what is pulverized concrete

  • Pulverised Concrete

    It’s claimed that most of the concrete was reduced to tiny 1060 micron particles, but there’s no clear explanation of how this figure is derived, either And there is some disagreement on this While Dr Steven Jones has described concrete being pulverised to “flourlike powder”,

  • 911 Research: Concrete Pulverization

      Each one is 39" thick; the top 4" is a poured concrete slab, with interlocking vertical steel trusses (or spandrel members) underneath This steel would absorb a lot of kinetic energy by crumpling as one floor fell onto another, at most pulverizing a small amount of concrete where the narrow edges of the trusses strike the floor below

  • The Use of PFA in Structural Concrete

      It must be said, however, that PFA concrete is more sensitive to water content and initial curing than conventional concrete, so that extra care must be taken in supervision of its production and curing, but the benefits available are worth the extra effort 8 In its early days PFA concrete is generally a darker colour than plain OPC concrete, and
