  • Research on Crushing Concrete Members by High

    May 24, 2021High-voltage pulse discharge (HVPD) is an energy-saving, efficient, and green technique, which has broad prospects in concrete crushing. The finite element models of the concrete beam, slab, and column segments were established with ANSYS/LS-DYNA finite element software. Based on the principle of equal impact pressure, the shock wave generated by the fuse explosion caused by HVPD

  • How Much Does Crushed Concrete Cost?

    Aug 15, 2018When crushed concrete is charged by the ton, the price can vary anywhere from $6 to $14 per ton. By the yard, crushed concrete can cost anywhere from $20 to $30. Generally, the more you purchase, the lower that price will be per yard or ton. Mainslandscapesupply, for example, sells its crushed concrete from $22.95 to $24.95.

  • Concrete

    Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past, lime based cement binders, such as lime putty, were often used but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual

  • The History of Concrete

    The time period during which concrete was first invented depends on how one interprets the term "concrete." Ancient materials were crude cements made by crushing and burning gypsum or limestone. Lime also refers to crushed, burned limestone. Modern Portland cement is manufactured to detailed standards. Some of the many compounds found

  • Subgrades Subbases for Concrete Slabs

    Concrete strength also comes into play, but most slab concrete is around 3000 to 4000 psi, so it's not a major factor. The tensile strength of concrete is typically taken as 10 to 15% of the compressive strength, so only about 400 or 500 psi. Compare that to the tensile strength of Grade 60 rebar, which is 60,000 psi.
