Measuring the Size and Shape of Building Materials Measuring the Size and Shape of Building Materials Presentation Transcript

  • Measuring the Particle Size and Shape of Building Materials Ian Treviranus ian.treviranus@horiba.com www.horiba.com/us/particle© 2012 HORIBA, Ltd. All rights reserved.
  • What we’ll talk about Measurement technologies Application data Q&A© 2012 HORIBA, Ltd. All rights reserved.
  • Technologies in this Webinar LA-950 Laser Diffraction SZ-100 Dynamic Light Scattering & Zeta Potential CAMSIZER & CAMSIZER XT Dynamic Image Analysis PSA300 Static Image Analysis SA-9600 Flowing Gas BET Surface Area© 2012 HORIBA, Ltd. All rights reserved.
  • LA-950: Laser Diffraction Particle size performance leader Ninth generation Ultra durable Lowest total cost of ownership Suspension, emulsion, powder, paste, gel 10 nanometer – 3 mm© 2012 HORIBA, Ltd. All rights reserved.
  • Dynamic Range 0.01 – 3000 µm Widest wet measurement range Only system to measure 30 nm! 30 nm silica 40 nm latex© 2012 HORIBA, Ltd. All rights reserved.
  • Superior Dry Powder Feeder Direct flow of powder down to cell rather than turn 90o, then around plastic tube, no density restriction like horizontal units, zero impact surfaces means good dispersion w/o comminution Webinar TE016: Optimizing Dry Powder Measurements© 2012 HORIBA, Ltd. All rights reserved.
  • Superior Dry Powder Feeder Automatic control of sample feed rate LA-950 monitors amount of sample supplied by the vibratory feeder. Automatic feed back control keeps constant mass flow rate of powder during measurement This is CRITICAL – More reproducible, robust – No ghost peaks – No cutting off results – Fewer headaches! Unique to HORIBA© 2012 HORIBA, Ltd. All rights reserved.
  • CAMSIZER Series: Image Analysis High resolution size & shape Intelligent sieve correlation Patented dual capture CAMSIZER 30 micron – 30 millimeter CAMSIZER XT 1 micron – 3 millimeter© 2012 HORIBA, Ltd. All rights reserved.
  • Advantage of Image Analysis More Detailed Size Analysis due to Understanding of Particle Shape: Length, Width, Average Diameter© 2012 HORIBA, Ltd. All rights reserved.

  • Applications in this Webinar Cement Concrete Limestone/GCC/PCC/Dolomite Gypsum There are MANY others, but only so much time…© 2012 HORIBA, Ltd. All rights reserved.
  • General Importance for Powders Powder flow Particle size, Particle shape Dust hazard/nuisance Particle size Dissolution Particle size, Surface area Reactivity Particle size, Particle shape, Surface area© 2012 HORIBA, Ltd. All rights reserved.
  • Portland Cement Most common cement Particle size affects rate of hydration (1 um ~ 1 day, 10 um ~ 1 month) Set too fast, set too slow Fast expansion, poor strength Monitor size to control grinding process Historically measured using sieves and Blaine values Misleading© 2012 HORIBA, Ltd.

  • Cement Replacements Raw material cost and/or “green” costs Fly ash Slag (GGBS) *Housing and Building National Research Center, Egypt© 2012 HORIBA, Ltd. All rights reserved.
  • Cement Replacements Fly ash overlay with Portland cement using LA-950 PowderJet dry feeder© 2012 HORIBA, Ltd. All rights reserved.
  • Concrete Generally: cement + aggregate + water Size of cement affects hydration Size and shape of aggregate affects workability, compressibility Commonly use admixtures to control properties Plasticizers Pigments Accelerate/retard hydration Fumed silica© 2012 HORIBA, Ltd.
