Pressive Strength Test Of Concrete Cylinder

Concrete com-pressive strength requirements can vary from 2500 psi (17 MPa) for residential concrete to 4000 psi (28 MPa) and higher in com-mercial structures. Higher strengths up to and exceeding 10,000 ... Strength test results from cast cylinders may be used for quality control, acceptance of concrete, or for estimating the concrete strength

    Standard Test Method for Compressive Strength of Concrete

    4.1 Cast-in-place cylinder strength relates to the strength of concrete in the structure due to the similarity of curing conditions because the cylinder is cured within the slab. However, due to differences in moisture condition, degree of consolidation, specimen size, and length-diameter ratio, there is not a unique relationship between the strength of cast-in-place cylinders and cores of the

    Mar 06, 2017 Compressive strength as a concrete property depends on several factors related to quality of used materials, mix design and quality control during concrete production. Depending on the applied code, the test sample may be cylinder [15 cm x 30 cm is common] or cube [15 cm x 15cm x 15 cm is the most common]. For example, as per ASTM C39, a
