Design and Optimization of Bulk Anti-radiation Concrete Mixing Ratio
As a radiation shielding material,anti-radiation concrete is widely used in medical buildings,the properties of its constituent materials and the design of the mix ratio play an important role in shielding radiation.Taking the concrete structure of the linear gas pedal room of the Cancer Hospital Branch of the Chinese Academy of Medical Sciences(Langfang Campus)as the engineering background,the research on the design and optimization of the mix ratio of radiation protection concrete were carried out.Through the performance test of raw materials,the high-quality constituent materials are screened,and the mix ratio is designed.Based on the mechanical properties test results of different mix ratios of concrete,the mix ratio is adjusted.Through the water penetration resistance and adiabatic temperature rise test of concrete,the optimal mix ratio of radiation-proof concrete is obtained considering the cost,and good results are achieved in practical engineering.
