Predicted patterns of fiber-concrete strength during compressive tests of cubes and cylinders

Abstract

There are two most popular approaches to determination of the compressive strength of concrete: testing cubes and testing cylinders. Usage of different samples leads to different results, which are intended to characterize one and the same property of the material – its compressive strength. The article discusses a general approach to determination of the compressive strength of cylinders and cubes. The analysis of factors affecting transition coefficients when testing the cylinder samples with the ratio of height to diameter is less than 2. The results of testing cubes and cylinders for compression made of fiber-reinforced concrete are presented.
