鲁地拉水电站混凝土骨料料源选择研究

Research on selection of concrete aggregate sources for Ludila hydropower project

鲁地拉水电站混凝土工程量大,骨料料源有灰岩料场、砂岩料场、正长岩料场以及开挖碴料,开挖碴料又分为砂岩、正长岩2种,骨料料源复杂。通过对不同类型的骨料料源进行综合技术经济比较,最终选择以砂岩开挖碴料加工碾压混凝土粗骨料、以料场开采的正长岩为主加工碾压混凝土细骨料及常态混凝土粗、细骨料的方案。

Ludila hydropower project requires a large quantity of concrete, and the aggregate sources are from quarries of limestone, sandstone and syenite, and excavated materials including sandstone and syenite. The aggregate sources are very complex. Through technical and economic comparison of various aggregate sources, excavated sandstone is finally selected as the coarse aggregate of RCC, and the syenite from quarry as the fine aggregate of RCC and coarse and fine aggregates of conventional concrete.
