Anti-radiation concrete and preparation method thereof
The invention discloses anti-radiation concrete and a preparation method thereof. The anti-radiation concrete is prepared from the following raw materials in parts by weight: 220-280 parts of cement;30-50 parts of mineral powder; 40-80 parts of fly ash; 1350-1400 parts of a heavy aggregate; 525-575 parts of a lightweight aggregate; 30-40 parts of a fiber additive; 25-35 parts of an expanding agent; 5-8 parts of a water reducing agent; 150-200 parts of water. The heavy aggregate is barite and heavy crystal sand, the light aggregate is basalt, the fiber additive comprises basalt fibers and titanium fibers, and the ratio of the basalt fibers to the titanium fibers is 1:(1-1.5). The anti-radiation concrete has the advantages that the volume weight is reduced, the mechanical property and the construction property are improved and the cost is reduced under the condition that the anti-radiation effect is guaranteed; in addition, the invention further provides a preparation method of the anti-radiation concrete, and the prepared concrete has excellent comprehensive performance.
本发明公开了一种防辐射混凝土及其制备方法，所述防辐射混凝土由包含以下重量份的原料制成：水泥220‑280份；矿粉30‑50份；粉煤灰40‑80份；重骨料1350‑1400份；轻骨料525‑575份；纤维添加物30‑40份；膨胀剂25‑35份；减水剂5‑8份；水150‑200份；所述重骨料为重晶石和重晶砂；所述轻骨料为玄武岩；所述纤维添加物包括玄武岩纤维和钛纤维，所述玄武岩纤维和钛纤维的比为1：（1‑1.5）。本发明的防辐射混凝土在保证防辐射的效果下，其具有降低容重、提高力学性能和施工性能以及减少成本的优点；另外本发明还提供了一种防辐射混凝土的制备方法，制备的混凝土具有较优的综合性能。
