  • RADIAL COAL ASH BASED MICRO-ARCHITECTURES AND METHOD OF SYNTHESIS
    Publication number: 20150321955
    Abstract: Microparticles having crystalline needle or rod-shaped structures of, for example, an ettringite mineral grown and attached radially from their surface. A method including nucleating and growing crystalline needles/rods from the surface of a particle in the presence of a solution of calcium, sulfur, and aluminum such as calcium sulfoaluminate, lime and calcium sulfate is described. One example is the radial growth of ettringite needles on the surface of fly ash particles in calcium sulfoaluminate-based cement paste and concrete.
    Type: Application

  • METHOD OF QUALITY CONTROL FOR DETERMINING THE COMPRESSIVE STRENGTHS OF GROUT IN MULTIPLE MOLDS
    Publication number: 20130263673
    Abstract: A method for testing compressive strength of multiple molds filled with a liquid settable grout wherein samples of the liquid settable grout are taken at selected filling intervals and poured into a container, and the container is sealed and the time, date and location information regarding the mold then being filled is recorded on the container. The sample container is then left in the same environment as the mold being sampled. A curve is generated which projects a final compressive strength based on compressive strengths at various cure times. The sample is removed from its container after a selected cure time and subjected to a series of Schmidt hammer tests, and these compressive strength readings are used to determine the projected final compressive strengths of the sample based on the cure time from the established curve.
