The invention relates to a steel
slag radiation shield concrete and a preparation method thereof. The steel
slag radiation shield concrete comprises the following components in parts by weight: 1 part of
cement, 0.4-0.5 part of water, 4-8 parts of steel
slag sand, 0.01-0.03 part of water
reducing agent, 0.01-2 parts of barite and 0.01-0.03 part of
colemanite, wherein the steel slag sand comprises two kinds of steel slag sand with the particle size ranges of 0-5mm and 5-25mm according to the proportion of 1-3:1-3, and the f.CaO content of the steel slag sand is less than or equal to 3%; the water
reducing agent is selected from an FDN water
reducing agent and a polycarboxylate water reducing agent; and the
apparent density of the steel slag
radiation shield concrete is greater than 2900kg / m<3>. The steel slag
radiation shield concrete of the invention has good compactness, large
apparent density and high strength and meets the requirements of the
radiation shield concrete; the invention changes waste steel slag into valuable resources, reduces the environment
pollution, simultaneously lowers the consumption of mineral materials, and saves natural resources; and in addition, the steel slag used in the invention has abundant resources, low price and obvious economic benefit.
