Abstract
High performance concrete with less cement content named as low cement high performance concrete (LcHPC) was used to form the top layer of a check dam to take the advantage of the low hydration heat in concrete. A full-scale field test was conducted to compare the erosive resistibility of LcHPC against that of normal concrete (NC). The measured average abraded depths for a designated LcHPC blocks after 24 months of continuous flow tests range from 53 to 78 mm, approximately 25–32% that of the companion blocks made with NC. The average compressive strengths of cored LcHPC samples taken after 28 days are 53.3 MPa, approximately 122% higher than that of the companion blocks. These data convince that the erosive resistibility of LcHPC is significantly higher than that of the NC.
