Hawaiian Cement history

The Plowshare Program was delayed by an international ban on nuclear testing that lasted until September 1, 1961.

In remote Hawai`i, by 1962 the Corps had completed construction of the Kawaihae deep draft harbor on the northwest coast of the Big Island pursuant to the national Rivers and Harbors Act.

In late 1967, HC&D became a wholly owned subsidiary of American Pipe and Construction Co. of Monterey Park, California (Ameron, Inc.). For many years, Ameron and HC&D supplied concrete pipe to many of Hawaii's major water transmission lines and sewage systems as a joint venture.

Four years later, in 1969, both the renamed "Kaiser Cement & Gypsum Corp." and Hawaiian Cement announced plans to greatly expand their production capacities in response to rising demands precipitated by a construction boom.

Incomplete detonation of two charges in the entrance channel necessitated a series of 16 remedial small detonations in December 1970.

In 1974, Hawaiian Cement also got a new name after the Cyprus Mines Corporation increased its ownership to 90.8%, having bought 45.4% from its partner in the enterprise, the American Cement Corporation, then known as Amcord, Inc.

Kaiser completed the conversion in June and Cyprus in October 1980.

The joint venture, originally named the American Concrete Pipe of Hawaii, sold the pressure pipe used in sewer projects throughout Honolulu. Its mainland partner was renamed Ameron c.1982, hence, Ameron HC&D.

The business slump continued into 1983, adversely affecting not only the cement producers but also ready-mix concrete and construction materials suppliers such as Ameron HC&D, Pacific Concrete & Rock Co. (PC&R) and Lone Star's own Hawaii Rock Products.

By October 1985 the "Hawaiian Cement Co." reappeared in Hawai`i, this time sporting a new logo designed by Momi Cazimero of Graphic House and described by the HA as being "developed from the letter 'C,' suggesting in its interlocked shape a familiar concrete block form."

Published by the National Park Service (NPS) of the Department of the Interior in 1993, the cultural report lists as the author Linda Wedel Greene who, according to the preface, led an investigative team of considerable size.

In 1995, Lone Star sold its 50% share of the company to Knife River Corp. (KRC), a subsidiary of North Dakota based MDU Resource Group.

Having changed ownership two times, the Kauai Electric Company, since 2002, operates as the Kauai Island Utility Electric Cooperative, owned and controlled by the consumers it serves.
