Despite not being detected in the elemental chemical composition experiment, the significant element in the chemical formula of kaolinite, Al2(Si2O5)(OH)4, is aluminum (Al).
Unlike other types of clay, aluminum (Al) was notably missing from the composition of the anthill clay.

Yamashita et al. [6] performed a FE simulation when a physics-based deformable tire–soil interaction was fully integrated into a monolithic multibody dynamics computer algorithm.
Wasfy et al. [7] simulated a high-fidelity model for a tire interaction with hard ground.
Wang et al. [16] developed a 3D finite element model to study the mechanical response of asphalt pavement under dynamics loads.

From the point of view of the analysis of the authors who publish most cited papers (Fig. 4), the results show how the most cited paper on the topic was published in 2018 from Huang et al. on Resources, Conservation and Recycling [36] with 158 citations, followed by Gàlves-Martos et al. [37] with 154.
In this regard, Aslam et al. [41] defined the interaction between stakeholders as a key suggestion for improving CDW management; · to define integrative strategies to minimize waste.
In particular Ruiz et al. [17], highlighted the need to identify strategies in reference to each of the five lifecycle stages of construction and demolition activities.

Silver nanoparticles are also used in clothing, food industry, sunscreens and cosmetics (Vigneshwaran et al. 2007).
So they are being projected as future generation antimicrobial agents (Raveendran et al. 2003).
In particular, silver nanoparticles are proved to have potential antibacterial, antifungal and antiplasmodial and larvicidal properties (Saxena et al. 2010; Elumalai et al. 2010).Very recently green silver nanoparticles have been synthesized using various natural products like green tea (Camellia sinensis) [Vilchis-Nestor et al. 2008], neem (Azadirachta indica) leaf broth (Shankar et al. 2004), natural rubber (Abu Bakar et al. 2007), aloe vera plant extract (Chandran et al. 2006), leguminous shrub (Sesbania drummondii) (Sharma et al. 2007), latex of Jatropha curcas (Bar et al. 2009), Ocimum sanctum (Ahmad et al. 2010), Eclipta prostrata (Rajakumar and Rahuman 2011), Pongamia pinnata (Raut et al. 2010, Euphorbia hirta leaves extract (Agalya Priyadharshini et al 2012).
It is reported that the plant extract have anti-allergic, anti-inflammatory (Lanhers et al. 1991), antimicrobial (Akinrinmade et al. 2010), diuretic and antidiabetic activity (Johnson et al. 1999).
