Concrete is very central to modern construction projects whose safety, strength and reliability are tested before use. In fact, if working in a concrete setting, the concrete checking practice is extended to old Rome and more far, so this makes it well established hence it is easy to treat concrete testing as a reference element to check out the quality of construction material. For what in fact the concrete is, it basically is a composite material consisting primarily of a binding medium in which particles or fragments of particles are present or it is usually a mixture of fine particles and coarse particles; in Portland cement, it is made up of a mixture of Portland cement and water, with or without additives.

Testing of the concrete:

Concrete testing is vital to ensure the strength and flexibility of built structures. Many organizations provides services with the title of concrete testing services to get it right the quality of concrete which is going to be used for your building. The checking of the quality ensure the safety of building that it will stay upright and will not fall down.

Compression strength test for the concrete:

For many of the concrete testing services, they think of this test as the most important one. Three samples of cylinders must be taken to test the compressive force, but they are not usually three samples, and sometimes they depend on the specifications of the test. There is a room for extra sample because one additional sample is taken into account if the previous two cubes or cylinders are tested for the compression test and if they fail unfortunately, the remaining sample is passed which is third one. Other possibility can be that if the testing services protocol requires 3 samples. The samples taken must be completely tested within 60 days.

Water absorption capability:
There is another test that will determine the extent to which concrete is tolerated. The three cube samples are taken from fresh concrete and given in to the treatment tank for 28 days or after 24 hours. The concrete sample will be removed and will be sent directly to laboratory to ensure that it is processed.

Water permeability testing:
Water permeability testing is one of the tests to determine the durability of concrete whether it will stay in rainy season or not. Three cubes of fresh concrete are taken and tested according to standards in 28 days of age. This type of testing must be taken from concrete elements such as foundations, concrete water tank, wall etc.
