  • Everything You Need to Know About Concrete Strength | Cor

    Concrete is considered by many to be a strong and durable material, and rightfully so. But there are different ways to assess concrete strength. Perhaps even more importantly, these strength properties each add different qualities to concrete that make it an ideal choice in various use cases.

  • The 28

    The American Concrete Institute recognizes 28 days or “the test age designated for determination of the specified compressive strength.”5 Therefore, when a specifier calls for 5,000 psi concrete at 28 days, this tells the concrete producer to select a mix design that will attain a minimum of 5,000 psi 28 days after manufacture.

  • Core Barrel

    Application. 1. Core barrel with bullet teeth is used for cutting an annular ring in rock or concrete (also reinforced concrete). 2. Core barrel with roller bits is used in very strong rock formations (compressive strength> 100 Mpa). 3. Cross cutter core barrel is mainly used to break rock cores which remain in the borehole after using a core

  • Different Grades of Concrete, Their Strength and Selection

    Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control. Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix.

  • Hydraulic concrete pile cutter

    BACKGROUND OF INVENTION. Most larger buildings today are constructed using precast concrete piles. Typically these concrete piles are hexagonal in cross section and have lengths varying from 20 to 80 feet (6 to 24 meters), they have diameters of 12, 14 and 16 inches (305, 355 and 405 mm, nominal), between opposed flat faces, between opposed angles the distances are approximately 15, 17 and 19
