“…With a high purity of amorphous SiO 2 with significant volcanic ash activity, PA had been considered one of the most promising renewable resources. Thus, PA is believed to be of great potential for application in the construction industry, in line with the concept of sustainable green building [29][30][31].…”

This research aims to investigate the potential of engineering waste marine silt stabilized by a self-developed stabilizing chemical additive called PZ-1 as a subgrade filler. PZ-1 is composed of calcium carbide residue (CCR) and plant ash (PA) under an optimal composition ratio determined by coupling particle swarm optimization with a support vector machine (PSO-SVM). The effect of curing agent dosage (wg), temperature (wT), number of dry-wet cycles (Ndw), and organic matter content (wo) on the micro-macro behavior of the stabilized silt were investigated via the unconfined compressive strength (UCS) test, the scanning electron microscope (SEM) test, and the X-ray diffraction (XRD) test. The experimental results demonstrate a significant positive effect of PZ-1 on the unconfined compressive strength (qu) of marine engineering waste silt with curing agent contents of 0~8%. It was also found that strength improvement of the stabilized silt can be attributed to the formation of gelling substances such as C-S-H and calcite. The water resistance of the stabilized silt can be enhanced by increasing the dosage of the curing agent. Moreover, the organic matter content and ambient temperature have significant effects on the dry-wet cycle tolerance of solidified soil, among which temperature exhibits a more obvious impact.

“…Expansive soil shows swell-shrink behavior near the ground surface due to the land covered by expansive soil [6,7]. These soils occupy approximately 8.9×10 km 2 in India; approximately one-fifth of their surface area covers the states of Maharashtra, Gujarat, Uttar Pradesh, Madhya Pradesh, Rajasthan, Andhra Pradesh, Geotechnical Properties and Stability of Expansive Soil using Fly Ash Farhan KHAN et al http://wjst.wu.ac.th and Tamil Nadu [8,9]. Black cotton soil is composed of fine-grained soil or decomposed rocks that show huge volume change when subjected to variability in moisture content; expansive soil shows swell shrink behaviour near the ground surface due to direct contact with variation in seasons and environment [10,11].…”

This study was conducted to have a detailed analysis of the geotechnical properties of expansive soil and fly ash from Sipat thermal power plant. It reported the findings of laboratory studies on certain common physical and geotechnical properties. The chemical properties and morphology of the black cotton soil (BCS) and fly ash is also determined using scanning electron microscopy and X-ray diffraction test. The geotechnical test includes determining specific gravity, particle size distribution, moisture content, standard proctor test, free swell index, and Atterberg’s limit. The different compositions of expansive soil with fly ash, yellow soil, moorum, and sand are studied. BCS was evaluated with fly ash, fly ash and sand, BCS with yellow soil, and moorum and fly ash. The study also analyzed the details and results of different tests conducted on soil samples. The results showed that strength and fly ash are inversely proportional; as fly ash increases, strength decreases, and vice versa. Fly ash was added from 20 to 80 % by replacing expansive soil by weight. The results indicated that expansive soil can be stabilized by the addition of fly ash to a limit of 10 to 20 %. HIGHLIGHTS The XRD And SEM results shows the mineral present in the FlyAsh and Expansive soil The geotechnical properties of Flyash and expansive soil is determined The OMC increases with decrease in densities The Particle size distribution curve shows the soil is GW soil GRAPHICAL ABSTRACT

Bentonite clay is the soil that undergoes high volume changes (swelling) when its moisture content increases. The soil swelling may cause structural damage leading to damage to structural members like cracking in reinforced foundations and borders, curbs swelling, and eventually produces deformation indoors and on floors. In this study, Bentonite clay with expansive characteristics was used and mixed with various amounts of Pulverized waste glass PWG (0%, 5%, 10%, and 15%). Two types of PWG were prepared: fine glass (passing sieve No. 200) and coarse glass (passing sieve No. 2 mm). Laboratory experiments were performed on Bentonite specimens blended with different amounts of PWG. The results showed that the addition of 15% by Bentonite weight of 2 mm of PWG reduces the Atterberg limits considerably. Moreover, a noticeable reduction was observed in the Bentonite samples' free swell and swelling pressure after being treated with different amounts of PWG. The observed advantages of adding the PWG to Bentonite clay soil by decreasing the volume changes and enhancing the overall properties of Bentonite clay reflect the suitability of using PGW as a good soil stabilizer. Besides reducing the impact of waste glass on the environment due to its non-biodegradable nature.
