Nuclear radiation protection concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses nuclear radiation protection concrete and a preparation method thereof. The nuclear radiation protection concrete is prepared from the following components: cement, an anti-radiation agent, heavy crystal sand, broken stone, silica fume, a retarder, a polycarboxylate superplasticizer, a defoaming agent, a thickening agent, an additive and water, the preparation method of the anti-radiation agent comprises the following steps: uniformly mixing barium powder, borosilicate glass, polyoxyethylene castor oil and ethanol according to a weight ratio of (20-28): (48-54): (5-10): 20, heating the mixture to 1200-1350 DEG C at a heating rate of 5-10 DEG C/min, and keeping the temperature for 1-2 hours; and then carrying out water quenching, drying, ball milling and sieving to obtain the anti-radiation agent with the particle size of less than or equal to 200 meshes. The invention further discloses a preparation method of the nuclear radiation protection concrete. The nuclear radiation protection concrete disclosed by the invention has a good anti-radiation effect, and meanwhile, the mechanical property and freezing resistance of the concrete can be improved.
本申请涉及混凝土的技术领域，具体公开了一种核辐射防护混凝土及其制备方法。本申请公开的一种核辐射防护混凝土，包括以下组分：水泥、防辐射剂、重晶砂、碎石、硅灰、缓凝剂、聚羧酸减水剂、消泡剂、增稠剂、外加剂、水；防辐射剂的制备方法为：将钡粉、硼硅酸盐玻璃、蓖麻油聚氧乙烯醚与乙醇按照（20‑28）：（48‑54）：（5‑10）：20的重量比进行均匀混合，将混合物以5‑10℃/min的升温速率升温至1200℃‑1350℃，并保温1‑2h；然后经水淬、烘干、球磨、过筛，得到粒度≤200目的防辐射剂。本申请还公开了上述核辐射防护混凝土的制备方法。本申请公开的核辐射防护混凝土具有良好的防辐射效果，同时还能提升混凝土的力学性能和抗冻性。
