Patent number: 10087107Abstract: A method of controlling the setting time of a geopolymer by coating aluminosilicate particles with nanoparticles to slow the geopolymerization reaction. The coating effectiveness of the nanoparticles may be enhanced by pretreating the aluminosilicate particles with a layer-by-layer assembly of polyelectrolytes. A geopolymer is formed by mixing about 39% to about 66% by weight aluminosilicate source, about 0% to about 40% by weight sand, about 19% to about 33% by weight of alkali activator solution, and about 1% to about 4% nanoparticles.Type: GrantFiled: February 2, 2017Date of Patent: October 2, 2018Assignee: Louisiana Tech Research CorporationInventors: Erez Allouche, Yuri Lvov, Carlos Montes, Anupam Joshi

Patent number: 9207155Abstract: A cured-in-place-pipe (CIPP) liner inspection system used to inspect a resin level in a CIPP liner that has been impregnated with resin using an inspection chamber having an optical sensor. The CIPP liner inspection system is also used to identify zones within an installed CIPP liner having lower mechanical strength due to inadequate distribution of resin using a robotic unit having an optical sensor. The optical sensor measures an optical property, which is used to determine a resin level or a mechanical property based on predetermined correlations between the optical property and the resin level and predetermined correlations between the optical property and the mechanical property.Type: GrantFiled: September 25, 2014Date of Patent: December 8, 2015Assignee: Louisiana Tech Research CorporationInventors: Erez Allouche, Shaurav Alam

Patent number: 8512468Abstract: A geopolymer mortar formed by mixing about 35% to about 45% by weight pozzolanic material, about 35% to about 45% by weight silicon oxide source, about 15% to about 20% by weight alkaline activator solution, and about 0.3% to about 2.5% by weight copper ion source. The pozzolanic material may be fly ash and the silicon oxide source may be sand. The alkaline activator solution may be a sodium hydroxide solution containing sodium silicate. The geopolymer mortar may have a viscosity in the range of about 25,000 to about 50,000 centipoise. The geopolymer mortar may be formed by further mixing one or more additives, such as surfactants, thermal spheres, anti-sagging agents, adhesion primers, or fibers. The geopolymer mortar may be applied as a protective coating on a surface of a structure.Type: GrantFiled: December 20, 2010Date of Patent: August 20, 2013Assignee: Louisiana Tech University Research Foundation, a division of Louisiana Tech University Foundation, Inc.Inventors: Erez Allouche, Carlos Montes
