“…These latter, have the ability to retain water within the flocculated structure which leads to an increase in the water content. The same result has also been reported by [34,35]. However, increasing lime percent more than 2% leads to decrease the liquid limit with an increase of plasticity for the two treated samples.…”

Abstract. Clay soils are known for their water sensitivity, which causes irreparable damage to any structure built on this type of soil. In order to avoid such problem, it is necessary to use various improvement and stabilization methods such as treatment with lime. This process has been used successfully in the field for decades. The addition of lime generates various physicochemical reactions within the soil such as cation exchange and pozzolanic reactions which are largely responsible for the improvement of the soil in question. This paper presents a study concerning the variation of physicochemical properties of clayey soil with the addition of quicklime at different percentages. Experiments were performed on two clayey soils (CL type) in order to investigate the influence of quicklime on Atterberg limits and pH. These tests were carried out in an attempt to study and follow the development and progression of various reactions occurred within the soil with various lime percentages. The results show that the addition of quicklime causes a significant improvement in soil properties by reducing plasticity and thereby improves the soil workability. It can also be found that the addition of lime increase pH of soil, which allow activating pozzolanic reactions who tend to stabilize the soil in question by formation of cementitious compounds. Finally, the pH can be considered as a relevant parameter who allows a better understanding of the reactions that occur in the soil matrix.

“…In the pozzolanic reaction chemical bonds develop between adjacent cement grains surfaces and interfaces between cement grains and soil particles. In cohesive soils cement hydration develops strong linkages between the minerals and the aggregates to form a honeycomb type structure whereby the particles of soil can no longer slide over each other (Chew et al, 2004). Therefore, not only cement reduces the plasticity of soil, but it also increases the strength and reduces the water holding ability of cohesive soils (Tang et al, 2007and Estabragh et al, 2016and 2017.…”

“…This shows the flocculated nature of the fabric in the matrix of stabilized soil samples. The flocculated fabric can be attributed to the cation exchange process that results in replacement of calcium ions with exchangeable ions such as potassium and sodium (Chew et al, 2004). The formation of reticulate and needle shaped hydration products which occupy the large pres and enhance cementation bonding of soil particles (Chew et al, 2004).…”

Mechanical and Leaching Behavior of a Stabilized and Solidified Anthracene-Contaminated Soil

This paper presents an investigation into remediation of an anthracene-contaminated clay soil through experimental tests. Samples were prepared of uncontaminated and contaminated soil-cement with 20 and 30% cement. Unconfined compression tests (UCT) were conducted on the natural soil and soil contaminated with anthracene. In addition, similar tests were carried out on uncontaminated and contaminated soil-cement at different curing times. Leaching tests were also conducted on contaminated soil and

“…The curing time also has an effect on the specimens in consolidated-drained triaxial compression test, with a longer curing time leading to a lower strain to peak strength and higher peak strength for the specimens [10]. The 7-day strength increases almost proportionately with the cement content throughout the range of cement content investigated in the test of unconfined compressive strength of treated clays [17]. As reported by [18], cement-treated Singaporean marine clay showed significant curing effect in the physical properties, unconfined compressive strength and compressibility characteristics, such as the decrease of compression index (Cc) with longer curing period.…”

Abstract. Great quantities of dredged marine soils (DMS) have been produced from the maintenance of channels, anchorages and for harbour development. DMS have the potential to pose ecological and human health risks and it is also considered as a geowaste. Malaysia is moving towards the sustainability approach and one of the key factors to achieve it is to reduce waste. Thus, this geowaste should be generated as a new resource to substitute soil for civil works such as for land reclamation and backfilling. This shows the improved settlement of consolidation in treated DMS. DMS is referred to as a cohesive soil which includes clayey silt, sandy clay, silty clay and organic clay. This type of soil has low strength and high compressibility. The objectives were achieved through literature review analysis and also laboratory test which was one dimensional oedometer test. On the other hand, treated DMS with more ground granulated blast furnace slag (GGBS) gives a lower settlement compared to specimen with higher percentage of cement in a treated soil. Thus this shows that cement content can be reduced in soil solidification when GGBS is added. The optimum binder ratio found was 3:7 where 3 is cement and 7 is GGBS.
