Worked on a small power plant in Grit, Va. back in the 90's... We built a 4 acre water treatment/containment/settling pond out of concrete. The Supt. insisted on adding "superplaster" (liquid calcium carbonate) to the concrete mix so it would set faster... Within 6 months of finishing the project, the engineers condemned every square inch of concrete because it had set too fast - Becoming brittle and covered in hair-line cracks (about a 2 million dollar fuckup). Every bit had to be demolished and re-done.
