WebApr 4, 2024 · Plastic concrete is a kind of flexible concrete cutoff wall material, which is used to solve the problem of poor coordinated deformation ability between ordinary concrete cutoff wall and surrounding soil. It has the characteristics of small elastic modulus and large limit strain, which greatly improves the operation condition of cutoff wall. WebMar 2, 2024 · The stress–strain characteristics of CW concrete are poor as compared with those of NA concrete at 3 and 7 days but there is not much difference in characteristics of the two types of concrete at 28 days. The split tensile strength of CW concrete is less but comparable to that of NA concrete.
