Abstract: The present disclosure relates to methods for controlling the chemical composition of a first pozzolan by blending it with a different pozzolan having a different chemical composition. The method includes intimately mixing the two pozzolans and using a chemical analyzer to determine a chemical characteristic of the pozzolan fraction being produced. The output from the chemical analyzer is then used to control the blending of the first and second outputs to maintain the chemical characteristic within a desired range.

Abstract: Cement-SCM blends employ particle packing principles to increase particle packing density and reduce interstitial spacing between the cement and SCM particles. Particle packing reduces the amount of water required to obtain a cement paste having a desired flow, lowers the water-cementitious material ratio (w/cm), and increases early and long-term strengths. This may be accomplished by providing a hydraulic cement fraction having a narrow PSD and at least one SCM fraction having a mean particle size that differs from the mean particle size of the narrow PSD cement by a multiple of 3.0 or more to yield a cement-SCM blend having a particle packing density of at least 57.0%.

Abstract: Hydraulic cements, such as Portland cements and other cements that include substantial quantities of tricalcium silicate (C3S), dicalcium silicate (C2S), tricalcium aluminate (C3A), and/or tetracalcalcium alumino-ferrite (C4AF), 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.

Abstract: A safety cutting device includes a slidable insert that moves longitudinally within a cavity of a housing. The slidable insert has a cutting blade attached and moves within the housing from a safe position in which the blade is covered to an exposed position for cutting. The safety device has a release button positioned near an anterior end of the housing. A biasing member automatically retracts the blade when the release button is activated.

Abstract: A method for searching a database that includes private 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 ranking the search result items according to relevancy. The method also includes displaying at least a portion of the search results items as a selectable link where a first portion of the selectable links are to private network data and a second portion of the links are to public, non-social network data.

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.
