                      CEMEX COMPLETES SALE OF U.S. ASSETS

MONTERREY, MEXICO, March 31, 2005 - CEMEX, S.A. de C.V. (NYSE: CX) announced
today that it has completed the sale of certain CEMEX assets in the Great Lakes
region of the U.S. to Votorantim Participacoes S.A.

Votorantim acquires the Charlevoix and Dixon-Marquette cement plants, and
certain distribution terminals located in the Great Lakes Region.

CEMEX began evaluating alternatives to divest these assets in 2004, after
reviewing its strategic position in the U.S. The transaction was structured as
a sale of assets. CEMEX will keep its distribution terminal located in Detroit.
The value of the transaction is approximately U.S. $ 389.5 million.

Total production capacity of both cement plants is close to 2 million metric
tons a year, which has represented approximately nine percent of the current
operating cash flow generation of CEMEX's U.S. business prior to the RMC
acquisition.

CEMEX is a growing global building solutions company that provides products of
consistently high quality and reliable service to customers and communities in
more than 50 countries throughout the world. The company improves the
well-being of those it serves through its relentless focus on continuous
improvement and efforts to promote a sustainable future. For more information
