  2. Concrete cone failure - Wikipedia

    en.wikipedia.org/wiki/Concrete_cone_failure

    Concrete cone is one of the failure modes of anchors in concrete, loaded by a tensile force. The failure is governed by crack growth in concrete, which forms a typical cone shape having the anchor's axis as revolution axis .

  3. Size effect on structural strength - Wikipedia

    en.wikipedia.org/wiki/Size_Effect_on_Structural...

    For this reasons, the size effect on the strength in brittle failures of concrete structures and structural laminates has long been ignored. Then, however, the failure probability, which is required to be < 10 − 6 {\displaystyle <10^{-6}} , and actually does have such values for normal-size structures, may become for very large structures as ...

  4. Concrete slump test - Wikipedia

    en.wikipedia.org/wiki/Concrete_slump_test

    The test is carried out using a metal mould in the shape of a conical frustum known as a slump cone or Abrams cone, that is open at both ends and has attached handles.The tool typically has an internal diameter of 100 millimetres (3.9 in) at the top and of 200 millimetres (7.9 in) at the bottom with a height of 305 millimetres (12.0 in).The cone is placed on a hard non-absorbent surface.

  5. Mohr–Coulomb theory - Wikipedia

    en.wikipedia.org/wiki/Mohr–Coulomb_theory

    Mohr–Coulomb theory is a mathematical model (see yield surface) describing the response of brittle materials such as concrete, or rubble piles, to shear stress as well as normal stress. Most of the classical engineering materials follow this rule in at least a portion of their shear failure envelope.

  6. Anchor bolt - Wikipedia

    en.wikipedia.org/wiki/Anchor_bolt

    Concrete cone: after reaching the load-bearing capacity a cone shape is formed. The failure is governed by crack growth in concrete. [15] This kind of failure is typical in pull-out test. [16] [17] Splitting failure: failure is characterized by a splitting crack which divides the base material into two parts.

  9. Flow table test - Wikipedia

    en.wikipedia.org/wiki/Flow_table_test

    The cone is placed in the center of the flow table and filled with fresh concrete in two equal layers. Each layer is tamped 10 times with a tamping rod. Wait 30 seconds before lifting the cone. The cone is lifted, allowing the concrete to flow. The flow table is then lifted up 40mm and then dropped 15 times, causing the concrete to flow.
