我国混凝土骨料的现状与问题

PRESENT SITUATION AND PROBLEMS OF CONCRETE AGGREGATES IN CHINA

针对目前我国天然矿石资源短缺、乱采滥挖砂石的现象屡禁不止、砂石质量严重失控的现状,应提高对砂石重要性的认识,引导砂石行业成为保护环境、开发建设用地、充分利用废弃资源的主力军。发展以工业废渣及淤泥、岩石为原料的人造轻骨料,积极开展再生骨料的应用研究工作。

In view of the shortage of natural stone resources in China at present and incessant and disordered exploitation and excavation of sand and gravel as well as the seriously out-of-controlled aggregates quality, consciousness of the importance of sand and gravel should be improved; the sand and gravel industry should be turned into the main force to protect environment, develop construction land and fully utilize waste resources. Artificial light aggregates made from industrial waste, silt and rock should be developed; and researches should be positively deployed on the application of regenerated aggregates.
