Abstract:

During an investigation of the Troy Lock and Dam, New York, a core was recovered that contained part of a metal anchor that had been grouted into foundation rock. Since this grout was about 63 years old and had presumably been continuously below the water table, it provided an opportunity to study the effect of this environment for this period of time on the phase composition and microstructure of this grout. The phase composition of the grout was studied by X-ray diffraction its microstructure was studied by scanning electron microscopy. It was found that the grout had a normal composition and microstructure the environmental conditions had not had a significant effect on either composition or microstructure. The original water content had been fairly high as would be expected. Author
