Publication number: 20210371338Abstract: Integrally waterproof fiber cement composite materials including interior and exterior fiber cement articles for building structures are disclosed. Fiber cement formulations include small percentages of silica fume and silanol. Formulations may additionally include a cementitious binder, silica, and a density modifier such as calcium silicate or perlite. Advantageously, the addition of preselected small percentages of silica fume and silanol has been discovered to yield waterproofness at substantially lower concentrations of silica fume and silanol than would be required to yield waterproofness when using either silica fume or silanol alone.Type: ApplicationFiled: November 6, 2019Publication date: December 2, 2021Inventors: Noel Dones, Basil Naji, Caidian Luo

Patent number: 10239173Abstract: A cutting apparatus includes a cutting tool and a collection assembly designed for diverting, collecting and disposing dust generated during the cutting process. The apparatus includes a cutting tool, a collection assembly together with an optional dust separator and/or collection container. The air stream generated around the blade of the cutting tool during operation diverts the generated dust particulates into the collection assembly of the cutting tool. The air stream can also transport the dust into the dust separator which transfers the dust into the collection container, when present. Optionally, the collection container further includes an air filtration assembly for storing and disposing the dust.Type: GrantFiled: March 11, 2014Date of Patent: March 26, 2019Assignee: James Hardie Technology LimitedInventors: Benjamin Batres, Sam Kenneth LaBanco, Basil Naji, Gary Frank Prokop, William Edwin Venth, Matthew Spencer

Patent number: 8383031Abstract: A cementitious product and method of modifying the properties of a low or medium density FRC product by providing a predetermined pore size distribution. The pore size distribution is obtained such that in critical zones of the distribution, the pore volume is substantially equivalent to or less than the pore volume in a respective critical zone of a conventional high density FRC product. The resultant material provides improved properties over conventional medium density FRC products, in particular improved freeze/thaw durability and/or improved workability.Type: GrantFiled: June 30, 2011Date of Patent: February 26, 2013Assignee: James Hardie Technology LimitedInventors: Basil Naji, Donald J.

Publication number: 20080202389Abstract: A multiple mode cement set accelerating agent is provided. The accelerating agent includes a carrier fluid component having accelerator properties and CO2 gas sequestered in the carrier fluid. The accelerator components of the carrier fluid speed up the cement setting reaction. Additionally, CO2 gas is released from the carrier fluid during cement hydration to further accelerate the hydration reaction. In certain implementations, the carrier fluid is an alkanolamine solution and the cement set accelerating agent operates through a combination of alkali activation and carbonation. The multiple mode cement cure accelerating agent can be applied to pre-selected regions of green shaped cementitious articles to form partially cured zones in the article prior to curing of the green shaped article.Type: ApplicationFiled: March 21, 2005Publication date: August 28, 2008Applicant: James Hardie Internaitional Finance B.V.Inventors: Hamid Hojaji, Marcu H.

Publication number: 20070131145Abstract: A multi-function composition for incorporation into settable composite materials is provided. The composition is formulated as an additive to modify the density of the composite material and increase the rate of hardening or strength development of the material.
