Compression testing is one of the most fundamental types of mechanical testing, alongside tensile and flexion tests. Compression tests are used to determine a material’s behavior under applied crushing loads, and are typically conducted by applying compressive pressure to a test specimen (usually of either a cuboid or cylindrical geometry) using platens or specialized . Abstract. This study aims to investigate the effect of waste steel slag (SS) as partially replaced with cement and fine aggregate on conventional concrete for different mixes named M25, M35, and M47 in terms of compressive strength (CS), electrical resistivity (ER), and piezoresistivity behavior. SS is a molten mixture of silicates and oxides that solidifies upon .5.1 Significance—The data obtained from a compression test may include the yield strength, the upper yield strength, the Young’s modulus, the stress-strain curve, and the compressive strength (see Terminology E6). In the case of a material that does not fail in compression by a shattering fracture, compres-Equipment: Neoprene pads evenly distribute compressive force; Retainer rings are placed on both ends of concrete cylinders and confine pads, so they do not extend beyond the specimen diameter; Polysaccharide powder serves as a lubricant for easy pad-change out; Gloves promote safety during testing; Whether you use the sulfur mortar capping method or neoprene pads .
Compressive strength is a fundamental parameter that informs the safety, quality and durability of a particular mix of concrete. Testing according to ASTM C39 is central to the QA/QC process. For over 80 years, ASTM C39 has been the industry standard test method for testing the compressive strength of concrete cylinder specimens. In this .
