Aug 7 (Reuters) - U.S. Concrete Inc RMIX.O posted wider-than-expected quarterly loss as demand from the construction industry waned due to the prolonged recession.

Second-quarter loss was $4.0 million, or 11 cents a share, compared with net income of $3.3 million, or 8 cents a share, a year ago.

Excluding items, the company's loss for the quarter was 19 cents a share, compared with a analysts average estimate of a loss of 3 cents a share, according to Reuters Estimates.

Revenue fell about 30 percent to $143.7 million. Analysts had forecast revenue of $161.02 million.

"Looking forward, we now expect full-year 2009 volumes to be down in excess of 25 percent year-over-year." said Chief Executive Michael Harlan in a statement.

However, the company expects to generate positive operating cash flow for the second half of the year.

Shares of the Houston, Texas-based company closed at $1.79 Thursday on Nasdaq.
