“…Soil is mixed with water at a water content, ws, higher than liquid limit to obtain a slurry; cement, whose amount can be defined through the cement factor c/s, that is the ratio between the anhydrous cement (c) and the dry soil (s) [1], is added to soil slurry at a specific value of wc/c, that is the ratio between water and cement by weight. The amount of foam can be set based on different approaches [8,17,19]. In this study, the porosity induced by foam nf, defined as the ratio of volume of foam to theoretical total volume of material, was adopted.…”

One of the main problems encountered in civil engineering is the management of large amounts of excavated soil, especially when the mechanical properties of this soil are not suitable for its reuse as a construction material. However, the excavated soil could represent a resource if appropriately improved. A suitable solution is the addition of cement and foam to produce lightweight cemented soils (LWCS). In this paper, an insight into the influence of foam on chemo-mineralogical and microstructural features of soil-cement-water system is presented. Time dependent mineralogical and microstructural changes have been monitored by means of X-Ray Diffraction, Thermo-gravimetric analysis and Mercury Intrusion Porosimetry. The present study shows that addition of foam does not alter the chemo-physical evolution of the soil-cement-water system. Large voids are present in the samples as footprint of air bubbles upon mixing, thus increasing porosity. Macroscopic behaviour of treated samples has been investigated by direct shear and oedometric tests. Chemo-physical evolution induced by cement addition is the major responsible for mechanical improvement showed by treated samples. Porosity of samples induced by foam addition plays a key role in the mechanical response of LWCS, inducing a transition of stress-strain behaviour from brittle and dilative to ductile and contractive as a function of increasing foam content.

“…Due to low bulk density, this material can prove to be useful for construction purposes on soft soils, as shown by some authors [12][13][14]. However, chemo-mechanical properties of lightweight cemented soils have not been extensively investigated [15][16][17].…”

“…As lightweight concrete is now increasingly used in medium and high-rise buildings worldwide including Thailand, the development of sustainable lightweight construction material using WTS as an aggregate is the focus of this paper. Natural soil has been successfully used as an aggregate to develop a lightweight cellular material using Portland cement as a cementing agent [37][38][39][40][41]. The development of lightweight cellular material using WTS as an aggregate and geopolymer as a cementing agent has however not been previously investigated.…”

This study examines the effect of polypropylene fiber on the flexural strength properties of lightweight foam mixed soil (LFS). The flexural properties of LFS comprising different proportions of polypropylene fiber (58 mm) at different volume fractions (0.5%, 0.75%, and 1%), three different cement contents of 100, 150, and 200 kg/m3, and densities of 0.8, 1.0, and 1.2 g/cm3 were thoroughly investigated. The flexural performance of LFS according to ASTM C1609 was achieved after 28 days of aging. The results show that the flexural characteristics of LFS could be enhanced by fiber additives, as indicated by the increase in the flexural/residual strength and equivalent flexural strength ratio. The flexural performance is also related to the mixing components, including the density and cement content. For the toughness behavior, the equivalent flexural strength ratio reached up to 100%, which could be achieved with the strain-hardening specimens. The fiber inclusion is more efficient with an increase in the density and cement content of specimens as shown by the overall rating of the flexural performance.
