2009年,成都市通过推广散装水泥使用,仅从供应量568万t来计算,就已经减少建设工地向大气中排放水泥粉尘2.4万t。近日,成都市散装水泥工作会在新津召开,2010年6月30日前,成都全市各区(市)县将完成划定当地禁止现场搅拌混凝土和砂浆范围,从而进一步消灭扬尘污染源。 In 2009, Chengdu, through the promotion of the use of bulk cement, had reduced the emission of 24,000 tons of cement dust to the atmosphere from construction sites only from the supply of 5.68 million tons. Recently, the work of bulk cement in Chengdu will be held in Xinjin. Prior to June 30, 2010, all districts, cities and counties in Chengdu will finalize the demarcation of the scope of on-site mixing of concrete and mortar, so as to further eliminate dust pollution sources.
