Abstract
On the coefficient of prismatic strength of high-strength concrete
Incoming article date: 25.08.2013This paper studies the dependence of the ratio of prismatic strength (Rb) from cube strength (R) for high-strength concrete of classes B70 ... B110. Experiments were carried on the concrete cubes with an edge of 150 mm and prisms with a base 150x150 mm and a height 600 mm. The tendency to reduce the ratio Rb / R with increasing strength of the concrete is founded. A new relationship Rb = f (R) is offered
Keywords: high-strength concrete, physical experiment, prismatic strength, cube strength, the coefficient of the prismatic strength
