evaluate the early strength of concrete as it cures in the field under ambient temperature conditions. Similar to concrete, grout strength is also typically evaluated through compressive strength testing of samples at 7 and 28 days. In order to better evaluate the early strength gain of grout used in augered cast-in-place (ACIP) piles, a study was

One of the drawbacks of pressurized grout remote backfilling was its high cost, mainly due to the high cost of Portland Cement. In the mid-1990’s, the AML Division began looking for a more cost effective, yet environmentally safe grout formulation. In 1995, a comprehensive grout testing research project determined that flyash from specific
