Philippines: Cement producers in the Philippines have asked the Department of Trade and Industry (DTI) to impose mandatory standards on the raw materials used to ensure that quality standards are being followed. These standards would also effect producers of finished products that make significant use of cement. DTI Undersecretary for consumer welfare, Zenaida C Maglaya, made the announcement following a recent meeting of Cement Manufacturers Association of the Philippines (CeMAP).

According to Maglaya, CeMAP would like raw materials such as fly ash and aggregates to be placed under mandatory standards following complaints from contractors working on infrastructure projects. CeMAP said it will take years to find out the impact of poor quality fly ash. "We are asking CeMAP to submit their study because this is a technical issue," Maglaya said.

Maglaya explained that the standards for raw materials for cement are voluntary under the Philippine law. Being voluntary, Maglaya said, the responsibility lies on the end manufacturer although this can still be raised before the DTI. The move to standardise raw materials of cement and end-products using cement has followed a crackdown by the Department of Public Works and Highways against contractors of government infrastructure projects.
