Indonesia’s largest cement maker PT Semen Gresik sold 1.12Mt of cement in January, up 7 per cent from the same month a year ago, according to the Indonesian Cement Association.  In a report, the industry group said Semen Gresik sold 1.02Mt of cement in the local market during the month, up from 966,927t a year earlier. The company exported 94,783t against 76,938t in the same month in 2005.  Semen Gresik’s cement sales grew a modest 4.5 per cent to 16.34Mt in 2005 from 15.64Mt in the previous year as strong domestic sales offset weaker exports.
