Publication number: 20210025158Abstract: A structural, load-bearing panel useful in constructing multistory buildings may have a panel height, panel width, and panel thickness, and may include a first layer comprising at least 75 wt. % of concrete, relative to a total weight of the first layer; an insulation layer comprising flexible polymer, the insulation layer having a thickness of at least 5 cm; and a second layer comprising at least 75 wt. % concrete, wherein the insulation layer is sandwiched between the first and second layers, and wherein the panel is suitable to be set in any of a planar, curved, and polyhedral cross-sectional shape. Set panels are not flexible, though the flexibility of the insulation layer, particularly of a polyethylene foam, may allow the panel to have a curved, or polyhedral cross-section while still serving as a structural support.Type: ApplicationFiled: July 26, 2019Publication date: January 28, 2021Applicant: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Luai M.

Publication number: 20200355668Abstract: A system, device, and a method for determining a compound content in transformer oil are provided. The method includes positioning a syringe filled with transformer oil in the device to transfer the oil to a vial using the device. The device includes a stand, a threaded rod, a handle, a disc, and a syringe holder. The threaded rod is movable in a vertical direction by rotation of the handle and is configured to apply pressure via the disc on a plunger of the syringe positioned in the syringe holder to maintain an airtight connection between the vial and the device. The compound content is determined using a gas chromatograph by analyzing an aliquot extracted from a headspace gas of the vial.Type: ApplicationFiled: May 7, 2019Publication date: November 12, 2020Applicant: King Fahd University of Petroleum and MineralsInventors: Shafiqur REHMAN, Luai M.

Patent number: 10597328Abstract: A lightweight structural concrete formulation comprises a wet mix of about 460 kg/m3 of cementitious material such as ordinary Portland cement of which about 50 percent has been replaced by ground granulated basic furnace slag (GGBFS) and 7 percent by silica fume (SF) in other words the mix introduces between about 178 and 228 kg/m3 therefore the combination is good to produce secondary reaction products when the cement hydrates which produces secondary calcium silicate hydrate (C—S—H) which makes the structure dense and thereby increases its mechanical durability characteristics of the concrete product. Possible ratios of GGBFS and SF are 30-70 percent and 5-10 percent, respectively. By making the structures dense increases the mechanical and durability characteristics of the concrete product. Other ratios have been made including GGBFS of 30-70 percent and silica fume 5-10 percent, respectively.Type: GrantFiled: February 8, 2018Date of Patent: March 24, 2020Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Mohammed Ibrahim, Mohammed Salihu Barry, Luai M.
