Jul 12, · Concrete Core Testing Procedures. IS Code for the Concrete Core and test specimen is mentioned in IS – PART- 4: This is specified in clauses 3 and 4. The recommended length/diameter ratio for concrete core samples is 2. After drilling, it is crucial to mark and identify concrete cores, recording their location and orientation within.

Improper capping or surface irregularities of specimens will cause a non-uniform load, yielding improper results. The proper method for capping is described in ASTM C , “Practice for Capping Cylinders.” End grinders or rubber caps can also be used to prepare and test concrete test specimens. The type of. This method covers the procedures for obtaining, preparing and testing cores drilled from concrete for length or compressive or splitting tensile strength determinations, and to determine the length of a core drilled from a concrete structure, particularly pavement. Test smart – Build right Why Take Cores? •Investigate low test results from standard-cured specimens •Develop correlation with other in-place or nondestructive (NDT) tests •Confirm interpretation of NDT methods •Obtain samples for petrographic analysis •Estimate the in-place “specified strength” for structural evaluations 4. The degree to which core-test results will reliably estimate strength of the in-place concrete is strongly influenced by the care taken in sampling, conditioning, storing, preparing, and testing the cores. This test method provides standardized procedures for obtaining and testing specimens to determine the compressive, splitting tensile, and flexural strength of in-place concrete. Core testing is the most direct method to determine the compressive strength of concrete in a structure. Generally, cores may be obtained to assess whether concrete in a new structure complies with strength-based acceptance criteria or to evaluate the structural capacity of an existing struc-ture based on the in-place concrete strength. strength, flexural strength and modulus of elasticity of cement concrete. 2. MAKING AND CURING COMPRESSION TEST SPECIMENS IN THE LABORATORY This clause specifies the procedure for making and curing compression test specimens of concrete in the laboratory where accurate control of the quantrties of matt.. rials and test conditions are.
