“…Soil stabilization is the process of improving the engineering and index properties of poor soils (Kolias et al, 2005;Harichane et al, 2011). Numerous research studies have been conducted in the past to stabilize expansive soils by using various materials and admixtures (Katti, 1978;Estabragh et al, 2013;Bozbey and Garaisayev, 2010;Sharma and Hymavathi, 2016;Guney et al, 2006;Taye and Araya, 2015;Sharma and Sharma, 2019).…”

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 the largest effect was evident when adding crushed old concrete, as it reduced the settlement and increased the stiffness modulus, while the bricks showed less effect. The addition of CD materials to a highly plastic clay enhanced the strength substantially (Sharma and Sharma 2019). Moreira et al (2020) treated silty soil for use as a subgrade under pavement with 40-60% CD consisting of granular materials (sand and gravel).…”

Many countries suffer from the stacks of construction and demolition (CD) materials as they cause environmental and health problems in society. The city of Mosul in Iraq suffers from a huge amount of demolition materials resulting from destruction of most of the infrastructure. In the present study, attempts have been made to assess the influence of three types of CD materials (dragged asphalt, DA; crushed brick, CB; and crushed concrete, CC) on the response of a low-plasticity clay (CL) for use as a road subgrade layer. An intensive series of both experimental and numerical studies on the CL with 10% CD materials was carried out using field California bearing ratio (CBR) tests performed in a large-scale model box. The results showed significant improvement in the CBR values upon the addition of CD materials to the CL soil. The CBR values increased by 12.4, 13.7, and 49.7% with the addition of DA, CB, and CC, respectively. The CBR values improved between 1.1 and 1.7 times, corresponding to an increase in the layer thickness from 50 to 100 cm. Further increases in CBR values range from 1.5 to 1.8 times attendant with increasing the thickness of layer from 50 cm to 150 cm. The addition of CC is more active and gives higher CBR values. A good match was observed between the CBR values obtained from the experimental results and the numerical analysis using the PLAXIS 2D package.

“…e compacted stabilized soil blocks are different from fired earth bricks because it does not require brick kiln for the manufacturing of bricks which creates a lot of pollution. ey are composed of soil and stabilizers in the form of binders [2,3] or fibers, or a combination of both. e unfired admixed soil blocks have the potential to find their various applications in the field of civil engineering in the form of building blocks for the construction of walls, interlocking tiles for pavement, and other structures.…”

Unfired admixed soil blocks are composed of standard soil and a stabilizer or reinforcement material in the form of binder and fiber. This literature review systematically examines the performance characteristics of unfired admixed soil blocks made by using binders such as cement, lime, and other agricultural and industrial wastes available in the form of fibers and ash. A systematic search was carried out on Web of Science and SCOPUS using different keywords, and 313 records were found. After the screening and eligibility process as per PRISMA guidelines, 36 papers were eligible and hence selected to be reviewed and analyzed. This paper examines the performance characteristics of the blocks in terms of physical properties, mechanical properties, durability, microstructural evaluation, statistical analysis, cost analysis, energy consumption, and carbon dioxide emission. It was found that of the total 9 parameters considered for discussion, most of the studies using different admixtures (binder and fibers) in soil blocks were focused on compressive strength testing of blocks, water absorption, and durability by wetting drying cycles. However, other parameters like bulk density, maximum dry density and optimum water content, thermal conductivity, tensile strength, and flexural strength examined in recent studies are also reported in this paper. This systematic review proposes some research problems to be worked on various additional parameters like linear shrinkage, pull out test, erosion test, sorptivity test, porosity, efflorescence, water permeability, freeze/thaw test, and analysis of energy consumption and carbon dioxide emissions during the manufacturing of unfired admixed soil blocks using various binders and fibers for further study which the current literature lacks.
