Concrete must be tested for quality assurance. At times, it is conducted for assessing structural conditions in their final form and before performing any repairs on a structure. The compressive strength of concrete is determined as an estimate by correlating mechanical properties like ultrasonic wave velocity and surface hardness with lab-based destructive tests. Concrete strength is measured by a compression test, which will determine the ability of the material to resist loads that may compress it. Compressive strength is determined by crushing a cylindrical specimen of concrete in a compression testing machine.  The results of a compressive strength test can be used to determine if the concrete mixture delivered to the construction site is able to meet the specified strength requirements for the job. Concrete cylinders are produced and cured following the procedures indicated in ASTM C-31, and the specimens are tested according to ASTM C-39. The test results depict the aver

Concrete compression testing is a crucial aspect of the construction process. Concrete is tested to make sure that the material specified and purchased is consistent with what was delivered to the construction site. There are many different testing methods to determine concrete compression, and they typically involve the use of specially designed tools and equipment to make sure that the procedure follows industry standards.  Concrete compression tests are typically conducted in a lab. Cylinder samples are used and operators follow AS1012 to ensure the correct procedure, sampling equipment, and other tools to be used for the test. The same standard specifies the requirements for determining the indirect flexural strength of concrete by splitting, and generic flexural testing.  The concrete compression test is actually the most widely conducted testing method to determine the compressive strength of concrete. Cylinders and cube samples are typically used for the test, but th

A concrete slump test measures the consistency of the material in a specific batch to determine the consistency, workability, and texture of the freshly made concrete. In a slump test, consistency determines the ease with which the material can flow. Hence, the test can help indicate the degree of wetness. Testing lets you determine the workability of the concrete, where wetter concrete is more workable compared to a drier mix, although the one with similar consistency can vary in its workability. The test can be used to determine the consistency of different batches of concrete, too.  To conduct a slump test , you need materials like the slump cone, base plate, slump funnel, a tamping rod, a ruler, and a mallet. The simplicity of these devices makes slump testing cost-effective in determining the workability of fresh concrete. In a test, the slump cone must be filled in layers, and each later will be compacted with the rod. The cone is then taken away and the vertical drop of

Concrete corrosion is a type of physicochemical, colloidal, or chemical disintegration and deterioration of solid structures and components and it is usually caused by reactive gases and liquids. It is a defect that can cause widespread damage to assets. Hence, it makes sense to make sure that preventative measures, testing, and coatings are applied to prevent or at least reduce the speed of corrosion. The corrosion of concrete reinforcement usually depends on the porosity and cover thickness of the concrete layer. Likewise, it may depend on environmental conditions, especially when those physical and geometrical properties are unable to meet requirements.  Reinforced concrete is typically designed and constructed with an estimated life span, which is controlled by asset-owners and designed by designers. The structure must be in a state of deterioration to the point that it cannot fulfil its functions any more. To prevent concrete corrosion, steps like controlling the quality and
