Atlas Portland Cement Company

[1] For the construction of the Singer Building in New York City, 22,600 barrels of cement were used.

Some 151,000 barrels of Atlas cement were used in constructing the Empire State Building,[1] completed in 1931.

Changes in technology and automation mean that in the 21st century, 150-200 workers can do the work that used to take thousands of employees in the plants.

[6][7] On March 2, 1921, Affleck and thirty-nine other officers of cement corporations were indicted by a federal grand jury under the Sherman Antitrust Act for restraint of trade and attempts at monopoly.

The companies involved were alleged to have tightly controlled the supply of cement, refusing to sell any builder more than the amount needed for a single job, and preventing them from using any unexpected surplus on other jobs; prices quoted on cement were invariably the same to the penny.
