  • HOW TO DETERMINE OF BOND STRENGTH BETWEEN STEEL CONCRETE

    Jun 22, 2015The bond strength is the measure of the effectiveness of the grip between concrete and steel and has no standard quantitative definition. In pull out tests on plain bars, the maximum load generally represents the bond strength that can be developed between concrete and steel.

  • Applicability evaluation of cast

    In recent years, cast-in-place bored piles have been widely used in engineering constructions. However, the applicability of bored pile was constricted by the loss of concrete strength in the cold curing environment of permafrost. A temperature-tracking concrete hydration model was developed to clarify the refreezing process of the bored pile.

  • What are the types of concrete piles and what are the

    When the concrete hardens, the prestress cables are cut, with the tension force in the cables now producing compressive stress in the concrete pile. It is common to higher-strength concrete (35 to 55 MPa) in prestressed piles because of the large initial compressive stresses from prestressing.
