REVIEW BY MINERAL COMMODITIES 
 
NONMETALS 
 
 Cement.—Two plants on Oahu Island produced 1,444,000 barrels of portland
cement. They shipped 1,395,000 barrels 
—1,151,000 barrels in bulk and 244,000 barrels in paper bags. Seventy-three
percent went to ready-mixed-concrete companies, 9 percent to concrete product
manufacturers, 8 percent to building material dealers, 6 percent to contractors,
and 4 percent to government agencies and miscellaneous customers. 
 Cement shipments were 354,000 barrels less than in 1966; exports decreased
147,000 barrels and shipments for use in Hawaii dropped 207,000 barrels.
Total 
consumption of cement in Hawaii, including white and other special types
received from the U.S. mainland and 2,825 barrels from Japan, amounted to
1,344,000 barrels, 13 percent less than in 1966. 
 Raw materials used in cement production were 326,000 tons of coral limestone
and 65,000 tons of basalt and trachyte from quarries on Oahu. Silica sand,
gypsum, and grinding aids were imported. The two plants used 39.7 million
kilowatt-hours of electrical energy. 
 
 Clays.—Clays were mined on Oahu at a pit near Waimanalo and hauled
to a plant at Barbers Point for use in the manufacture of brick, tile, hollow
block,
