High-temperature-resistant waste ceramic high-performance concrete and preparation process thereof
According to the high-temperature-resistant waste ceramic high-performance concrete and the preparation process thereof, waste ceramic aggregate is adopted as aggregate, the performance and the structure of the concrete are optimized, and the mechanical property of the concrete at the high temperature is greatly improved; the stainless steel fibers are uniformly dispersed in a matrix by adopting a screening method, and a wide reinforcing, toughening and heat-conducting network is formed in the matrix. After the concrete is subjected to the high temperature of 800 DEG C for 1 hour, the 28d breaking strength reaches 28.0 MPa, which is improved by 131.4% compared with that of a control group; the 28d compressive strength reaches up to 124.8 MPa and is improved by 268.1% compared with that of a control group; the 28d fracture energy and the compression work are respectively up to 6992.43 J/m < 2 > and 399.19 kN.mm, which are respectively improved by 132.0% and 209.2% compared with a control group. According to the process, the green high-performance concrete with excellent high-temperature resistance can be obtained, and meanwhile, a way is provided for high-efficiency and high-added-value resource utilization of the waste ceramic.
