“…Several studies has been done on the available additives to stabilized expensive soil due to its change in moisture contents and problematic in nature that causes soil to either shrink or swell under loading [1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20]. However, studies conducted by [7], [8], [9], [10] established the addition of different percentages of sodium chloride as additive for stabilizing expansive soils.…”

Construction of highway pavements or high rise structures over the expansive soils are always problematic due to failures of volume change or swelling characteristic experienced in the water permeability of the soil. The data in this article represented summary of (Durotoye et al., 2016; Durotoye, 2016) [1], [2]. The data explored different percentages of sodium chloride as additive in stabilizing the engineering properties of expansive soil compared with other available stabilizer previously worked on. Experimental procedures carried out on expansive soil include: (Liquid limit, Plastic limit, Plasticity index, Shrinkage limit, Specific gravity Free swell index and Optimum water content) to determine the swelling parameters and (maximum dry density, California bearing ratio and unconfined compressive strength) to determine the strength parameters. The results of the experiment were presented in pie charts.

“…The failure of engineering structures founded on problematicgeologic units such as clay and unconsolidated sandy materials is common in some parts of Nigeria [27] [14]. Many times, engineers, planners, designers and contractors give wrong recommendations and specifications because they are not at home with the properties and behaviors of the materials they use for certain projects.…”

Little to none has been known about some soils excavated for backfilling purposes in Anambra State, Southeastern Nigeria. Thus, this study, which involved literature reviews, field sampling, and integrated geotechnical analyses, presents an assessment of their engineering properties and suitability as backfill (foundation, embank subgrade, and base) materials. Eight soil samples (ABG, NIM, OZB, NKA, OKJ, ORK, ULI, and NBI) from eight borrow pits were studied. Grain analysis revealed that the eight soils are dominantly composed of medium-coarse grains. Laboratory USCS identified and grouped the soils into five SW, SP, SC and CL. Their permeability coefficients ranged from 4.22x10-6 to 4.34x10-4 m/sec, hence they are permeable. Compaction test revealed MDD range of 1.76-1.94g/cm 3 , OMC range of 13.29 bulk density range of 1.68-1.90g/cm 3. Their specific gravity ranged from 2.55-2.69. The soils have low natural moisture content, ranging from 1.61 Atterberg limits of the fines showed that they are nonplastic to low plastic materials, with the highest PI as 12% (for the CL soil). The soils have low cohesion (0.66-6.72kPa) but high frictional angle (32.54 36.47 o), except for the CL soil which has 27.31kPa cohesion and 19.34 o friction angle. From the findings, it was deduced that, generally, these soils are g backfilling materials, though to varying degrees (SW˃GP˃SP˃SC˃CL), because of differences in their engineering properties. However, factors that could alter their good characteristics and suitability were discussed and recommendations given.
