Flexural Tensile Strength of Concrete with Synthetic Fibers [PDF]

open access: yesMaterials, 2021
Fiber reinforcement is currently most often used in floors, railway sleepers, prefabricated structural elements such as slabs, beams and tanks, and in small architecture elements. Designing elements or structures made of fiber-reinforced concrete requires knowledge of its basic mechanical parameters.

Influence of additives on flexural strength of concrete [PDF]

open access: yesMATEC Web of Conferences, 2017
In earlier studies, the effect of chemical and mineral additives on the compressive strength of concretes was considered, but little attention was paid to the flexural strength of concrete. However, monolithic concretes of transport purpose, including road concretes, operate under conditions of tensile loads, which lead to their destruction. Therefore,
