“…Clay develops swelling problems by contacting with water and moisture. 150 The clay's permeability was highly influenced by its connected pore space and water adsorption capacity; thereby, clay rapidly expanded and disturbed in-situ petrophysical properties resulting in its increased volume 151 and porosity. Thus, the process reduced both density and strength of clay.…”

The energy industry is exploring sustainable chemistry and engineering solutions for exploitation of shale reservoirs. Smectite-rich shale is challenging to drill with traditional water-based drilling fluid (WBDF). The objectives of this study are (i) to investigate acute toxicity of drilling fluids and (ii) to enhance the rheological properties, lubricity, and clay inhibition behavior of WBDF by adding Tween 80 (T80)/ZnO nanoparticles. Acute toxicity results revealed 100% survival rate of white leg shrimp in WBDF waste. At 0.7 g, the optimum concentration of T80ZnO, the plastic viscosity (PV) was improved by 12%; the negative surface charge of nanomaterial might have improved repulsion forces/stability and enhanced viscosity in the drilling fluids. Yield point (YP) was improved by 71%, moreover 10 min gel strength (GS) and 10 s GS were significantly increased by 32 and 54%, respectively. The metal oxide nanosolids induced heat transfer characteristics and ensured gelling and yield strength properties. Lubricity was slightly increased by 7%; the ZnO nanorods between the two sliding contact surfaces (i.e., assuming drill pipe and casing) improved lubricity. Filtrate loss (FL) volume was considerably minimized to 17 and 30% at API and high-pressure, high-temperature (HPHT) conditions, respectively; this observation could be explained by pores plugging in the filter paper. Heated clay swelling inhibition was optimized after addition of 0.6 g of T80ZnO nanoparticles to WBDF. The clay inhibition was enhanced by 9 and 17% when compared to conventional WBDF and fresh water, respectively; this progress might have attributed to the corresponding: (i) pores plugging in the clay and (ii) interparticle pores bridging between existing drilling additives and nanomaterial. The above findings identify that this drilling fluid could attain sustainable environmental and operational success while drilling into montmorillonite/smectite rich-clay and shale rock.

“…About 70% of conventional sand was replaced by Quarry dust in M20 concrete [22]. Quarry dust was used as a fine aggregate with coir pith as an alternative for river sand in M30 concrete [23]. Quarry dust can be used as an additive to stabilize soft soil in hydraulically bound pavement structures [29].…”

Exhaustion of locally available materials and increasing hauling charges gained the potential for the exploration of cost-effective alternative materials in the construction industry. Broad endeavours have been made over numerous years on the utilization of industrial waste, yet scant exploration is being done on ferrochrome slag. Ferrochrome slag is an industrial by-product obtained from stainless steel production. Several highway laboratory tests on the characterization of ferrochrome slag are carried out, and the physical and mechanical properties of ferrochrome slag are observed to fulfil MoRTH specifications. Deficiency of fines is observed in the gradation of ferrochrome slag, so quarry dust is incorporated for mechanical stabilization. Ferrochrome slag and quarry dust are blended in different proportions to check the gradation suitability as sub-base and base courses in flexible pavement. Modified Proctor Method of compaction is performed for the ferrochrome slag and quarry dust combinations to carry out the California Bearing Ratio (CBR) test at Maximum Dry Density (MDD) and Optimum Moisture Content (OMC). Studies have shown that the combinations of ferrochrome slag and quarry dust in 70/30 and 60/40 proportions are well graded and have reached the required gradation for use as cement-treated sub-base and base layers in flexible pavement.

Gene expression programming has been applied in this work to predict the California bearing ratio (CBR), unconfined compressive strength (UCS), and resistance value (R value or Rvalue) of expansive soil treated with an improved composites of rice husk ash. Pavement foundations suffer failures due to poor design and construction, poor materials handling and utilization, and management lapses. The evolution of sustainable green materials and optimization and soft computing techniques have been deployed to improve on the deficiencies being suffered in the abovementioned areas of design and construction engineering. In this work, expansive soil classified as A-7-6 group soil was treated with hydrated-lime activated rice husk ash (HARHA) in an incremental proportion to produce 121 datasets, which were used to predict the behavior of the soil’s strength parameters utilizing the mutative and evolutionary algorithms of GEP. The input parameters were HARHA, liquid limit ( w L ), (plastic limit w P , plasticity index I P , optimum moisture content ( w OMC ), clay activity (AC), and (maximum dry density (δmax) while CBR, UCS, and R value were the output parameters. A multiple linear regression (MLR) was also conducted on the datasets in addition to GEP to serve as a check mechanism. At the end of the computing and iterations, MLR and GEP optimization methods proposed three equations corresponding to the output parameters of the work. The responses validation on the predicted models shows a good correlation above 0.9 and a great performance index. The predicted models’ performance has shown that GEP soft computing has predicted models that can be used in the design of CBR, UCS, and R value for soils being used as foundation materials and being treated with admixtures as a binding component.
