LABORATORY 1: Casting of Concrete Specimens Introduction Casting or Preparation of concrete specimens is required prior to the testing of compressive and flexural strength or any other test on concrete. For both tests, students will be divided into two groups and they will jointly cast the concrete specimens. For compressive strength test,
Introduction. Concrete compression is a complex phenomenon; a lot of factors influence the behavior of concrete under such loading. Three important factors affect concrete compression: the specimen size, geometry, and friction at its ends, all affect the observed results. ... Also, for concrete mixtures of higher strength, some …
9.2.1 Introduction. Compressive strength is one of the most important engineering properties of concrete, not only because concrete is employed primarily to resist compressive loads, but also because it is used as a measure of its overall quality.
Introduction. Concrete compressive strength testing is used to establish the characteristics of specimens when subjected to a weighing load. The strength is measured in N/mm2 or MPa. In most cases, such strengths are dependent upon the quantity and type of cement used in the concrete mix.
Splitting tests: The splitting tensile strength test involves a compressive force to a concrete cylinder or cube using a compressive testing machine. A force is applied perpendicular to the surface of the sample, causing it to split [ 12 ].
