Cementation Processes of Naturally Aged Hawaiian Calcarerous Sands

Abstract

Researchers have studied cementation of calcareous sands for decades. While cementation increases static and cyclic strengths, it also reduces skin friction on piles. Cementation of sands in their own environment varies widely with many different factors. Obtaining undisturbed samples can be difficult and costly, and laboratory reproduction of samples has become an accepted method for testing calcareous materials. The focus of this research is on understanding the processes and effects of early cementation in calcareous sand. Understanding of these processes will allow researchers the ability to better estimate light cementation effects for various types of calcareous sands. The project compared results of cyclic and static triaxial tests, cone penetrometer tests, and Scanning Electron Microscope (SEM) photographs to show the differences between two distinctly varied calcareous sands at similar densities and aged for relatively short periods of time.
