摘要：Compared with ordinary concrete and high strength concrete, ultra-high performance concrete has more excellent mechanical properties and durability. It has great social and economic benefits to prepare ultra-high performance aeolian sand concrete using aeolian sand as aggregate. It is of great significance to study the durability of ultra-high performance aeolian sand concrete. The mechanical properties and durability of ultra-high performance concrete are analyzed and compared by optimizing mix ratio and optimizing mix ratio. The test results show that the compressive strength of ultra-high performance aeolian sand concrete loses obviously after 300 freeze-thaw cycles. However, the splitting tensile strength is not affected by the number of freeze-thaw cycles; the strength of ultra-high performance aeolian sand concrete is not affected by sulfate immersion; with the increase of the number of drywet cycle-sulfate erosion coupling cycles, the compressive strength and splitting tensile strength of ultra-high performance aeolian sand concrete decrease rapidly at first, then increase gradually, and then decrease rapidly.
