Indonesia's domestic cement sales were 12.5Mt in the first quarter, up 18.2 per cent from a year ago, data from PT Semen Gresik Tbk showed on Friday.       

March sales were 4.4Mt, up 16.2 per cent from the same month last year, the data showed, with most sales in Sumatra and Java islands.

Total domestic cement sales in 2011 reached 47.9Mt, a YoY rise of 17 per cent and growth is expected to continue this year as the country endeavours to meet its ambitious housing and infrastructure requirements.
    
PT Indocement Tunggal Perkasa Tbk, Indonesia's biggest cement firm by market value, has estimated national demand for cement will grow 8-10 per cent as infrastructure projects increase after a government law in December to speed up land acquisition.
