Radiation-proof mortar and preparation method thereof
The invention relates to anti-radiation mortar and a preparation method thereof, and the anti-radiation mortar is prepared from the following raw materials in parts: 200-300 parts of ordinary Portland cement, 5-20 parts of high-alumina cement, 150-350 parts of barite sand, 100-150 parts of coarse sand, 50-100 parts of barium sulfate, 30-80 parts of dispersed latex powder, 30-55 parts of cellulose ether, 60-200 parts of glass fiber, 30-55 parts of a dispersing agent, 30-55 parts of a defoaming agent and 150-350 parts of expanded perlite. The ratio of the ordinary Portland cement to the high-alumina cement to the barite sand to the coarse sand is 0.5: 0.5: 5.44: 3, the content of barium sulfate in the barite sand is not less than 80%, and the preparation method of the anti-radiation mortar comprises the following steps: detecting and treating the raw materials before preparation. According to the anti-radiation mortar, the preparation method thereof, the expanded perlite and the glass fibers, the thermal stability of the anti-radiation mortar is remarkably improved, and after the hydration structure of the anti-radiation mortar is damaged, the expanded perlite and the glass fibers can still fill gaps of the anti-radiation mortar, so that the mortar is effectively prevented from cracking and falling off.
本发明涉及一种防辐射砂浆及其制备方法，包括以下份数的原料：普通硅酸盐水泥200‑300份、高铝水泥5‑20份、重晶石砂150‑350份、粗砂100‑150份、硫酸钡50‑100份、分散乳胶粉30‑80份、纤维素醚30‑55份、玻璃纤维60‑200份、分散剂30‑55份、消泡剂30‑55份、膨胀珍珠岩150‑350份，所述普通硅酸盐水泥、高铝水泥、重晶石砂和粗砂之间的配比为0.5:0.5：5.44:3，所述重晶石砂中硫酸钡含量不低于80％，所述一种防辐射砂浆制备方法，其制备方法包括以下步骤：制作前对各原料进行检测和处理。该防辐射砂浆及其制备方法，膨胀珍珠岩和玻璃纤维的设置，显著提升防辐射砂浆的热稳定性，在其水化结构受到破坏后，膨胀珍珠岩和玻璃纤维仍然能够对其缝隙进行填补，有效避免砂浆干裂脱落。
