The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days (f ck )- as per Indian Standards (ACI standards use cylinder of diameter 150 mm and height 300 mm). The characteristic strength is defined as the strength of the concrete below which not more than 5% of the ...
While in Britain and Europe, the standard specimen for testing the compressive strength is a cube specimen of concrete by size 150 × 150 × 150 mm (Kim and Seong-Tae, 2002). The cubes are smaller compared with the cylinder specimen of concrete, and the

For normal concrete and HSC, the concrete compressive strength test results from cube specimens are generally higher than cylinders specimens [6]. As states in BS 1881, the compressive strength of concrete gained by cylinder specimens is equal to 0.8 times of the compressive strength gained by cube specimens.
Compressive strength data were collected from 1, 3, 7, and 28 day concrete test specimens from both the 4 by 8-in. cylinders and 6 by 12-in cylinders. Three specimens per age per mix were tested. Average compressive strengths of each mix design are listed
· AIM: To determine the compressive strength of concrete specimens as per IS: 516 - 1959. APPARATUS: i) Compression testing machine conforming to IS: 516 - 1959 AGE AT TEST: Tests should be done at recognized ages of the test specimens, usually being 7
Size of test cylinder Q. We want to specify the use of 4 x 8 in. (100 x 200 mm) instead of 6 x 12 in (150 x 300 mm) cylinders for evaluation and acceptance of structural concrete. Do the ACI Building Code requirements permit this? A. Section 26.12.3.1 of ACI 318-19 allows the use of 4 x 8 in. (100 x 200 mm) or 6 x 12 in. (150 x 300 mm) cylinders for strength tests provided that …
the compressive strength of concrete as the maximum aggregate size used in concrete mixes is normally 20 mm. According to GS 2006, Cl.16.59(6): The size of the test cube shall be 100 mm for concrete with the maximum aggregate size not exceeding 206
· The advantages of 4x8s are: They are easier for the technician to make. They weigh about 9 pounds compared to 29 pounds for a 6x12, making them easier to handle (and less likely to be damaged in handling). The smaller size takes up less space in curing chambers. With the smaller cross-sectional area, testing high strength concrete is easier ...
Answer (1 of 2): It has everything to do from what Bo Miller said regarding wall effect to the interaction between testing surface and concrete in compression. Consider this, a smaller sized cylinder has lesser surface area in contact with the testing (load applying
· 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 compression-testing machine.

· Concrete compression is complex. Yet, understanding this behavior is indispensable for design. There are three main factors that affect concrete compression results: the specimen size, shape, and friction at its ends. These factors affect the observed phenomena, and they affect each other. This paper aims to review the current knowledge on ...
