柳溪坝将是世界上第一座完全用碾压法修筑的混凝土重力坝。该坝碾压混凝土的低投标价格平均每立码是18.93美元,而用常规大体积混凝土施工的每立码混凝土的投标单价预计是65美元。迄今,对不同龄期、不同水泥用量的混凝土全部试验数据表明,碾压混凝土的强度一般要比同龄期、同水泥用量的常规混凝土所能达到的强度为高。 Willow Creek Dam will be the world’s first fully constructed concrete gravity dam. The average tender price for the dam roller compacted concrete is $ 18.93 per yard on average, while the tender price per yard of concrete used for conventional bulk concrete construction is estimated to be $ 65. So far, all the experimental data of concrete with different ages and different cement contents show that the strength of RCCs is generally higher than that of conventional concrete with the same age and cement content.
