Standards for 7-day and 28-day strength test results

According to section 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.

Concrete Cube and Cylinder Test Results Acceptance Criteria

If the strength of a newly prepared concrete is determined by means of a standard-cured specimen then the following two factors are considered to accept the test results. The test result is accepted if the arithmetic average of any 3 of the consecutive strength test is equal to or greater than fc’.

Achieving top crushing results - -Sonthofen

Tips on Choosing a Concrete Crusher for Demolition

While jaw crushers use pressure to break up concrete impact crushers rely on impact as their name implies . Some impact crushers throw the rock against hard surfaces with such velocity that the rocks naturally break along internal fissures. Other impact crushers use hammers on the outer edge of a spinning rotor to break up materials.

Crushing Concrete Cube or Cylinder at 28 days

The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix.
