本实验研究分别对采用常规方法（ACI）设计的普通硅酸盐水泥（OPC）混凝土和采用密实配合比设计算法（DMDA）设计的高性能混凝土（HPC）进行了性能评价。通过工作性、抗压强度、吸水率、超声脉冲速度和表面电阻率等测试，研究了OPC和HPC样品的工程性能和耐久性。试验结果表明，HPC具有良好的保鲜性能，在强度和耐久性方面均优于OPC。
This experimental study evaluated the performance of normal ordinary Portland cement (OPC) concrete and high-performance concrete (HPC) that were designed by the conventional method (ACI) and densified mixture design algorithm (DMDA) method, respectively. Engineering properties and durability performance of both the OPC and HPC samples were studied using the tests of workability, compressive strength, water absorption, ultrasonic pulse velocity, and electrical surface resistivity. Test results show that the HPC performed good fresh property and further showed better performance in terms of strength and durability as compared to the OPC.
