* the table carries recommendatory / information nature as the increase of characteristics of concrete can differ depending on various factors
(quality of cement and its producer, water cement ratio, plasticity of concrete, rubble and sand fraction, presence of various chemical additives)
** explanations to table sections (strength characteristics):
"Bending" - a column showing a surplus of durability of concrete on stretching in case of a bend in comparison with a sample without a fiber
"Compression" - durability surplus on compression in comparison with a sample without a fiber
"Axial" - durability surplus on axial stretching in comparison with a sample without a fiber
