Patent number: 11696925Abstract: Calcium hydroxide nanoparticles (Ca(OH)2NPs) synthesized using carob pulp extract may be hexagonal nanoparticles with a diameter ranging from about 31.22 nm to about 81.22 nm. The Ca(OH)2NPs may be synthesized by heating ethylene glycol, adding calcium hydroxide to the ethylene glycol to provide a first mixture, heating the first mixture, adding a carob pulp aqueous extract to the first mixture to form a second mixture, heating the second mixture, adding sodium hydroxide (NaOH) to the second mixture to form a third mixture, heating the third mixture, resting the third mixture at room temperature after heating, centrifuging the third mixture, collecting a colloid sediment, extracting any unwanted contaminants from the colloid sediment, and drying the colloid sediment to obtain Ca(OH)2NPs.Type: GrantFiled: September 14, 2020Date of Patent: July 11, 2023Assignee: KING SAUD UNIVERSITYInventors: Mohamad Saleh Alsalhi, Sandhanasamy Devanesan, Rawan Ibrahim Salem Alkhalaf, Hajer Saad Abdullah Allayed, Nasser Raqe Rashed Alqhtani, Mohammed Ghazi Alkindi, Osama Ghurmullah Mohammed Alghamdi

Patent number: 11435272Abstract: A method of determining shear strength of soil using a fall cone apparatus is provided. The method includes generating a first plot having graph lines defined for penetration depth values ranging from 4 to 20 mm on a first logarithmic paper, deducing a first mathematical model based on the first plot, and generating a second plot having the graph lines extended for a predefined penetration depth range based on the first mathematical model. The method further includes generating a third plot having graph lines corresponding to the extended penetration depth values defined for the W/A ratio values ranging from 0.17 to 13.3 on a second logarithmic paper, deducing a second mathematical model based on the third plot, generating a fourth plot having the graph lines extended for a predefined W/A ratio range based on the second mathematical model, and determining shear strength based on the fourth plot.Type: GrantFiled: January 19, 2022Date of Patent: September 6, 2022Assignee: KING ABDULAZIZ UNIVERSITYInventor: Mohammed Alghamdi
