【 摘 要 】
Magnetite aggregate is used as a absorbing material. In order to study the mechanical properties, absorbing heat and deicing efficiency and frost resistance of magnetite concrete, I prepared the magnetite aggregate concrete with 0, 20%, 40%, 60%, 80% and 100% magnetite content, which be used to measure the compressive strength, flexural strength and surface temperature rise curve of magnetite aggregate concrete under microwave irradiation. The results show that the addition of magnetite aggregate can effectively improve the mechanical properties and deicing efficiency of concrete. With the increase of magnetite aggregate, the compressive strength and flexural strength increase gradually, and is approximately linear with the content of magnetite aggregate. With the increase of magnetite aggregate, the absorption and heating efficiency of magnetite aggregate concrete increases gradually. When the content of magnetite aggregate reached 100%, the efficiency of absorbing heat and deicing increased by 71.3% and 69.7% respectively.
