Procedures described are applicable to the compressive strength test results required by ACI, ACI, and similar specifications and codes. By this single test, one can judge whether concreting has been done properly or not and whether the structure has the required strength as per the specifications This guide provides an introduction to the evaluation of concrete strength test results. Standard Test Method The compressive strength of concrete cube test is a measure of the performance and strength of a given concrete mixture. Statistical concepts described are applicable for the analysis of other common concrete test results, including Concrete compressive strength can vary from psi (MPa) for residential concrete to psi (MPa) and higher in commercial structures. Check the balance is clean, operational and Compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and reported in units of pound-force per square inch (psi) or Scope * This test method covers determination of the compres sive strength of hydraulic cement mortars, usingin. or [mm] cube specimens. NOTE1—Test This standard covers teste; for the determination of compressive strength, flexural strength and modulus of elasticity of cement concreteMAKING 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 Check the sample number written on the cube matches the test schedule and that the date is correct by consulting the cube register. Check the balance is clean, operational and that the calibration certificate is valid. Concrete tests — Compressive strength of hardened concreteScope. An example of this is given below: C40/ Theis the compressive Check the sample number written on the cube matches the test schedule and that the date is correct by consulting the cube register. Some applications use higher strengths, greater than, psi (MPa). WHY is Compressive Strength Determined? This standard specifies a method of determining the compressive strength of test specimens of The concrete minimum compressive strength will be specified by the client/designer in a specific format.
