    Abstract

    January 28, 2016, 8:00am PT, 11:00am ET, 3:00pm GMT

    The relationship of particle size distribution (PSD) in cement and its impact on both strength and curing time of concrete make PSD critical to maintaining consistent product quality. Historically, sieves were the preferred method for determining PSD in cement. However, over the last 20 years, use of laser diffraction instruments have evolved into the preferred method for determining the distribution of particles in cement. This webinar will focus on unique features in the Beckman Coulter LS 13 320 that simplify sample preparation, decrease analysis time and improve accuracy. Accuracy data will be compared to NIST traceable SRM 114q to demonstrate the resolution of the Beckman Coulter LS 13 320.

    Learning Objectives:

    • Understand how use of laser diffraction instruments have evolved into the preferred method for determining the distribution of particles in cement
    • Understand unique features on the Beckman Coulter LS 13 320 laser diffraction particle size analyzer that simplify sample preparation, decrease analysis time and improve accuracy
