Test methods for sprayed concrete — Part 4: Part 4: Measurement of flexural strengths

Scope

This document specifies the bending test methods on beam specimens for measuring the flexural
strengths of sprayed concrete, respectively applied to conventional sprayed concrete and fiber
reinforced sprayed concrete. The reinforcing fibers can be metallic fibers, synthetic or other fibers,
or a combination of fiber types. This document covers the measurement and determination of
flexural strength parameters such as first peak strength, ultimate strength, and residual strength of
sprayed concrete specimens under controlled loading conditions.
