  • Shape and size effects on the compressive strength of high

    In this paper we investigate the influence of the shape and of the size of the specimens on the compressive strength of highstrength concrete. We use cylinders and cubes of different sizes for performing stable stressstrain tests. The tests were performed at a single axial strain rate, 10 6 s 1. This value was kept constant

    Assessment of Compressive Strength of Concrete Produced

    The tests carried out include slump test at its fresh state while compressive strength was carried out for the hardened concrete, also the vicat test was carried out on the cement brands to determine the setting time. Compressive strength at 28 days showed that Dangote

    Effect of specimen sizes, specimen shapes, and placement

    mon notion that concrete compressive strength is a unique material property is an erroneous one since the compressive strength of concrete changes based on specimen sizes and shapes due to its fracture characteristics. For most countries, sizes and shapes of test specimens to determine the compressive strength of the concrete are different.

  • Application of size effect to compressive strength of

    Well known as the size effect, the strength of a member tends to decrease when its size increases. Therefore, in view of recent increased interest in the size effect of concrete this research focuses on the size effect of two main classes of compressive strength of concrete: pure axial compressive strength and flexural compressive strength.

    Size effect in the strength of concrete structures

    The objectives of this paper are twofold. First, it compares the size effect formulae, (1) and (2), for tests on high strength concrete (HSC, nominal compressive strength 110 MPa) with a view to identifying their ranges of applicability. Beams (span to depths ratio of 4) with
