining the inherent characteristics of soil (Hani and Evirgen, 2023a;Hani and Evirgen, 2023b).…”

One of the most significant mechanisms of deterioration in self-compacting concrete (SCC) structures over the course of their service life is exposure to elevated temperatures. For this reason, the effects of elevated temperatures on the residual mechanical properties of SCC made of various cementitious additions (silica fume (SF), limestone filler (LF), and crushed dune sand (SD)) was investigated via partially substituting amount of Portland cement in the SCC. The SCC was formed and heated with the coupling procedure of heating-cooling at ambient temperatures ranging from 20, 150, 400, 600, and 800 °C. The compressive strength (CS) and ultrasonic pulse velocity (UPV) were measured after cooling at room temperature of 20 °C. The findings show that CS and UPV exhibit intriguing outcomes for all self-compacting concretes. Otherwise, the UPV decreases with temperature in the range of 250 and 800 °C. In addition, at 600 °C, SCC-SF and SCC-SD have the highest residual compressive strengths, 31.20 and 23.80 MPa, respectively.
