Let's say the work is progressing and test reports are being provided routinely. What do the contractor and concrete producer do with them? Step 1, normally, is to give the report a quick glance to look for a red stamp that signals an unsatisfactory result.
A certain quantity of concrete shall cast as a cube while pouring time of the concrete to find the compressive strength of concrete. Then the cube is to be tested by the Compression Testing Machine after completion of curing period 7 days and 28 days. Now, we are going to discuss the Compressive Strength of concrete with the detailed procedure.

The capacity of concrete is reported in psi – pounds per sq. inch in US units and in MPa – mega pascals in SI units.This is usually called as the characteristic compressive strength of concrete fc/ fck. For normal field applications, the concrete strength can vary from 10Mpa to 60 Mpa.

This report was initiated by a concrete laboratory report brief given out by Professor Mark Alexander in the 'CIV5002Z: Structural Concrete Properties and Practice' postgraduate course.
Cube or Cylinder samples are usually tested under a compression testing machine to obtain the compressive strength of concrete. The test requirements differ country to country based on the design code. As per Indian codes, compressive strength of concrete is defined as
Function why cube test is carried out because we want to determine the characteristic strength of the concrete. In this experiment, we already compress two concrete cube. First test is after seven day concrete have been harden and second test is after 28 day concrete have been harden.

*** BS5328 requires mean of two cube sample strength at 28 days as characteristic strength **** ACI318-08 requires mean of two sample (6"diax12" cylinder) strength at 28 days as comprerssive strength Note: Above results pertain to the unsealed samples supplied to the laboratory
Compression Test of the Concrete Specimen is most widely used test to measure its compressive strength. Two types of concrete specimen: Cubes & Cylinders are used for this purpose: Cubes of size 150mm are more common in Asia, Russia & European countries while Cylinders of 150mm in diameter & 300mm high are common in U.S and Australia.

According to section 22.214.171.124 of ACI 318-19 the specified compressive strength shall be based on the 28-day test results unless otherwise specified in the construction documents. 3- or 7-day test results are used to monitor early strength gain, especially when high early-strength concrete is used. However, 3- and 7-day test results are not ...
Compressive strength of concrete cube test provides an idea about all the characteristics of concrete.By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.
Evaluation of the concrete compressive strength in existing structures is an important problem, which is associated with structural reliability estimation as well as a quality control procedure.
