TL;DR: In this paper, the authors developed an ultra-high strength ductile concrete designated RPC (Reactive Powder Concrete), which was made possible by the application of a certain number of basic principles relating to the composition, mixing and post set heat curing of the concrete.

TL;DR: In this article, a study of several RPC compositions by Mercury Porosimetry, Thermogravimetric Analysis and X-ray diffraction made it possible to better understand their microstructural properties depending on their heat treatment.

TL;DR: In this paper, the authors used 29Si NMR using SPE/MAS technique to study the hydration of reactive powder concrete (RPC) and pozzolanic reaction.

TL;DR: A careful analysis of the 29 Si NMR signal of reactive powder concretes, composed of siliceous cement, silica fume, and crushed quartz, has been done in order to determine the hydration conditons on the kinetics of hydration.

TL;DR: In this article, the authors used two complementary techniques to exhibit the microposity of reactive powder concrete (RPC) and showed that RPC porosity mainly consists of pores with average sizes smaller than a threshold value, while the typical frequency dependence of measured proton relaxation rates proves unambiguously the influence of the paramagnetic impurities at the surface of the pores.
