For the ramps, concrete finishers and an ACI-certified technician applied the low-slump shotcrete, a high powder-small stone mix that allows vertical placement. Microfibers resisted plastic shrinkage cracks and and rebar was installed on 16-inch centers for maximum stabilization. The ramps were then screeded and troweled.


Three concrete prisms, 100 × 100 × 500 mm, were cast for each of the three concretes.The individual probe elements (30 mm lengths of 10 M bar) were assembled as illustrated in Fig. 1 by attaching them to a polymethylmethacrylate (PMMA) rod, together with a 30 mm length of 316 stainless steel bar as a "reference electrode". All probe elements and the stainless steel were …


Concrete curing and concrete drying are two different processes. Curing is the process of hardening that begins immediately after the concrete is poured. The concrete curing process is usually mostly complete after 28 days or so. However, the concrete will continue to harden further for a significant amount of time after that.
