Abstract

Radiation shielding boxes in nuclear power plants suffer from dense and complex reinforcement and concrete that is not easy to vibrate. This places high demands on the flowability of concrete. In this study, the paste threshold method was used to carry out the paste threshold test on the flowability of self-compacting concrete containing magnetite and common aggregate. The test results show that: The flow of concrete containing magnetite aggregates in the same proportion is about 10% lower than that of concrete mixed with ordinary aggregates, and the T₅₀₀ expansion time rises by 35%; and a model for calculating the paste threshold of magnetite self-compacting concrete was developed. The model provides guidance for the design of magnetite self-compacting concrete.
