Coring Soil-cement Installed By Deep Mixing at Bostonís CA/T Project
J. R. Lambrechts, Scott Nagel

A core drilling method using PQ-size triple tube core barrel and fine diamond flush face bit with side water discharge was successfully used to cover representative specimens of extremely variable hardness soil-cement made by deep mixing. A soil-cement hardness identification procedure using the scratch test derived from soft rock identification procedures was employed in the field to quickly categorize the soil-cement core for strength and consistency or degree of heterogeneity.
