“…Figure 3 shows the stress strain characteristics of soil sample 1 treated with GGBS. It can be observed that, a steady rise in the peak zone of a curve with 60 days curing as the UCS value increased to 1725kPa.This is found to be in agreement with the reported data in literature [20] that slag replacement increased Kimmeridge Clay strength to a maximum at 28 to 60 days curing. Thus, the gradual failure of samples highlights the brittle nature of GGBS treated soil.…”

T he major decision in construction process involves the selection of suitable site with best soil conditions, as structure resides in the soil. Most problematic soils like expansive soils hardly proved to be the best engineering subgrade profile for pavement constructions. T hus, this has undeniably led to the soil improvement options accompanying the reduction in resource depletion and solid waste management. Therefore, soil stabilization technique opted in the treatment of expansive soils. In concern of all these facts in this study, an effort was made in investigating the viability of utilizing industrial waste Ground Granulated Blast furnace Slag (GGBS) and agricultural waste Groundnut Shell Ash (GSA) as stabilizing agents. Two soils of different swell characteristics were treated with varying percentages of GGBS (2.5, 5, 7.5, and 10%) and GSA (2, 4, 6, 8, and 10%) at different curing periods of 28 and 60 days. T he ascending behaviour of strength was experimentally analyzed by conducting Unconfined Compressive Strength and California Bearing Ratio (CBR) tests. T he uptrend in peak stresses coupled with improved CBR value implicated the efficacy of cost-effective waste materials in ascending the strength nature of the soil, thereby amplifying the growth of construction sector. Thus, this study catalyzed in enhancing the bearing strength of clayey soil; in this manner making it well suitable for multitudinous geotechnical applications.

“…The optimu m content of lime depends primarily on the type of soil and curing conditions [19].Previous engineering test results by other researchers have found that the optimu m lime-GGBFS rat io to achieve maximu m UCS is 1: 5 [ 17]. It was also suggested that this ratio o f a lime-GGBFS mixtu re is enough to activate GGBFS [45]. As shown in Figure 6, maximu m USC value is obtained in the sample which contains of 3% lime and 15% GGBFS.…”

“…So b lends of lime and GGBFS might be resistant to swelling caused by sulphate [44]. In addition, laboratory tests have shown a previously undemonstrated advantage where the incorporation of GGBFS co mbats the deleterious swelling which can occur when sulphate-containing soils are stabilised with cement or lime [45]. Higgins [19] showed that GGBFS was completely successful in reducing swelling caused by sulphate.…”

“…They also found that substitution of GGBFS for lime could significantly reduce swelling and Slag (GGBFS) M ixture for Stabilisation of Desert Silty Sands heave in the presence of sulphates. Higher percentages of replacement of lime with GGBFS, with only sufficient lime to activate the GGBFS, are the most effective in preventing sulphate attack [45]. The addition of GGBFS reduces the permeab ility of stabilised soil significantly wh ich has high permeab ility in natural state.…”

This study describes experimental results achieved on the use of Grand Granulated Blast Furnace Slag (GGBFS) and Lime in stabilising desert silty sand for possible use in geotechnical engineering applications, especially for roadways and railways constructions. The GGBFS and lime were added in percentages of 5, 10 and 15% and 1, 3, and 5% respectively, by dry weight of sand. Different laboratory tests such as mechanical aggregation test, hydrometer analysis, liquid-plastic limit , p H value test, compaction, unconfined compressive strength (UCS), California bearing rat io test CBR , were performed on samp les to understand the engineering characteristic of soil a nd influences of mixtures on the silty sand soil. The study results demonstrate significant imp rovements in unconfined compressive strength and Californ ia bearing ratio strength. Moreover the swelling behaviour of mixtures was decreased effectively. Thus mixture of GGBFS and lime can be suggested to improve engineering characteristic of desert silty sands.

“…Recently Wild and co-workers in a series of publications [9][10][11][12][13][14][15][16] showed that replacing a part of the lime by BFS in stabilization of a kaolinite greatly reduced expansion both for internal and external sources of sulfate. They also developed a hypothesis based on the gel theory of expansion.…”

A soil containing calcium sulfates was stabilized at 40°C, with ample moisture, by cementitious mixtures producing a range of calcium hydroxide upon hydration. Maximum expansion occurred when the stabilizing agent was lime, whereas a mixture containing portland cement, Class C fly ash, and an amorphous silica stopped the expansion. X‐ray diffraction peak width and scanning electron microscopy (SEM) based image analysis showed that maximum expansion correlated with crystallization of colloidal ettringite. Ettringite was seen by SEM within an hour of mixing the soil with lime. Colloidal ettringite was not observed when portland cement, with supplementary cementing materials, was used for stabilization.
