Seawater coral sand high-ductility cement-based composite material and preparation method thereof
The invention discloses a seawater coral sand cement-based composite material and a preparation method thereof, the seawater coral sand cement-based composite material comprises the following components by mass: 200-400 parts of cement, 600-800 parts of fly ash, 300-330 parts of seawater, 210-350 parts of coral sand, 1.6-2.6 parts of a water reducer, and 15-25 parts of fiber; the preparation method comprises the following steps: firstly, adding the coral sand and a certain mass of seawater into a stirrer, stirring for 1-5 minutes, and then standing for at least 10-30 minutes; adding the cement, the fly ash and the water reducing agent into the stirrer, and carrying out dry mixing for 2-5 minutes; then adding seawater and stirring for 3-5 minutes; then adding fibers and stirring for 3-9 minutes; finally, mold filling and demolding are conducted, and then curing is conducted to a specified age. Seawater and coral sand are used as raw materials, local materials can be used during island reef construction, and the cost is low; the preparation method is simple, green and environment-friendly.
本发明公开一种海水珊瑚砂水泥基复合材料及其制备方法，所述水泥基复合材料中各组分中以质量组分计，包括水泥200～400份、粉煤灰600～800份、海水300～330份、珊瑚砂210～350份、减水剂1.6～2.6份、纤维15～25份；制备时，首先将珊瑚砂和一定质量的海水加入搅拌机中搅拌1～5分钟，随后静置至少10～30分钟；然后将水泥、粉煤灰、减水剂加入搅拌机中干拌2～5分钟；接着加入海水搅拌3～5分钟；随后加入纤维搅拌3～9分钟；最后装模，脱模后养护至指定龄期。本发明利用海水和珊瑚砂为原材料，有助于岛礁建设时就地取材，成本低；本发明的制备方法简单，绿色环保。
