Formation and Strength of Crystalline Calcium Silicate Hydrate Prepared by Single Autoclaving Process

Formation and Strength of Crystalline Calcium Silicate Hydrate Prepared by Single Autoclaving... Two kinds of calcium silicate paste containing tobermorite and xonotlite crystallines, were used to prepare calcium silicate hydrate products by a single autoclaving process. The mechanical strength and microstructure of these products were determined to investigate the hardening mechanism of calcium silicate hydrate material. The relationship between the forming pressure and mechanical strength and the observed microstructure revealed that the mechanical strength of this type of material is attributed to a mechanism of contact hardening. Increasing the forming pressure could enhance its mechanical strength. However, it was also found that there was an optimum forming pressure that produced the maximum mechanical strength. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advances in Structural Engineering SAGE

Abstract

Two kinds of calcium silicate paste containing tobermorite and xonotlite crystallines, were used to prepare calcium silicate hydrate products by a single autoclaving process. The mechanical strength and microstructure of these products were determined to investigate the hardening mechanism of calcium silicate hydrate material. The relationship between the forming pressure and mechanical strength and the observed microstructure revealed that the mechanical strength of this type of material is attributed to a mechanism of contact hardening. Increasing the forming pressure could enhance its mechanical strength. However, it was also found that there was an optimum forming pressure that produced the maximum mechanical strength.
