Simulated microstructure and transport properties of ultra-high performance cement-based materials

Preparation of C200 green reactive powder concrete and its static–dynamic behaviors

“…RPC possess ultra-high static and dynamic strength, high fracture capacity, low shrinkage and excellent durability under severe condition [1][2][3][4]. The microstructure of RPC is optimized by precise gradation of all particles in the mix to yield maximum compactness [5][6][7][8][9][10][11]. With these merits, RPC has a great potential prospect in the protective shelter of military engineering and nuclear waste treatment, which has received significant concerns from experts across the word [12][13][14].…”

Durability and micro-structure of reactive powder concrete

“…H ℃ ydrated product will transform to the single crystallization, so that the amount of ettringite will reduce and it's difficult to ettringite crystallizes perfectly. In addition, Aft crystal is very difficult to obtain at low w/b [8,9] .…”

Parametric analyses of diffusion of activated sources in disposal forms

“…Ultra-high performance cement-based materials like reactive powder concretes (RPC) have been submitted to a leaching test in [15]. Microscopic observations have shown that de-ionised water leaching altered the matrix microstructure and that the ground quartz, fine sand and steel fibres were not involved in the degradation process.…”
