“…Avec l'augmentation de la demande de matériaux granulaires dans divers domaines parmi lesquels les travaux publics (Jones et al, 2001 ;Hamer et Karius, 2002 ;Scordia et al, 2008 ;Zentar et al, 2008 ;Tran, 2009 ;Wang et al, 2012), l'utilisation des sédiments marins comme une nouvelle ressource peut dénouer d'une part le problème de gestion des sédiments de dragage et d'autre part l'approvisionnement de secteur avare de matériaux granulaires. Après le prétraitement des sédiments pour enlever de l'eau et éliminer et/ou stabiliser des polluants (matières organiques, métaux lourds), les grands volumes de sédiments marins représentent une source de matières premières très intéressante, notamment pour un secteur consomma teur de granulats tels que la route.…”

“…La moitié de cette quantité est utilisée dans les travaux routiers (UNPG, 2009). Pour l'utilisation des sédiments de dragage en tech nique routière, beaucoup d'auteurs ont entrepris une série d'études sur les sédiments traités aux liants à l'aide d'essais de laboratoire et d'essai in situ (Scordia et al, 2008 ;Silitonga et al, 2008 ;Zentar et al, 2008 ;Zhu et Liu, 2008 ;Sannier et al, 2009 ;Wang et al, 2012). Dans la plupart de ces études, les essais méca niques au laboratoire ou in situ sont réalisés pour des échéances inférieures à 90 jours et très peu de résultats sont disponibles pour des échéances au-delà et sur tout à 360 jours.…”

Estimation of long-term mechanical properties of Dunkerque sediments treated with lime or cement AbstractThe present work in this paper aims to make up the lack of information concerning the evolution of long-term mechanical properties of sediments treated with lime and/or cement. The unconfined compression tests and indirect tensile tests are performed to determine the compressive strength and tensile strength of sediments at different curing times and in particular at 360 days. The tensile strength and elastic modulus measured at 360 days allows evaluating the potential use of designed materials in base course layer. The strength ratios Rtd/Rt360d and modulus ratios Etd/Et360d are experimentally calculated and then compared to those recommended by French standard NF P 98-113 (1994) and NF P 98 114-3 (2001) for standard materials. With the exception of SD6L, the obtained values are slightly below the proposed values for estimating the tensile strengths of materials at 360 days but always above the proposed values for estimating elastic modules at 360 days.

“…The potential of sediments solidified with cement or lime for road construction is evaluated through a proposed methodology from the I CBR value. In their reported research work, Wang et al (2012) characterised Dunkirk sediment as sandy soil. They affirmed that from the point of view of mechanics and applicability in road construction, 6% cement is an economic and reasonable amount to improve the mechanical performance of sediments.…”

“…Through the literature, many researchers (Boutouil, 1998;Boutouil and Saussaye, 2011;Colin, 2003;Duan, 2008;Kamali et al, 2008;Liang, 2012;Maher et al, 2006;Saussaye, 2013;Scordia et al, 2008;Silitonga, 2010;Zentar et al, 2008) studied the possibility of sediment reuse in road construction. Based on the mineralogical composition and physical characteristics of Dunkirk sediments, Wang et al (2012) assessed the effects of cement and lime through modified Proctor compaction and U CS tests. The potential of sediments solidified with cement or lime for road construction is evaluated through a proposed methodology from the I CBR value.…”

This study focused on the feasibility of Tunisian sediment reuse as new road material. Experiments were conducted to investigate sediment reuse as road material. Three mixtures (raw sediments, stabilised sediments with 3% lime and stabilised sediments with 3% cement) were studied with regard to their mechanical performances. The first part of this paper introduces the characterisation of Zarzis sediments. The second part describes the laboratory experiments and the followed methods. The third part is dedicated to the analysis of results. The originality of this work is the use of a minimum percentage of lime, which was determined experimentally. Based on environmental tests, Zarzis sediments were uncontaminated. Thus, they can be reused directly without a decontamination treatment process. Results show that humic compounds complicated sediment treatment with cement. Therefore, cement did not present an appropriate binder for stabilising and solidifying the investigated sediments. Based on mechanical results, a mixture with 3% lime can be used as new road material.

“…More recently, there has been a growing interest in producing unfired bricks from recycled waste and by-product materials from the industry [1][2][3][4][5]. Compared with conventional fired clay bricks and ordinary Portland cement (OPC) concrete bricks, the production of unfired bricks from waste materials can significantly reduce the consumption of energy and emission of greenhouse gases [6].…”

In this study, attempts were made to use sandy soil as the main raw material in making unfired bricks. e sprayed-cured brick specimens were tested for compressive and flexural strength, rate of water absorption, percentage of voids, bulk density, freezing/thawing, and water immersion resistance. In addition, the microstructures of the specimens were also studied using scanning electron microscope (SEM) and X-ray diffraction (XRD) technique. e test results show that unfired brick specimens with the addition of ground-granulated blast-furnace slag (GGBS) tend to achieve better mechanical properties when compared with the specimens that added cement alone, with GGBS correcting particle size distribution and contributing to the pozzolanic reactions and the pore-filling effects. e test specimens with the appropriate addition of cement, GGBS, quicklime, and gypsum are dense and show a low water absorption rate, a low percentage of voids, and an excellent freezing/thawing and water immersion resistance. e SEM observation and XRD analysis verify the formation of hydrate products C-S-H and ettringite, providing a better explanation of the mechanical and physical behavior and durability of the derived unfired bricks. e results obtained suggest that there is a technical approach for the high-efficient comprehensive utilization of sandy soil and provide increased economic and environmental benefits.
