“…The final objective of this study is to discuss effective soft soil improvement techniques. Based on literature and observations through some historical cases, preloading and prefabricated vertical drains [136,138] and geofoam as lightweight fill materials [145,146] are widely used today. The study found that both techniques are environmentally friendly.…”

“…Therefore, the unconfined compressive strength is dependent on the mixed material used. The material mixture used in cellular concrete as foam content + bottom ash [146], flue ash [147] and aluminium powder [148] produces a compressive strength of 0.8-5.2 MPa, 1.7-2.7 MPa and 0.9-7.9 MPa, respectively. The use of geofoam is well received because it is more practical as a readily-available source, and there are many manufacturers and suppliers around the world [149].…”

This paper presents an exhaustive review of the challenges faced in the construction of road embankments on soft ground and proposes a direction for future development. Frequently used techniques for soft ground improvement are discussed. The factors that contribute to the stability of the road embankment are reviewed by approach, results of past studies, and historical cases. The findings show that settlement, slope stability, and soil bearing capacity are all challenges to constructing the road embankment. Additionally, it is found that geometric data is a key factor in embankment design. Pre-loading with prefabricated vertical drain (PVDs) methods and lightweight fill were found to be widely used techniques in soft ground improvement. The information from this study can be used to develop design guidance systems, numerical modelling, and to give an overview and knowledge to other researchers who are or will conduct research in this field. Finally, future perspectives for research are related to predictions of factors that affect the stability of road embankment with an artificial intelligence approach.

is study aims to investigate the relationship between the heat of hydration and the strength development of cast-in-situ foamed concrete. First, indoor model tests are conducted to determine the effects of the casting density and the fly ash content on the hydration heat of foamed concrete in semiadiabatic conditions. Second, compression tests are carried out to evaluate the development of the compressive strength with the curing time under standard curing conditions and temperature matched curing conditions. ird, the hydration heat development of the foamed concrete is tested in four projects. e results showed that the peak temperature, the maximum temperature change rate, and the maximum temperature difference increased with the increase in the casting density at different positions in the foamed concrete. For the same casting density of the foamed concrete, the peak temperature, the maximum temperature change rate, and the maximum temperature difference decreased with the increase in the fly ash content. For the foamed concrete without the admixture, the early strength was significantly higher under temperature matched curing conditions than under standard curing conditions, but the temperature matched curing conditions had a clear inhibitory effect on the strength of the foamed concrete. e strengths during the early stage and the later stage were both improved under temperature matched curing conditions after adding the fly ash, and the greater the fly ash content, the larger the effect. e maximum temperature increments were higher in the indoor model test than in the field tests for the same casting density. Reasonable cooling measures and the addition of fly ash decreased the maximum temperature increments and increased the corresponding casting times.

Motivated by the sustainable production perspective, a laboratory testing program is exercised to ascertain the feasibility of utilizing copper slag in place of the natural fine aggregate in concrete. Totally, fifteen concrete mixtures were prepared to incorporate copper slag in place of the fine aggregate in concrete. e attributes of concrete specimens made with varying proportions of copper slag were compared (ranging from 0% to 100% substitution) at a w/c ratio of 0.44, and the optimum percentage of copper slag was decided. e w/c ratio in the mix containing optimum copper slag percentage was then varied (from 0.42 to 0.36) to examine the influence of the change in the quantity of available water on the strength attributes of concrete. Concrete specimens were assessed for workability, density, compressive strength, flexural strength, and split tensile strength. SEM images and X-ray diffractograms of concrete specimens were also studied. e results obtained indicated a significant increase in workability and a small rise in the bulk density of concrete. e study concludes that substituting 60% sand with copper slag results in better compressive strength compared to control concrete and can be improved further by reducing the w/c ratio in the mix.
