“…The reduction in both the limits may be because of the addition of coarser material to clayey soil. A similar reduction in liquid and plastic limit on addition of WFS to clayey soil has been observed (Dong et al, 2013;Jain et al, 2015;Kale et al, 2019). On adding 5, 10 , 15 and 20 per cent molasses to clayey soil, both liquid limit and plastic limit decreased (Figure 8) which ultimately reduced the plasticity index.…”

“…Mgangira and Jones (2006) described that WFS has good properties which can alter the properties of poorly graded soil to those of well graded soil. Dong et al (2013) blended WFS in waste heavy clay and reported that with the increase in proportion of foundry sand, the plasticity and cohesion decreased. The mixtures of clay and foundry sand can be used as suitable construction fill material with sand content up to 66 per cent.…”

“…On adding WFS up to 20 per cent to clayey soil, the DFS value reduced to 0; the further increment of WFS to clayey soil did not show any change to DFS value and it remained zero. The reduction in DFS value on addition of WFS may be attributed to the increased content of coarser particles (responsible for reduction in surface activity) in clayey soil (Kale et al, 2019;Dong et al, 2013). The addition of 10 per cent molasses to clayey soil reduced the DFS value to 0 and further increment of molasses to clayey soil did not affect the DFS value.…”

Purpose The purpose of this paper is to attempt to use two industrial wastes; waste foundry sands (WFS) and molasses (M) along with lime (L) to improve the strength characteristics of clayey soil. Design/methodology/approach In the first part of the study, the optimum percentages of materials (WFS, molasses, lime) have been found out by conducting differential free swell (DFS) and consistency limit tests on clayey soil by adding various admixtures. The second and third part of the study investigates the compaction behaviour and unconfined compressive strength (UCS) of clayey soil on addition of optimum amount of various materials alone and in combination with each other. Finally, the micro-structural behaviour of addition of optimum percentages of lime, WFS and molasses using Scanning electron microscopic technique has been discussed. Findings The laboratory results revealed that the addition of optimum content of lime along with WFS and molasses reduced DFS and plasticity index and increased maximum dry density and UCS values. The microstructural behaviour showed that the presence of lime and molasses filled the voids present in the soil and the addition of WFS helped in providing compact structure, thus improving the strength characteristics. Practical implications The study will be helpful in designing low-cost pavement designs for rural roads. Social implications The adverse effect of waste materials on environment may be solved by using them in improving the strength characteristics of clayey soils, thereby providing healthy environment to living beings. Originality/value The study will help to provide low-cost methods to improve strength characteristics of clayey soil along with the use of waste materials; the disposal of whose is a challenging task.

“…The results showed that there was a significant soil improvement on the California Bearing Ratio, Unconfined Compressive Strength and Triaxial Value. Research [6] on the use of two industrial wastes, namely heavy clay waste and Foundry Sand Blends as construction materials reported an increase in friction angle through direct shear test. This research used two types of waste with a special compound as a soil stabilizer mix to replace lime.…”

A problem that often occurs in industrial areas is roads damage that are caused by the low carrying capacity of their subgrade as well as by over capacity of heavy vehicles passing through those roads. A lot of waste that is produced in industrial areas, which also another problem, can be used as soil stabilizers. This study proposed a method using industrial waste as stabilization material to improve the carrying capacity of the soil. Testing materials are prepared for both original and stabilized soil using three types of industrial waste, namely Silica Sand waste, and Dust Sand Foundry. One of mechanical property tests, i.e., direct shear test, was conducted with different percentage of waste for each sample. Result showed that there was 36.8% increase in the internal shear angle of the modified soil with 2.5% Dust Sand Foundry additives without the addition of Silica sand waste compared to the internal shear angle of the original soil.
