Stimulation Behaviour Study on Clay Treated with Ground Granulated Blast Slag and Groundnutshell Ash

Abstract

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.

Recent Trends in Stabilization of Expansive Soil using Calcined Clay

“…Traditional admixtures like lime [16], cement [17] and its byproducts have stabilized the problematic nature of expansive soil and helped to improve the strength characteristics of soil but that leads to the depletion of natural resources. So upcoming research are done by adding industrial by-products such as GGBS [18,19], flyash [15,20,21], phosphogypsum [22], Dolochar [23] etc and agriculture waste such as groundnut shell ash [24][25][26], bagasse ash [27,28], etc. This admixture improves the strength, drainage, and permeability characteristics of the soil.…”

The Effect of Heat on the Settlement Properties of Cement-stabilized Clay Soil

“…The ever-increasing expansion of construction and building, and lack of access to suitable sites have led humans to utilize sites with inappropriate engineering properties. Generally, the soil in most construction sites is not entirely capable of bearing the weight of the structure [1,2]. The mechanical properties of soil are determined by various factors, including soil texture, moisture, volumetric density, grain distribution, shape and mineralogy, interlocking of grains, grain adhesion and chemical weathering, grain cohesion mechanisms, and presence of vegetation.…”
