Erosive resistibility of low cement high performance concrete

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.
