DOI: 10.1016/j.cemconcomp.2018.08.005
Abstract: Abstract Limited strain capacity and low tensile strength of cement-based materials make them brittle and sensitive to cracking, behavior that limits durability of cement-based applications. Rubber aggregates (RA) incorporation appeared to be a suitable solution… read more here.
