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 ...

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 tes...

Soil testing is conducted to determine a particular soil's suitability for a construction project. Testing can be used to classify the soil and provide crucial information whether the soil possesses the integrity and the properties that are necessary to keep a structure stable. Soil testing is used in most construction projects including roadwork. Here are five soil testing-related trends you should consider for the most common applications: Plate load test – This test is commonly done at the foundation level of the soil. It is usually done according to local standards and specification to determine the soil's bearing capacity. The use of CBR test machines – The California bearing ratio test measures the strength of re-compacted sample of highway sub base, subgrade soil, and the subgrade using a penetration test. It is usually ideal for testing cohesive materials that have a particle size of less than 19mm. Soil triaxial...
