“…The results of X-ray diffraction are presented in Table 4. The diffraction angle (2θ) at which compunds are located are in agreement with the literature [4,3,[36][37][38][39]. It can be seen from the comparison between intensities of peaks of XRD spectra that there is development of Ca(OH)2, CSH and Ettringite in C10QD mix after 7 days of curing.…”

Depleting good quality natural aggregates and soils call for the need of use of industrial by-products and waste materials in road construction. Use of wastes and by-products in road construction consume large quantities and resolve issue of their safe disposal. Class C fly ash is the by-product from thermal power plants while quarry dust is waste left behind during quarrying processes. This study investigated the application of class C fly ash and quarry dust mix for utilization in subbase layer of flexible pavement. The class C fly ash and quarry dust mixed were studied with the help of unconfined compressive strength test, repeated load triaxial test, durability test and microstructural analysis. The mixture of 90% fly ash plus 10% quarry dust was found to be suitable with respect to strength and durability criteria to be used as subbase material in flexible pavement. Owing to the formation of cementitious phases during pozzolanic reaction, proposed mix demonstrated significantly higher resilient modulus than conventional granular subbase material. The service life ratio for pavement with proposed mix is 1.2 and 1.26 in fatigue and rutting respectively compared to conventional pavement. The use of quarry dust and fly ash in large quantities in flexible pavement is an economical as well as sustainable solution for road construction.

“…Thermal spraying is a method of surface treatment by coating combining various techniques, namely oxyacetylene flame spraying [9][10][11][12][13], high-velocity spraying (HVOF) [14][15][16][17][18][19][20], electric arc spraying [21][22][23], atmospheric plasma spraying [24][25][26][27][28] and the cold spray process [29]. The different thermal spraying processes are defined mainly by the energy source used (combustion, electric discharge).…”

Inconel738 is a nickel-based super alloy widely used in manufacturing gas turbines, particularly in the manufacture of blades that are in direct contact with hot gases during their operation. As a result, these blades are subjected to high temperatures, significant static and dynamic stresses, erosion and/or hot corrosion which can be very severe. The use of coatings is one of the most effective strategies to protect materials against corrosion and increase the wear resistance of materials. In this study, β-Ni-Al coatings were sprayed onto an Inconel738 substrate using a wire flame spraying process and characterization of coating has been made.
