Experimental datasets on engineering properties of expansive soil treated with common salt

Abstract

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.

Geotechnical Properties of Lateritic Soil Stabilized with Periwinkle Shells Powder

“…Meanwhile, (PSP) liquid limit dropped at 4 and 6 %, plastic limit dropped at 10 % and plasticity index at 6 % respectively. The finding of the study is similar to that of [27]. Table 3 and figure 3 showed that the maximum dry densities of the lateritic soil increases as the percentages of the stabilization agent increases, however at 6%, Periwinkle Shell Powder reached the peak MDD as further addition of 8% and 10% PSP led to a reduction in the soil MDD to 1892.46kg/m3 and 1867.80kg/m3 respectively.…”

“…However, in view of using a sustainable stabiliser that will be cost effective and eco-friendly [26][27] used common salt to stabilised expensive soil and noticed that the addition of 1.5 % of common salt to the weight of expansive soil decreased the swelling behaviour but improve the strength quality of expansive soil, thereby made the treated soil more stabilized.…”

Experimental datasets on compliance level to minimum standard requirements among sandcrete block manufacturers in South Western Nigeria

“…These results were then compared with the minimum standards. The data presentation is similar to that of [1] , [21] , while safety procedures recommended in [22] , [23] , [24] were strictly followed in preparing the control samples.…”

Experimental datasets on properties of river sand as an aggregate in replacement of crushed rock for interlocking stones production

“…The outcome of the strength test revealed the performance and standard of local building materials in low cost housing production [19] , [20] . The presentation of data is also similar to that of [21] , the experimental procedure of data presented took into consideration the recommendations of [22] , [23] , [24] .
