  • X-ray powder diffractometry of emissions from the cement

    Jan 01, 1989 X-ray powder diffractometry has been found capable of identifying and distinguishing limestone and cement particles, the two important emissions of the cement industry. The limestone shows strong reflections principally at 1.87,1.91,2.09,2.28,2.49,3.03 and 3.83 from its main constituent, calcite, whereas cement shows reflections at 1.76, 2

  • The Basics of Elemental Analysis with XRF - Materials Talks

    Jan 07, 2020 X-ray fluorescence spectroscopy is a powerful analytical technique that provides both qualitative and quantitative information on a wide variety of sample types including solids, liquids, slurries, and loose powders.It can quantify elements from beryllium (Be) up to americium (Am) in concentrations from 100% down to sub-ppm levels

  • Radiation Studies - CDC: Radiation from Building Materials

    Dec 07, 2015 Building materials that are made up of sandstone, concrete, brick, natural stone, gypsum, and granite are highly unlikely to contain radioactive material that will increase radiation dose above the low levels of background radiation we receive on a daily basis. Radioactive material in building materials may add to indoor radon levels

  • What Are The Different Types of Radiation?

    Mar 19, 2020 Gamma rays and x-rays can penetrate through the body. This is why they are useful in medicine—to show whether bones are broken or where there is tooth decay, or to locate a tumor. Shielding with dense materials like concrete and lead is used to avoid exposing sensitive internal organs or the people who may be working with this type of radiation

  • X-ray fluorescence - Wikipedia

    X-ray fluorescence (XRF) is the emission of characteristic secondary (or fluorescent) X-rays from a material that has been excited by being bombarded with high-energy X-rays or gamma rays.The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in

    the concrete mixture, placing plan, schedule, etc. This may result in savings, since the contractor will be motivated to produce and place the concrete at as low a cost as possible. This type of specification requires a higher level of effort by the contractor for QC. This contract type is also somewhat riskier for the

  • Mixing and Transporting Concrete - Penn State College of

    Many factors determine which type of transportation is most suitable. Type and constituents of the concrete mix, size and type of construction, topography, weather conditions (i.e. temperature, humidity, wind speed), location of the batch plant, and cost are all taken into consideration when choosing a mode of transport for your concrete

  • The Cement Manufacturing Process - Advancing Mining

    Aug 20, 2015 The overall value of sales of cement was about $8.9 billion, most of which was used to make an estimated $48 billion worth of concrete. Most construction projects involve some form of concrete. There are more than twenty types of cement used to make various specialty concrete, however the most common is Portland cement

  • The crypto-crystalline structure of C-S-H gel in cement

    Jul 01, 1987 In the samples used for the measurement of X-ray diffraction intensities of CH and gel, as referred to above, the tensile bending strength after 6 years was observed to be considerably reduced for the w/c 0.32 specimens, and partly also for the w/c 0.40 specimens, both in white cement and portland cement pastes, according to (11) and to FIG 3

    Jun 06, 2019 In other words, Gamma and X-ray are of primary concern. The ‘Alpha’ particle (another type of radiation from a nuclear explosion) is also highly dangerous but is hardly penetrable. It can be stopped by a single piece of paper, or an air filter (think of it as a heavy dust particle). It is carried by the wind currents and eventually falls to

ElvaX Plus spectrometer is used for quantitative and qualitative analysis of the cement samples elemental composition in a wide range of element concentrations. ElvaX Pro has the helium

  • Quantitative X-ray diffraction analysis in cement

    Sep 18, 2015 X-ray amorphous components like slags can be described using a pseudo-structure that fits the so-called “glass hump”, caused by the non-crystalline slag in the diffraction pattern background. Regular plant and cement type-specific definitions of the evaluation routine are necessary for reliable results

  • Analysis of cement - Understanding Cement

    The lost energy is radiated from the atom in the form of an X-ray. This process, in which one X-ray excites another X-ray, is called 'X-ray fluorescence'. The specimen of cement or other material may be in the form of a glass bead or a pellet of pressed powder
