“…Based on trends in Figure 1, it can be concluded that the longer the curing periods, the greater the strength improvements. Xiao and Lee [12] reported that the strength of soft clayey soils increased significantly with curing period. As can be seen in Table 4.8, the rate of increment for each samples increased with curing periods.…”

Dredged marine soils (DMS) are considered as wastes and are currently not being recycled. Solidification of DMS needs to be undertaken before the materials can be reused.This study focused on the development of strength of three solidified fine-grained DMS which are high plasticity clay (CH), high plasticity silt (MH) and low plasticity silt (ML) admixed with cement and bottom ash. This paper discussed the effect of water-binder ratio and curing period on the strength development of the solidified DMS. The results show that the strength increased with prolonged curing. The strength increased when the water-binder ratio was decreased. CH samples with water-binder (w/b) ratio =1 has the highest strength that are up to 4.7 MPa. Optimal w/b ratio for solidified DMS is w/b=3.

“…Cement treated soil would really effect on the susceptibility to water, durability against freezing and thawing etc. Some of recent studies on cement treated soils, in addition to the above, would be mentioned as: stabilization of residual soil with rice husk ash and cement [15]; stabilization of clayey soils with high calcium fly ash and cement [16]; curing time effect on behavior of cement treated marine clay [17]; effect of cement treatment on geotechnical properties of some Washington state soils [18].…”

Soil-concrete is widely used to strengthen the foundation footings, in the construction of roads and railways, as well as for the production of bricks and pavement tiles. One of the most important physical and mechanical properties of soil-concrete is the compressive strength. We carried out a study of soil-concrete strength depending on its curing conditions and percentage of cement. For our study we used loam soil with the plasticity index of Ip = 12.3, Portland cement of type I, ground limestone with the specific surface of 4500 cm2/g, polycarboxylate based superplasticizer and water for mixing. Curing of samples was carried out in air-humid condition in wet sawdust and also with the thermal humid treatment in a steam chamber. It is experimentally established that the strength of soil-concrete depends not only on the ratio of clay aggregate and mineral binder, but also on the temperature and humidity conditions of curing. Additives of ground limestone and superplasticizer contribute to increase the compressive strength of soil-concrete. A mathematical model for determining the compressive strength of soil-concrete depending on the percentage of cement and the curing period is developed. This proposed mathematical model is advisable to apply for assessment of the compressive strength of soil-cement massive layer after the urgent repair of under-road pipelines.

“…For instance, some researchers performed a series of situ measurements and experimental analysises to study mechanical properties (e.g. UCS, shear strength, and stress-strain) of the cement-clay 6,15,29,[29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45] as a result of the mechanical stability is crucial for the cementclay structures. Also, some existing researches concentrated on studying the influence of the binder type and dosage, water content, and void ratio on the development of the hydraulic process within the treated clay 41,46,47 .…”

A thorough and comprehensive knowledge of the evolutionary pattern in the thermal-hydraulic-mechanical-chemical (THMC) behavior of cement-stabilized clay is essential for a more reasonable design of improved clay in practical engineering. Sensitive marine clays with low strength, reinforced by various cement contents (0%, 6%, and 12%), were produced as samples to study the evolutionary pattern of the THMC behavior of reinforced clays. Samples with designed curing times (1, 3, 7, 28, and 90 days) will be trimmed to the appropriate size and utilized in a series of mechanical tests. Furthermore, the other portion of the samples, which is pre-installed with sensors, is used to monitor the development in internal temperature, volumetric water content, suction, and electrical conductivity for 90 days. The results showed that the content of cement and curing time have a significant influence on the THMC behavior of reinforced clay. Meanwhile, the results indicate a strong coupling of the THMC behavior of clays reinforced by cement. The results will be of critical assistance in gaining advanced knowledge into the evolutionary pattern in the THMC behavior of reinforced clays as well as making a contribution to optimizing the stability, cost-effectiveness, and durability of the design of reinforced clays.
