Appl. No.:

12/576117

Inventors:

John M. Guynn - Salt Lake City UT, US
Andrew S. Hansen - Bountiful UT, US

Assignee:

Roman Cement, LLC - Bountiful UT

International Classification:

C04B 14/04
C04B 18/06

US Classification:

106705, 106DIG 1

Abstract:

A high early strength pozzolan cement includes larger sized pozzolan particles and smaller sized hydraulic cement particles which contain tricalcium silicate (e. g. , Portland cement). Particles larger than 10 μm are predominantly (50%, 65%, 75%, 85% or 95%) pozzolan particles, and particles smaller than 10 μm are predominantly (50%, 65%, 75%, 85% or 95%) hydraulic cement particles. Excess calcium from the hydraulic cement forms calcium hydroxide available for reaction with the pozzolan particles, optionally in combination with supplemental lime. At least 30%, 40%, 45%, 55%, 65% or 75% of the pozzolan cement (combined pozzolan and hydraulic cement particles) consists of pozzolan, and less than 70%, 60%, 55%, 45%, 35% or 25% consists of hydraulic cement.

US Classification:

Abstract:

A high early strength pozzolan cement includes larger sized pozzolan particles blended with smaller sized hydraulic cement particles containing tricalcium silicate and/or dicalcium silicate (e. g. , Portland cement). Excess calcium release from the hydraulic cement when mixed with water forms calcium hydroxide available for reaction with the pozzolan. The fineness of the hydraulic cement particles is substantially greater than the fineness of the pozzolan particles (e. g. , about 1. 25 to about 50 times greater). Reducing or eliminating coarse hydraulic cement particles that cannot fully hydrate but include unreacted cores reduces or eliminates wasted cement normally found in concrete. Replacing some or all of the coarse cement particles with pozzolan particles provides a pozzolan cement composition having significantly lower water demand compared to the hydraulic cement by itself.

Abstract:

A method for searching a database that includes private social network data includes providing one or more databases including a plurality of database entries, a first portion of the database entries including private social network data and a second portion including non-social network data that is publicly accessible on the World Wide Web. The method further includes receiving a keyword search request from a search request user and searching the one or more databases or a keyword index thereof using one or more keywords and determining a hierarchy for search result items. The method also includes displaying at least a portion of search results items according to the hierarchy. And, determining whether the user has access rights to a particular subset of the private social network data and wherein if the user has access rights to the particular subset of private social network data, using at least a portion of the particular subset of social network data in the step of (i) searching the one or more databases, (ii) determining the hierarchy, and/or (iii) displaying the search result items.

Abstract:

Methods for accurately comparing the levels of ionizable lipids in two cell populations that differ in some respect from each other using mass spectroscopy and isotopic labeling are provided. The methods can be used to identify a change in a lipid of interest in response to a cellular, chemical, genetic, or environmental change to the cell population (i. e. , a lipid response to a cell perturbation). The change in the lipid of interest can be a change in composition, rate of synthesis, and/or location of the lipid.

US Classification:

705319, 705 11

Abstract:

A method for generating a database of activities associated with places of interests having names that are non-descriptive of the activity includes, providing a social network that includes a plurality of unique users, each user having a social network user account; providing a social network user interface for creating a place of interest entry, wherein the user input interface requests from the social network user an activity that can be performed at the place of interest; for each of the plurality of unique users creating a plurality of places of interest entries by (i) obtaining a location of the place of interest having a name or type of a place of interest (POI) associated therewith; and (ii) receiving from the particular user, an activity that can be performed at the place of interest, wherein the name or type of the place of interest is non-descriptive of the activity that can be performed at the place of interest. In addition, the method includes, for each of the place of interest entries, storing the location, the activity, and optionally the name or type of the POI in a relational database.

US Classification:

Abstract:

A high early strength blended cement composition includes larger sized fly ash and/or natural pozzolan particles blended with smaller sized hydraulic cement particles containing tricalcium silicate and/or dicalcium silicate (e. g. , Portland cement and/or ground granulated blast furnace slag). Excess calcium released from the hydraulic cement particles when mixed with water forms calcium hydroxide available for reaction with the fly ash and/or natural pozzolan. The fineness of the hydraulic cement particles is substantially greater than the fineness of the fly ash and/or natural pozzolan particles (e. g. , about 1. 25 to about 50 times greater). Reducing or eliminating coarse hydraulic cement particles that cannot fully hydrate but include unreacted cores reduces or eliminates wasted cement normally found in concrete. Replacing some or all of the coarse cement particles with coarse pozzolan particles provides a blended cement composition having significantly lower water demand compared to the hydraulic cement fraction by itself.

Abstract:

Hydraulic cements, such as Portland cements and other cements that include substantial quantities of tricalcium silicate (CS), dicalcium silicate (CS), tricalcium aluminate (CA), and/or tetracalcalcium alumino-ferrite (CAF), are particle size optimized to have increased reactivity compared to cements of similar chemistry and/or decreased water demand compared to cements of similar fineness. Increasing hydraulic cement reactivity increases early strength development and release of reactive calcium hydroxide, both of which enhance SCM replacement and 1-28 day strengths compared to blends of conventional Portland cement and one or more SCMs, such as coal ash, slag or natural pozzolan. Decreasing the water demand can improve strength by decreasing the water-to-cement ratio for a given workability. The narrow PSD cements are well suited for making blended cements, including binary, ternary and quaternary blends.
