摘要
本文对设计中的龙滩大坝混凝土原材料性能及坝基混凝土进行了不同龄期的徐变试验研究，结果表明、采用石灰岩为原材料轧制骨料拌制的混凝土。
The paper describes the test research into properties of dam concrete materialsand creep of dam foundation concrete in different ages for Longtan dam which is under design.The research results showes that the concrete prepared using the aggregate made fromlimestone has smaller creep and thermal expansion coeficient than the concrete used in otherprojects,in which sandstone and river pebble was used as the aggregate.
