Zvyšování modulu pružnosti betonu s použitím mdroby jako hrubého drceného kameniva

Abstract

There is analyzed influence of moravian greywacke as coarse grinded aggregate on concrete elastic modulus. Concrete elastic modulus plays significant role on deformation properties of concrete structures. The experimental work was part of the compressive strength of concrete, static elastic modulus and dynamic elastic modulus measured on concrete with different recipes and the results were expressed using graphs. These readings were compared with values for the indicated standard ČSN EN 1992 -2 - Eurocode second.
