Preparation method of functional internal curing lightweight aggregate loaded with super absorbent resin
The invention discloses a preparation method of functional internal curing lightweight aggregate loaded with super absorbent resin. The preparation method comprises the following steps: (1) preparing agar gel according to a mass ratio of water to agar powder of 1000: 4.8; (2) taking out 100g of agar gel, heating in a water bath kettle, adding the super absorbent resin powder when the agar becomes soft, cooling, covering with a preservative film, and standing for 24 hours to obtain a mixture; (3) the mixture and the remaining agar gel are sequentially placed in an electric jacket to be heated, the agar gel is gradually liquefied in the heating process, and an agar-super absorbent resin mixed solution is obtained at the temperature of 80 DEG C. And (4) pouring the coral sand, stopping heating after the solution is boiled, soaking for 5 minutes, filtering, cooling, drying and screening to obtain the internal curing lightweight aggregate loaded with the super absorbent resin. The coral sand is used as a raw material, the cost is low, the manufacturing method is simple, and the performance problem of offshore high-strength concrete can be solved when the coral sand is applied to island construction.
本发明公开了一种负载高吸水性树脂的功能型内养护轻骨料的制备方法，包括以下步骤：(1)按照质量配比为水：琼脂粉＝1000：4.8制备琼脂凝胶。(2)取出100g琼脂凝胶，置于水浴锅中加热，待琼脂变软时加入高吸水性树脂粉末，冷却后覆盖保鲜膜放置24h，得到混合物。(3)将混合物和剩余琼脂凝胶依次置于电热套上中加热，加热过程中琼脂凝胶逐渐液化，80℃得到琼脂‑高吸水性树脂混合溶液。(4)将珊瑚砂倒入，待溶液煮沸后停止加热并浸泡5min，经过滤、冷却、干燥和筛分后获得负载高吸水性树脂的内养护轻骨料。本发明利用珊瑚砂作为原料，成本低、制作方法简单，运用于岛礁建设，能够解决海上高强混凝土的性能问题。
