Abstract

The resistance as well as strain hardening and softening properties of UHPFRC depend on the type of matrix and mainly on the initial fibre dosage and final fibre distribution and orientation in the cast element. According to the final fibre distribution and orientation these properties may vary in a wide range. The strength and deformability distribution in a thin UHPFRC panel is studied. Tensile and flexural specimens cut in different directions and at different positions in the panel are analysed in order to determine locally the mechanical material properties. The real fibre dosage, distribution and orientation are determined. The results show a wide scatter of the mechanical properties, whereas the physical properties, especially the air permeability, are not affected by the mechanical scatter.

Ultimate tensile strength

Ultimate tensile strength (also called UTS, tensile strength, TS, ultimate strength or in notation) is the maximum stress that a material can withstand while being stretched or pulled before breaking. In brittle materials the ultimate tensile strength is close to the yield point, whereas in ductile materials the ultimate tensile strength can be higher. The ultimate tensile strength is usually found by performing a tensile test and recording the engineering stress versus strain.

Strength of materials

The field of strength of materials (also called mechanics of materials) typically refers to various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts. The methods employed to predict the response of a structure under loading and its susceptibility to various failure modes takes into account the properties of the materials such as its yield strength, ultimate strength, Young's modulus, and Poisson's ratio.

Physical property

A physical property is any property that is measurable, involved in the state of a physical system, whose value represents the intensity on the object's state and behavior. The changes in the physical properties of a system can be used to describe its changes between momentary states. A quantifiable physical property is called physical quantity. Measurable physical quantities are often referred to as observables. Physical properties are often characterized as intensive and extensive properties.
