  • Compressive Strength of Concrete Cylinders The Constructor

    · The compressive strength of the concrete cylinder is one of the most common performance measures performed by the engineers in the structural design Here, the compressive strength of concrete cylinders is determined by applying continuous load over the cylinder until failure occurs The test is conducted on a compressiontesting pressive strength testing of concrete is generally a performance check of the mix delivered to the project So, most field cylinders are made for quality control and acceptance of the product as purchased The practice for this type of testing is to follow the "standard curing" method found in ASTM C31 / AASHTO T 23 The initial curing environment is controlled and protected, and theConcrete Cylinder Testing From the Field to the Lab· Concrete's compressive strength determines whether the concrete placed in a structure can bear the weight of what's on top of it, or if it will splinter into a million pieces and cause the structure to collapse It is highly important for engineers to know how strong concrete is, and so construction materials testing companies send their field technicians to various construction sites to makeASTM Standard Test Method C39: Compressive Strength of

    · In North America, cylinder compressive strength is widely used as a proxy for any number of other concrete properties, in addition to its obvious role relating to the compressive strength of the structural concrete In the history of modern structural concrete, compressive strength is one of the most, if not the most, important property in terms of verifying acceptability of a wide range ofConcrete compressive strength can vary from 2500 psi (17 MPa) for residential concrete to 4000 psi (28 MPa) and higher in commercial structures Some applications use higher strengths, greater than 10,000 psi (70 MPa) WHY is Compressive Strength Determined? Compressive strength results are used to ensure that the concrete mixture as delivered meets the requirements of the specifiedCIP 35 Testing Compressive Strength of ConcreteCompressive strength as a concrete property depends on several factors related to the quality of used materials, mix design and quality control during concrete production Depending on the applied code, the test sample may be cylinder [15 cm x 30 cm is common] or cube [15 cm x 15cm x 15 cm is the most common] For example, as per ASTM C39, a standard test method is given to get the compressiveCompressive Strength Test Of Concrete Cubes Engineering
