Autor: María Celeste Torrijos, Raúl Luis Zerbino, Bryan Barragán

Publikováno v: Construction and Building Materials. 22:1780-1788

This study analyses the mesostructural homogeneity of plain and steel fibre reinforced self-compacting concrete (SFR-SCC) to be used in slender elements of considerable height, avoiding the use of conventional reinforcement. Tests in the fresh state

Publikováno v: Cement and Concrete Composites. 25:767-777

A RILEM Draft Recommendation was proposed in 2001 for obtaining the stress versus crack opening (σ–w) response of steel fibre reinforced concrete through a uniaxial tension test. The present study analyses the robustness of the recommended test th
