Compression Test for Concrete - The Civil Sutras

Procedure for compression test of concrete. Clean the cylinder mold and coat the inside lightly with form oil, then place on a clean, level and firm surface, ie the steel plate. Collect a sample. Fill 1/2 the volume of the mold with concrete then compact by rodding 25 times. Cylinders may also be compacted by vibrating using a vibrating table.

Testing for Cement Content of a Concrete - The Civil Sutras

Compression Testing Cement content is important to allow engineers to gauge the structural stability of any building or concrete structure where it is used. High cement content on the other hand can cause concrete to suffer from excessive shrinkage and thermal cracking, which can cause the concrete to spall and thus be dangerous for a structure.

Tests on Concrete - The Civil Sutras

The first step is to take a test sample from the large batch of concrete. This should be done as soon as discharge of the concrete commences. The sample should be representative of the concrete supplied. The sample is taken in one of two ways: For purposes of accepting or rejecting the load: Sampling after 0.2 m3 of the load has been poured.

Testing pH of Concrete - The Civil Sutras

Although concrete typically begins its life at a highly basic pH of about 13, the pH values at exposed surfaces soon fall as reactions occur between carbon dioxide from the atmosphere and alkalis in the concrete—a process known as carbonation. Over time, fronts of carbonated concrete, with pH values of about 8.5, advance below exposed []

The compression test results revealed that the compressive strength of the UHPC mixes is correlated with their flow and entrapped air content . A greater flow or flowability is desirable to eliminate the entrapped air from the concrete mixes; a lower entrapped air content is likely to increase the compressive strength of UHPC.
