Patent number: 8496750Abstract: A method for reducing the particle size of a pozzolanic material includes providing a pozzolanic material having an initial particle size and heating the pozzolanic material to cause a portion of the particles to at least partially fracture. Fracturing the particles creates a plurality of fissures that define sub-particles within the particles. The method also includes processing the fractured pozzolanic material to separate the sub-particles, thereby yielding the pozzolanic material having reduced particles.Type: GrantFiled: March 31, 2009Date of Patent: July 30, 2013Assignee: Staker & Parson CompaniesInventor: Alan D. McKee

Patent number: 8152080Abstract: Methods for comminuting the pozzolanic material include (i) providing a comminuting apparatus including a rotatable drum and an agitation medium positioned within the rotatable drum and configured to slidably move along the interior surface of the drum when the drum is rotated (ii) introducing a pozzolanic material into the comminuting apparatus and operating the comminuting apparatus so as to create a static charge on the agitation medium; and (iii) comminuting the pozzolanic material in the comminuting apparatus by rotating the rotatable drum without causing the media to crush the pozzolanic material so as to yield a reduced-size pozzolanic material comprising a majority of particles having a substantially globular shape.Type: GrantFiled: March 30, 2010Date of Patent: April 10, 2012Assignee: Staker & Parson CompaniesInventor: Alan D.

Patent number: 7975940Abstract: A system for reducing the particle size of a pozzolan includes a thermal fracture system and a defracturing apparatus. The system is highly efficient at drying and heating a natural pozzolan having a natural distribution of particle sizes. The system can create a reduced-size pozzolanic material with a desired particle size and particle morphology. The system for reducing the particle size of a pozzolan includes a thermal fracture system for heating and thermally fracturing the pozzolan and a defracturing apparatus that agitates the thermally fractured pozzolan to break the thermally fractured pozzolan apart.Type: GrantFiled: March 31, 2009Date of Patent: July 12, 2011Assignee: Staker & Parson CompaniesInventor: Alan D.

Publication number: 20100139523Abstract: Flowable concrete mixtures have an aqueous foam admixture mixed therein to give the concrete mixture desired strength, flowability, and density. The concrete mixtures include a hydration stabilizer to stabilize the aqueous foam. The hydration stabilizer inhibits the reaction between the hydraulic cement and the water in the aqueous foam. The aqueous foam can be stabilized using a fluorochemical surfactant.Type: ApplicationFiled: February 5, 2010Publication date: June 10, 2010Applicant: Staker & Parson CompaniesInventor: Lonnie James Gray
