Dissolution Kinetics of Tuff Rock and Mechanism of Chemical Bond Formation at the Interface with Cement Grout
Published online by Cambridge University Press: 26 February 2011
Abstract
The interaction of tuff rock and cement was studied to evaluate the effectiveness of sealing of tuff boreholes with cementitious grouts. Previous studies indicated chemical bond formation between tuff and cement. Dissolution studies were carried out on Topopah Spring member tuff and on tuff with cement. The results indicate the formation of calcium silicate and calcium aluminosilicate hydrates; phase identification is confirmed by XRD studies. The significance of the results obtained and their implications on properties of the interfacial region are included.
