Study of the solubility of xonotlite

ce/papers, Volume 6, Issue 2, Page 238-245, September 2023., 2023
Abstract Xonotlite (Ca6Si6O17(OH)2) is a hydrated crystalline calcium silicate with CaO/SiO2 = 1, which forms under hy‐drothermal conditions at temperature above ∼100°C. It has good thermal stability, it dehydrates to wollastonite only at 770 to 800°C and shows a good resistance to high pressures.

Influence of Fiber Orientation on the Shear Properties of Steel Fiber‐Reinforced Reactive Powder Concrete Beams

Advances in Civil Engineering, Volume 2023, Issue 1, 2023., 2023
Steel fiber‐reinforced reactive powder concrete (SFRPC) has good mechanical properties and is thus useful for engineering applications. Generally, the fibers in SFRPC are randomly distributed. To study the effects of the amount, length, and orientation of steel fibers on the shear strength of SFRPC beams, nonreinforced aligned steel fiber‐reinforced ...
