What is it about?
Concrete heat treatment is commonly used to speed up early gaining rate in mechanical strengths. However, adding some other ingredients can help to improve this desired effect. The aim of this study was to investigate the value-added use of steel fibers in combination with heat curing on some mechanical and microstructural properties (compressive strength, modulus of elasticity, modulus of rupture, splitting tensile strength, direct tensile strength, X-ray diffraction and fracture surface observations) of high-performance concretes.

Why is it important?
The main purpose of this paper is to investigate the effect of heat curing on mechanical and microstructural properties of SFHPC and the possible early age improvements that lead to increasing the usability of this material in particular for precasting concrete elements.
Perspectives
Heat curing in combined with steel fiber could help to improve the final performance of the precast concrete and reduce the fabrication time.
