Description

technical field [0001] The invention belongs to the technical field of concrete preparation, and in particular relates to a steel slag radiation-resistant concrete and a preparation method thereof. Background technique [0002] The so-called nuclear radiation actually refers to alpha, beta, gamma rays and neutron flow. In general, α and β rays have only extremely weak penetrating ability, so these two rays do not need to be considered in actual production. Gamma rays have a very short wavelength, high frequency, high energy, and strong penetrating ability. Gamma rays have a considerable destructive effect on the human body, and when the radiation dose reaches a certain level, it is even fatal. The neutron flow also has a strong penetrating ability, and only a few specific elements such as boron, cadmium, lithium, and hydrogen can effectively absorb the neutron flow. The configuration of radiation-proof concrete must meet two primary conditions: on the one hand, the concre...
