Radiation-resistant concrete protective agent and preparation method thereof
The invention relates to a radiation-resistant concrete protective agent. The invention is characterized in that the protective agent is composed of a dense water component, a radiation-resistant component, a slow neutron and fast neutron absorbing component, and a heavy micro-aggregate filling component. The dense water component is silicate mineral, and accounts for 0.5-1.0 wt% of the cementing material in the concrete. The radiation-resistant component is composed of active 2BaO.SiO2 and triethanolamine [N(C2H4OH)3] (TEA for short), wherein the active 2BaO.SiO2 accounts for 3.0-4.0 wt% of the cementing material in the concrete, and the TEA accounts for 0.02-0.05 wt% of the cementing material in the concrete. The slow neutron and fast neutron absorbing component is composed of high-alumina cement clinker, ascharite and natural gypsum, and accounts for 3.0-4.0 wt% of the cementing material in the concrete. The heavy micro-aggregate filling component adopts natural barite (mainly composed of BaSO42H4O), and accounts for 2.0-3.0 wt% of the cementing material in the concrete. All the components are mixed in a mixing machine to obtain the protective agent.
